Description
Technical Field
The present invention relates to an X-ray imaging apparatus and a method for adjusting a display angle of an X-ray image by using the X-ray imaging apparatus.
Background
For example, an X-ray imaging apparatus used for performing an examination or an operation of a circulatory system or the like includes: an X-ray irradiation unit provided with an X-ray tube; an X-ray detector such as a flat panel detector that detects X-rays emitted from the X-ray irradiation unit and having passed through the subject; a C-shaped arm having an arc-shaped guide portion and supporting the X-ray tube and the X-ray detector; a slide mechanism which slidably supports the C-shaped arm by engaging with the arc-shaped guide portion; a rotating mechanism for supporting the C-shaped arm via the sliding mechanism in a manner of rotating around the axis facing to the horizontal direction; and a turning mechanism for turning the C-shaped arm around the vertical axis. An X-ray image obtained by the X-rays detected by the X-ray detector is displayed on a display unit such as a liquid crystal display panel.
In such an X-ray imaging apparatus, when the C-arm is rotated, the X-ray image displayed on the display unit is also rotated, and the direction of the image is changed. Therefore, conventionally, the orientation of the X-ray image displayed on the display unit is fixed by rotating the X-ray detector in accordance with the rotation angle of the C-arm (see patent document 1).
Fig. 7 is a plan view schematically showing a state where the orientation of an X-ray image is adjusted by such a conventional X-ray imaging apparatus. In the figure, a state is shown in which an X-ray image obtained by X-rays detected by the flat panel detector 32 supported by the arm 13 is displayed on the monitor 17 as a display unit.
As shown on the left side in fig. 7, in a state where the arm 13 is not rotated, an X-ray image obtained by the X-rays detected by the flat panel detector 32 is displayed in an upright state on the monitor 17. On the other hand, as shown in the center of fig. 7, in a state where the arm 13 is rotated, an X-ray image obtained by the X-rays detected by the flat panel detector 32 is displayed in a tilted state on the monitor 17. In order to display the X-ray image in an upright state, the flat panel detector 32 may be rotated with respect to the arm 13 as shown on the right side in fig. 7.

Disclosure of Invention
Problems to be solved by the invention
When the turning angle of the arm 13 is small, the X-ray image displayed on the monitor 17 can be set to an upright state only by turning the flat panel detector 32 by a small angle with respect to the arm 13. However, when the turning angle of the arm 13 is increased, the rotation angle of the flat panel detector 32 with respect to the arm 13 also needs to be set large. For example, in order to rotate the flat panel detector 32 by a large angle such as 360 degrees with respect to the arm 13, it is necessary to perform wiring processing and the like, and a large-scale mechanism is necessary. Further, if the rotation angle of the flat bed detector 32 with respect to the arm 13 is increased, a long time is required from the start of rotation of the flat bed detector 32 to the end of the rotation.
In this regard, it is also conceivable to rotate an X-ray image obtained by X-rays detected by the flat panel detector 32 by image processing instead of rotating the flat panel detector 32 with respect to the arm 13. However, when such a configuration is adopted, there is a problem that the image quality of the X-ray image displayed on the monitor 17 is degraded by the complementary calculation for rotating the X-ray image.
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an X-ray imaging apparatus and an X-ray image display angle adjustment method that can quickly rotate an X-ray image to an appropriate angle while simplifying a rotation mechanism of an X-ray detector for an arm.
Means for solving the problems
An invention described in a first aspect is an X-ray imaging apparatus including: an arm that supports the X-ray irradiation unit and the X-ray detector in a state facing each other; an arm turning mechanism that turns the arm around a vertical axis; and a display unit that displays an X-ray image detected by the X-ray detector, wherein the X-ray imaging apparatus further includes: a swivel angle detector that detects a swivel angle of the arm; a rotation mechanism that rotates the X-ray detector relative to the arm within a range of at least 90 degrees; a rotation angle detector that detects a rotation angle of the X-ray detector with respect to the arm; an image processing unit that rotates the X-ray image displayed on the display unit by 90 degrees each time through image processing; and a control unit that controls the image processing unit to change the rotation angle θ 2 at which the image is rotated by the image processing unit by 90 degrees each time, and controls the rotation mechanism to change the rotation angle θ 3 at which the X-ray detector is rotated with respect to the arm by an angle smaller than 90 degrees so that θ 1 is θ 2+ θ 3, when θ 1 is a rotation angle of the arm, θ 2 is a rotation angle at which the image is rotated by the image processing unit, and θ 3 is a rotation angle of the X-ray detector with respect to the arm.
