Description

  The present invention relates to a mammography treatment apparatus that treats a lesion position discovered by X-ray imaging with an MR (Magnetic Resonance) apparatus or an ultrasonic therapy apparatus.

  Conventionally, mammography is used to extract fine lesions of early breast cancer that cannot be detected by palpation or visual inspection. It is possible to recognize malignant breast cancer satisfying certain conditions (2 cm or less, no lymph node metastasis) with an MR image by an MR apparatus. When a lesion such as a tumor is found on an MR image, treatment with focused ultrasound under MR guidance is performed, but it is difficult to confirm a microcalcification lesion (MC) on the MR image.

  However, mammography has been introduced into screening, and many MCs have been discovered. If MC is found, the benign / malignant decision is made by mammography, needle under ultrasound guide, and mammotome biopsy. Microcalcification is often accompanied by malignant non-invasive ductal carcinoma. If it is judged as malignant, in order to see the spread, MR images are collected again without reflecting the position information of the microcalcification lesion (MC), and the operation range of the skin incision surgery is set.

  It is necessary to identify the lesion position with mammography and irradiate MR imaging or focused ultrasound to the lesion position. After mammography imaging with a compression plate, the compression is released and MR device or When the compression plate is fixed by an ultrasonic therapy apparatus, it is difficult to reproduce the lesion position specified by mammography.

  FIG. 1 is a diagram showing a mammography treatment apparatus according to the first embodiment of the present invention. The mammography treatment apparatus of the present invention is an apparatus that compresses and fixes a breast with a compression plate and shares a lesion position found by mammography (mammography apparatus) with other apparatuses. The compression plate of this mammography treatment device can be attached to and detached from the bed, chair, or MR operation bed, and can be imaged and treated with mammography, MR device, and focused ultrasound device while the breast is compressed with the compression plate. Become. That is, the compression plate has a mechanism separated from the mammography body.

  The mammography treatment apparatus shown in FIG. 1 is an X-ray on a mammography 20 in a state where one breast of a patient is compressed from the left and right with a compression plate 10 (actually fixed in the configuration shown in FIG. 2) fixed to a chair. This shows the case of taking a picture (sitting system). The mammography treatment apparatus includes a mammography 20 that performs X-ray imaging, two compression plates 10 that compress the breast, a compression plate fixing column 12 that supports and fixes the compression plate 10, and a compression plate fixation column 12. It is comprised by the support part 13 which supports another instrument, and the fixing screw 14 fixed to the armrest of the chair 5. FIG. The compression plate 10 is composed of two plates so that the breast can be compressed alone even when it is not attached to the mammography apparatus.

  The configuration around the compression plate fixing column 12 will be described below. As shown in FIG. 2, the support portion 13 is fixed to one surface of the compression plate fixing support portion 12 with a fixing screw 19, and the fixing screw 14 is provided at the tip of the support portion 13. A fixing groove 17 for fixing the compression plate 10 is formed on the side surface of the compression plate fixing column 12. It can be attached to and detached from the armrest of the chair 5 by the compression plate fixing column part 12, the support part 13, and the fixing screw 14 shown in FIG.

  For example, the patient's breast is compressed with the compression plate 10 from the side, and the compression plate is fixed by the compression plate fixing column 12. The compression plate fixing column 12 is fixed to the armrest of the chair 5 on which the patient is seated by a support portion 13 and a fixing screw 14. X-ray imaging is performed by the mammography 20 with the breast pressed and fixed in this manner.

  In addition, the ultrasonic applicator support part 11 for ultrasonic therapy can be installed in the compression board fixed support | pillar part 12, and the lesion position discovered after X-ray imaging is specified for ultrasonic therapy, and it uses for ultrasonic therapy. be able to.

  In addition, the patient can be transferred to an intraoperative image diagnostic apparatus for performing positioning and treatment planning of the ultrasonic therapy apparatus while being fixed by the compression plate 10. An image marker for position registration may be provided on the sitting / side-down position compression board / bed / chair / patient. These positioning methods will be described later.