An invention described in a second aspect is an X-ray imaging apparatus including: an arm that supports the X-ray irradiation unit and the X-ray detector in a state facing each other; an arm turning mechanism that turns the arm around a vertical axis; and a display unit that displays an X-ray image detected by the X-ray detector, wherein the X-ray imaging apparatus further includes: a rotation mechanism that rotates the X-ray detector relative to the arm within a range of at least 90 degrees; and an image processing unit that rotates the X-ray image displayed on the display unit by 90 degrees each time through image processing.
A third aspect of the invention is directed to a method of adjusting a display angle of an X-ray image for adjusting a display angle of an X-ray image displayed on a display unit using the X-ray imaging apparatus according to the second aspect of the invention, wherein when a turning angle of the arm is represented by θ 1, a rotation angle at which an image is rotated by the image processing unit is represented by θ 2, and a rotation angle of the X-ray detector with respect to the arm is represented by θ 3, the rotation angle θ 2 at which the image is rotated by the image processing unit is changed by 90 degrees with respect to the turning angle θ 1 of the arm, and the rotation angle θ 3 of the X-ray detector with respect to the arm is changed within an angle range smaller than 90 degrees, so that θ 1 is θ 2+ θ 3.
ADVANTAGEOUS EFFECTS OF INVENTION
According to the inventions described in the first to third inventions, the X-ray image displayed on the display unit can be arranged at an appropriate angle by rotating the X-ray image detected by the X-ray detector by an angle of 90 degrees each time through image processing and by rotating the X-ray image by an angle smaller than 90 degrees by the rotation of the X-ray detector relative to the arm. Therefore, by setting the range of rotation of the X-ray detector with respect to the arm to be at least 90 degrees, the rotation mechanism of the X-ray detector with respect to the arm can be made simple in structure. Further, since the angle of rotation of the X-ray detector with respect to the arm can be set to an angle smaller than 90 degrees, the time until the X-ray image displayed on the display unit is arranged at an appropriate angle can be set to a short time. Further, since the X-ray image is rotated by 90 degrees at a time by image processing, it is possible to prevent image quality from being degraded due to the rotation of the image.

Detailed Description
Embodiments of the present invention will be described below with reference to the drawings. Fig. 1 is a perspective view of an X-ray imaging apparatus according to the present invention, and fig. 2 is a perspective view showing the imaging carriage 1 viewed from the opposite side of fig. 1. The X-ray imaging apparatus is an apparatus for performing X-ray fluoroscopy and X-ray imaging during a surgical operation, and includes an imaging cart 1 and a monitor cart 2.
The imaging carriage 1 includes: a main body 11; an X-ray irradiation unit having an X-ray tube 21 and a collimator 23 that defines an irradiation region of X-rays irradiated from the X-ray tube 21; a flat panel detector 32 as an X-ray detector that detects X-rays emitted from the X-ray tube 21 and passing through the subject; and a C-shaped arm 13 that supports the X-ray irradiation unit and the flat panel detector 32 in a state of facing each other. The flat panel detector 32 having a rectangular shape is supported by a support portion 33 at the distal end of the C-arm 13, and is rotated with respect to the C-arm 13 by the action of a rotation mechanism disposed inside the support portion 33.
The main body 11 has a carriage-like structure, and a front wheel 10, which is a wheel for changing the direction, a pair of left and right rear wheels 12, which are drive wheels rotated by driving of a motor, not shown, and a pair of left and right grips 25, which operate the traveling direction of the main body 11, are arranged on the main body 11. A control unit 50 (see fig. 4) is provided in the main body 11, and the control unit 50 executes various controls including imaging control for performing X-ray imaging or X-ray fluoroscopy under predetermined conditions, turning control of the flat panel detector 32, and rotation control of an X-ray image, which will be described later.
The C-arm 13 has a substantially arc shape, and supports an X-ray irradiation unit including the X-ray tube 21 and the collimator 23 and a flat panel detector 32 as an X-ray detector in a state where an axis of X-rays from the X-ray irradiation unit to the flat panel detector 32 coincides with an arc diameter of the C-arm 13. The C-arm 13 is supported to be slidable with respect to the support portion 14. The support portion 14 is disposed on the main body 11, and the support portion 14 is coupled to a coupling portion 24 that rotates about a horizontal axis together with the C-shaped arm 13 and the like. The connection portion 24 rotates around the vertical axis with respect to the main body 11. Therefore, the C-arm 13 rotates around the vertical axis together with the X-ray tube 21, the collimator 23, and the flat panel detector 32 as the connection portion 24 rotates. The turning angle of the C-arm 13 is detected by a turning angle detector 47 (see fig. 4) including a rotary encoder and a potentiometer disposed on the support shaft of the coupling portion 24.
As shown in fig. 2, an LCD touch panel 26 is disposed on the upper surface of the main body 11. A plurality of operation switches indicating various operation items required for fluoroscopy or radiography, a fluoroscopic image, a photographed image, and the like are displayed on the LCD touch panel 26.
On the other hand, the monitor carriage 2 includes a housing 15, the housing 15 supports a monitor 17 as a display unit, and includes an input unit 16 configured by a storage-type keyboard or the like, and the monitor 17 displays an X-ray image obtained by X-rays detected by the flat panel detector 32. The housing 15 is movable by the action of a plurality of wheels 18, 19.
Fig. 3 is a schematic diagram of a turning mechanism for turning the rotary flat probe 32 with respect to the support portion 33 at the distal end of the C-type arm 13.
The flat panel detector 32 is coupled to a support shaft 41, and the support shaft 41 faces a direction perpendicular to the lower surface (X-ray detection surface) (a normal direction to the X-ray detection surface). The support shaft 41 is disposed at the center of the rectangular flat panel detector 32. The support shaft 41 is rotatably supported by a bearing 42, and a gear 43 is fixed near the upper end of the support shaft 41. The gear 43 meshes with a gear 44 fixed to a rotating shaft of a motor 45. Therefore, the flat panel detector 32 is rotated about the support shaft 41 by driving the motor 45. The rotation angle of the flat panel detector 32 is detected by a rotation angle detector 46 including a rotary encoder or a potentiometer attached to the motor 45. Further, the rotation angle range of the flat panel detector 32 is a range of at least 90 degrees. That is, the flat panel detector 32 may be rotated within a range of 90 degrees (for example, within a range of plus or minus 45 degrees). This makes it possible to simplify the turning mechanism including the wiring and the like of the flat panel probe 32 for the C-arm 13.
Fig. 4 is a block diagram showing a main control system of the X-ray imaging apparatus according to the present invention.
The X-ray imaging apparatus described above includes a control unit 50 that controls the entire apparatus. The control unit 50 is constituted by a computer with software installed therein. The functions of the respective units included in the control unit 50 are realized by executing software installed in a computer. The control unit 50 includes an image processing unit 51 and an angle calculation unit 52 as functional components, the image processing unit 51 rotates the X-ray image displayed on the monitor 17 by an angle of 90 degrees at a time through image processing, and the angle calculation unit 52 calculates a rotation angle θ 2 of the X-ray image rotated by the image processing unit 51 and a rotation angle θ 3 of the flat panel detector 32 with respect to the C-type arm 13. The control unit 50 is connected to the X-ray tube 21, the flat panel detector 32, the input unit 16, the monitor 17, the motor 45, the rotation angle detector 46, and the rotation angle detector 47.
Next, an operation of rotating the X-ray image rotated in accordance with the rotation of the C-arm 13 by an appropriate angle in the X-ray imaging apparatus having the above-described configuration will be described. Fig. 5 is an explanatory diagram for explaining the relationship among the turning angle θ 1 of the C-type arm 13, the rotation angle θ 2 at which the image displayed on the monitor 17 is rotated by the image processing unit 51, and the turning angle θ 3 of the flat panel detector 32 with respect to the C-type arm 13.
Fig. 5 shows a state in which the C-arm 13 is rotated by an angle θ 1 with respect to the imaging carriage 1. The turning of the C-arm 13 is performed by a manual operation of holding and turning the C-arm 13 by an operator. However, the C-arm 13 may be rotated by driving a motor or the like.