  Next, adjustment of the compression thickness by the compression plate will be described with reference to FIG. FIG. 3A shows an example of a mechanism for adjusting and fixing the compression thickness by the fixing screw 15 of the compression plate 10. A column 18 is provided at one end of the compression plate 10, and the two compression plates 10 are fixed horizontally by the column 18. A fixing screw 15 is provided on the side where the support column 18 is provided, and the fixing screw 15 is fixed so as to be engaged with the fixing groove 17. The fixing screw 15 can be turned and fixed at a predetermined thickness. FIG. 3B shows an example of a mechanism that compresses the compression plate 10 to a desired thickness by the ratchet mechanism 16 and fixes it with the thickness. Further, pressing the release lever 21 can release the compression of the compression plate 10.

  FIG. 3 shows an example in which the apparatus is attached to a mammography, but the ultrasonic therapy apparatus is also provided with the same compression plate fixing column portion 12 as that of the mammography. In both cases, a mechanism for fixing to the mammography compression plate fixing support 12 with a screw exists independently of a mechanism for adjusting the compression thickness, and further, upper and lower independent compression plates 10 are provided. Therefore, the compression plate 10 can be fixed to and removed from the mammography 20 or the ultrasonic therapy device without releasing the compression plate 10 while maintaining the compression thickness.

  Further, by fixing the plate below the compression plate 10 in contact with the detection surface pedestal, the fixed position can be accurately reproduced between the mammography 20 and the ultrasonic therapy apparatus. Further, by combining with the setting method of the ultrasonic irradiation region, it becomes possible to accurately irradiate the affected part position identified by stereo imaging with the mammography 20 with the ultrasonic therapy apparatus.

  Next, a case where the breast is fixed with a compression plate fixed to the bed and X-ray imaging is performed with the mammography 20 (side position system) will be described with reference to FIGS. 4 and 5. FIG. 4 is a view showing a mammography treatment apparatus in a lateral position. FIG. 4 shows a case where X-ray imaging with mammography 20 is performed in a state where one of the breasts of a patient is pressed from the left and right with a compression plate 10 fixed to the side surface of the bed. Since each configuration of the mammography apparatus shown in FIG. 4 is the same as that shown in FIG. 1, the same reference numerals as those in FIG.

  The configuration around the compression plate fixing column portion 12 fixed to the bed will be described below. As shown in FIG. 5, the support portion 13 is fixed by a fixing screw 14 at a predetermined position on the side surface of the mat 7 installed on the bed 6. The support plate 13 is fixed with a compression plate fixing column 12, the compression plate 10 is fixed to the compression plate fixing column 12, and the detector 8 is installed below the compression plate 10. In a state where the patient lies down, the breast is sandwiched and fixed by the compression plate 10, X-ray imaging is performed by the mammography 20 in this state, and an X-ray image can be obtained by the detector 8.

  Next, a method for moving the patient from the mammography 20 to the MR apparatus or the ultrasonic therapy apparatus with the breast fixed by the compression plate will be described with reference to FIGS. FIG. 6 is a diagram illustrating a case where the mat on which the compression plate 10 is installed is moved and installed on the MR operation bed 30. At the time of X-ray imaging, the mat 7 on which the compression plate 10 is fixed is placed on the bed 6. The bed 6 is provided with a caster having a lock function. The caster is moved to the MR operation bed 30 of the MR apparatus 31 (or ultrasonic therapy apparatus), and the mat 7 is slid. The mat 7 is a material that is transparent to X-rays and does not cause artifacts in MRI imaging.

  FIG. 7 is a diagram showing a case where the compression plate fixing column portion fixed to the armrest of the chair and the chair are adapted to the MR operation bed. As shown in FIG. 7A, the compression plate fixing column 12 is fixed to the left and right armrests 41 and 42 with screws. A plurality of fixing holes are formed in the left and right armrests 41 and 42, and the fixing position of the compression plate fixing column portion 12 can be shifted. The armrests 41 and 42 are supported by a column 44, and the column 44 can be removed according to the apparatus. In addition, the caster part 43 can also be removed. Thus, when fixing the compression board fixing support | pillar part 12 to the left and right armrests 41 and 42, it presses with the breast sandwiched up and down from the front of the patient. When used in the MR apparatus and the ultrasonic therapy apparatus, as shown in FIG. 7B, the backrest part 40 can be placed on the MR operation bed 30 by being tilted horizontally.

  FIG. 8 is a diagram showing a case where the compression plate fixing column portion fixed to one armrest of the chair and the chair are adapted to the MR operation bed. As shown in FIG. 8A, the compression plate fixing column 12 is fixed to one armrest 41. The armrests 41 and 42 are supported by a column 44, and the column 44 can be removed according to the apparatus. The caster part 43 can also be removed. Furthermore, the armrest 42 which is not used for fixing can also be removed. The caster part can also be removed. Thus, when fixing the compression board fixing support | pillar part 12 only to the armrest 41, it presses by pinching a breast up and down from the patient's right side. When used in the MR apparatus and the ultrasonic therapy apparatus, as shown in FIG. 8B, the backrest part 40 can be placed on the MR operation bed 30 by being tilted horizontally.

  It should be noted that as shown in FIGS. 7A and 8A, it is possible to perform MR imaging with the vertical MR apparatus while in the sitting position.

  Next, a configuration of the compression plate 55 having a mechanism capable of compressing the breast alone without being fixed to a chair, a bed, etc. and a method for mounting the compression plate 55 on a patient will be described with reference to FIGS. FIG. 9 shows an undergarment 50 for fixing a compression plate 55 similar to a brassiere. The underwear 50 shown in FIG. 9A has a hook (not shown) on the back, a strap 51 whose length can be adjusted, and a compression plate fixing jig 52. The two compression plates 55 are fixed by the compression plate fixing jig 52, and are fixed by pressing the patient's breast. As shown in FIG. 9B, a hole 54 is formed in one breast portion of the undergarment 50. In addition to fixing the compression plate 55 with the compression plate fixing jig 52, the surface tape 53 provided at the tip of the strap and the surface tape provided on the compression plate 55 are connected to connect the compression plate 55 and the undergarment 50. Reinforce the fixing.

  On the other hand, FIG. 10 shows a compression plate 56 for fixing to the underwear 58 and the shape of the underwear 58. A face tape 57 is provided in a predetermined width on one side of the non-compressed surface of the two compression plates 56 shown in FIG. When the patient's breast is sandwiched from above and below by this compression plate 56, the state shown in FIG. 10B is obtained. FIG. 10C shows a case where the patient wears the underwear 58, presses and fixes the breast with the compression plate 56, and the face tape 57 and the underwear 58 are connected. As shown in FIG. 10D, the underwear 58 has a face tape 59 for stopping the compression plate 56. Further, a hole 54 is formed in one breast portion of the underwear 58. The compression plate 56 has two plates bonded to the left and right surfaces or three surfaces with strong rubber, and the breast is inserted by expanding the two plates from the surface not stopped by the rubber. In addition, although this surface tape has a width and size that can firmly press and fix the breast, other fixing means may be used as long as it has an equivalent function.

  Next, an alignment mechanism between the mammography 20 and another device will be described. First, an example in which the compression plate 10 is mechanically fixed and aligned is shown. FIG. 11 is a diagram illustrating a case where the ultrasonic applicator support 11 is not installed on the compression plate fixing column portion 12 and a case where the ultrasonic applicator support 11 is installed. FIG. 11A shows the case where the compression plate 10 is installed on the compression plate fixing column 12 and FIG. 11B shows the case where the ultrasonic applicator support 11 is installed. The ultrasonic applicator support 11 can be attached to and detached from the pressing plate fixing column 12. By mechanically fixing in this way, alignment can be easily performed between the mammography, the MR apparatus, and the ultrasonic therapy apparatus.

  Next, a method for performing alignment with the marker of the compression plate 10 will be described. FIG. 12 is a diagram showing an MR image marker using glass and oils. As shown in FIG. 12A, positioning is performed by a marker 60 provided on the compression plate 10. As shown in FIG. 12B, the marker 60 is provided with oils (baby oil or the like) 62 in a glass ball 61. Thereby, since a marker part is projected on the image acquired by X-ray imaging and MR imaging | photography, it can align easily with each image. The marker 60 is not limited to that shown in FIG. 12B, and a metal piece such as lead may be used. A plurality of markers 60 are arranged inside the X-ray detection region of the compression plate 10 and as much as possible outside. In addition, it is desirable that the upper compression plate 10 and the lower compression plate 10 are alternately arranged at positions where they do not overlap with each other in the X-ray image and the markers 60 have different sizes.

  On the other hand, it is possible to perform alignment by collecting positional relationship information between the marker 60 and the compression plate 10 from the X-ray image. A method for performing alignment by collecting positional information in the depth direction of the X-ray image will be described below. The measurement of the position of the calcified lesion by stereo imaging is measured using a conventional technique (the user points on the screen), converted into the specified calcification position with respect to the reference position of the compression plate 10, and the coordinates are transmitted to the treatment planning apparatus. In the case of a method in which the fixed position of the compression plate is mechanically fixed, coordinate conversion uses a fixed value in design.

  In the case of a method using an X-ray marker, first, a marker position is automatically calculated from a mammography image by automatic recognition processing. In the recognition method, after filtering, threshold processing such as hysteresis threshold is performed, labeling processing is performed to extract individual connected regions, and reference values such as the known area and shape of each region are calculated and judged by those values A method of extracting only correct markers by performing processing is adopted. Thereafter, the position of the center of gravity of the extracted marker area is obtained, and the marker position is obtained. There are a method of obtaining the position of the marker position in the depth direction (X-ray projection axis direction) from a stereo image and a method using digital tomography. If the depth information is used, the positions (distances) of the markers 60 of the upper and lower compression plates 10 are calculated, so that the thicknesses of the two compression plates 10 can also be measured. Thereafter, the coordinates of the calcification mark position in the coordinate system of the compression plate are obtained from the extracted marker position and the pointed calcification mark position, and the coordinates are transmitted to the treatment planning apparatus.

  Further, the calcification position is marked with the mammography 20, and the mark of the MR image is displayed, whereby the irradiation position (irradiation range) by the ultrasonic apparatus can be determined.

  On the other hand, the alignment for extracting a plurality of marker positions from the MR image in a three-dimensional manner using the above-described method of collecting the position information in the depth direction of the X-ray image and performing the alignment will be described below. The treatment planning system has a function of setting the region as an ROI. The user determines the irradiation required area on the screen on which the MR image is displayed, and inputs the result as the irradiation required area. Using the extracted plurality of marker positions and position information of the irradiation required area, the position of the irradiation required area with respect to the reference coordinate system of the compression plate is calculated. Using the information of the calculated calcification mark position with respect to the reference coordinate system of the compression plate, the calcification mark position is displayed on the display screen of the MR image. This mark assists the user in finding a tumor and determining the irradiated area.

  Registration of an X-ray image and an MR image will be described. A transmission image from an angle captured by the mammography 20 is reconstructed and presented as an MR image with reference to a marker, video, laser, or the like.

  Next, an MR operation bed having an ultrasonic applicator mounting portion will be described with reference to FIG. FIG. 13 is a cross-sectional view of the MR operation bed 30, and the compression plate fixing column portion 12 is installed on the MR operation bed 30. The compression plate 10 is fixed to the compression plate fixing column 12 by a fixing groove 17, and an ultrasonic applicator mounting portion 65 is installed at the lower portion of the compression plate 10. A water bag (or jelly or the like) 66 is attached to the upper portion of the ultrasonic applicator attachment portion 65. Treatment is performed by specifying a treatment range by imaging with an MR apparatus and irradiating ultrasonic lesions on the breast lesion through the water bag 66.

  Next, the compression plate 10 provided with holes for passing ultrasonic waves will be described with reference to FIG. As shown in FIG. 14, a hole 70 is provided in the compression plate 10, and a water bag 66 or the like is disposed on the upper portion of the hole 70, whereby ultrasonic waves generated from the transducer 71 can be irradiated to the breast through the hole 70.

  FIG. 15 is a view showing a compression plate provided with a cut line. As shown in FIG. 15A, a cut line 75 is formed on one surface of the compression plate 10. When the lesion position is specified from the X-ray image or the MR image, as shown in FIG. 15B, a hole 76 is provided around the specified position along the cut line 75, and ultrasonic waves can be irradiated.

  FIG. 16 is a view showing a compression plate provided with fine holes. As shown in FIG. 16A, a small-diameter fine hole 77 is formed on one surface of the compression plate 10. When the lesion position is specified from the X-ray image or the MR image, as shown in FIG. 16B, a hole 78 is provided around the specific position along the fine hole 77, and ultrasonic waves can be irradiated.

  FIG. 17 is a view showing a cross section of a compression plate provided with an oblique cut hole. As shown in FIG. 17, the compression plate 10 is formed with an opening 79 whose cut is not perpendicular. When the lesion position is identified from the X-ray image or the MR image, a water bag 66 or the like can be disposed on the upper portion of the opening 79 and the breast can be irradiated with ultrasonic waves generated from the transducer 71 through the opening 79. In this case, since the opening 79 is formed along the incident angle (beam width) of the ultrasonic wave, it is possible to irradiate the ultrasonic wave with an accurate focus.

  Not only the shape and position of the hole of the compression plate 10 shown in FIGS. 14 to 17 but also a method of shifting the position of the hole, a method of replacing the comb-type compression plate, and the like can be applied. It is also conceivable that the compression plate 10 is made of a material that allows easy passage of ultrasonic waves. For example, if the compression plate 10 is made of a material having an acoustic impedance that is relatively close to that of the human body, such as polycarbonate, a hole for ultrasonic irradiation becomes unnecessary. Polycarbonate is a material that can make the compression plate 10 thin, has hardness, is difficult to bend, and has sufficient heat resistance (135 degrees, self-extinguishing).

  As described above, by using the X-ray apparatus, the MR apparatus, and the treatment apparatus while the breast is compressed, the same lesion position and treatment range can be easily specified among the X-ray apparatus, the MR apparatus, and the treatment apparatus. . This makes it possible to easily treat the lesion position and treatment range identified by focused ultrasound, and particularly to treat breast cancer with MC as quickly as possible.

  According to the present invention, in a state where the breast is compressed by the compression plate structure provided with a hole or the like through which the focused ultrasonic wave is passed, the position specified by the X-ray imaging is not misaligned and sufficiently covered. It becomes possible to accurately irradiate focused ultrasound.

  In addition, according to the present invention, by providing a marker on the compression plate, X-ray imaging, MR imaging, and treatment can be realized while the breast is still compressed, and the X-ray apparatus, the MR apparatus, and the treatment apparatus can be accurately connected. Can be aligned.

  Therefore, it becomes possible to treat the breast cancer first discovered by the mammography 20 using the focused ultrasound therapy apparatus, and it becomes possible to apply the focused ultrasound therapy to more patients. It has the effect of increasing profits.

  Although the treatment plan using the MR apparatus has been described, it is possible to replace it with CT. CT can be performed in a short time of about 5 minutes and is effective for patients with claustrophobia. In the case of CT, the metal portion needs to be made as small as possible because it is too dark in metal and produces artifacts, but aluminum screws can be used. The shape of the compression plate 10 has a streak artifact on its extension if there is a straight part or a flat part, so that it is necessary to prevent the part to be seen from entering the surface. The direction for opening the hole for the ultrasonic device is set to a shape that does not affect the CT image.

  In addition, when photographing with CT (Computed Tomography) while compressing the breast with the compression plate 10, a round (rounded cross section) is made so that there is no flat portion in the hole of the compression plate. It is desirable to make it. This is to prevent the CT image artifacts from being superimposed on the extension of the plane.

  The mammography 20 is applicable not only to the flat detector shown in FIGS. 1 and 4 but also to other X-ray apparatuses.