When the C-arm 13 is rotated by the angle θ 1, the X-ray image displayed on the monitor 17 as the display unit is also rotated. Therefore, in this X-ray imaging apparatus, when the C-arm 13 is rotated, the image processing unit 51 shown in fig. 4 is controlled by an instruction of the control unit 50 to change the rotation angle θ 2 at which the image processing unit 51 rotates the image, and the rotation mechanism shown in fig. 3 is controlled to change the rotation angle θ 3 at which the flat panel detector 32 is rotated with respect to the C-arm 13 by the rotation mechanism.
In this case, when the turning angle of the C-arm 13 is θ 1, the rotation angle at which the image is rotated by the image processing unit 51 is θ 2, and the rotation angle of the flat panel detector 32 with respect to the C-arm 13 is θ 3, the angle calculation unit 52 shown in fig. 4 calculates the angle θ 2 and the angle θ 3 so that θ 1 becomes θ 2+ θ 3. Then, an instruction is sent from the control unit 50 based on the calculation result of the angle calculation unit 52, the image processing unit 51 is controlled to change the rotation angle θ 2 of the image rotated by the image processing unit 51 by 90 degrees every time, and the rotation mechanism is controlled to change the rotation angle θ 3 of the flat panel detector 32 with respect to the C-type arm 13 by the rotation mechanism within a range of an angle smaller than 90 degrees.
Fig. 6 is a table showing the relationship among the turning angle θ 1 of the C-type arm 13, the rotation angle θ 2 at which the image is rotated by the image processing unit 51, and the rotation angle θ 3 of the flat panel detector 32 with respect to the C-type arm 13.
For example, when the rotation angle θ 1 of the C-type arm 13 is 45 degrees, the rotation angle θ 2 at which the image is rotated by the image processing unit 51 is 0 degree, and the rotation angle θ 3 of the flat panel detector 32 with respect to the C-type arm 13 is 45 degrees. When the turning angle θ 1 of the C-type arm 13 is 100 degrees, the rotation angle θ 2 at which the image is rotated by the image processing unit 51 is 90 degrees, and the rotation angle θ 3 of the flat panel detector 32 with respect to the C-type arm 13 is 10 degrees. When the turning angle θ 1 of the C-type arm 13 is 170 degrees, the rotation angle θ 2 at which the image is rotated by the image processing unit 51 is 90 degrees, and the rotation angle θ 3 of the flat panel detector 32 with respect to the C-type arm 13 is 80 degrees. When the turning angle θ 1 of the C-type arm 13 is 200 degrees, the rotation angle θ 2 at which the image is rotated by the image processing unit 51 is 180 degrees, and the rotation angle θ 3 of the flat panel detector 32 with respect to the C-type arm 13 is 20 degrees.
When the rotation angle θ 1 of the C-type arm 13 is 170 degrees, the rotation angle θ 2 of the image rotation by the image processing unit 51 may be 180 degrees, the rotation angle θ 3 of the flat panel detector 32 with respect to the C-type arm 13 may be 10 degrees (-10 degrees) in the opposite direction, and when the rotation angle θ 1 of the C-type arm 13 is 200 degrees, the rotation angle θ 2 of the image rotation by the image processing unit 51 may be 270 degrees, and the rotation angle θ 3 of the flat panel detector 32 with respect to the C-type arm 13 may be 70 degrees (-70 degrees) in the opposite direction. Similarly, when θ 1 is 200 degrees, it can be treated as 160 degrees (-160 degrees) in the opposite direction.
The angle calculation unit 52 also determines θ 2 and θ 3 in consideration of the rotation in the forward and reverse directions. At this time, in order to make the time required for rotating the flat panel detector 32 shorter, it is desirable to select θ 2 and θ 3 that minimize θ 3.
When the X-ray image is rotated by the image processing unit 51, there is a problem that the image quality of the X-ray image displayed on the monitor 17 is degraded by the supplementary calculation for rotating the X-ray image. However, when the X-ray image is rotated by 90 degrees every time in units of 90 degrees, the image can be rotated without performing a supplementary operation using matrix transformation or the like. Therefore, when the above-described configuration is adopted, the quality of the X-ray image displayed on the monitor 17 is not degraded.
In the case of the above-described configuration, the rotation angle range of the flat panel detector 32 may be set to a range of at least 90 degrees, and the flat panel detector 32 may be rotated within a range of 90 degrees. This makes it possible to simplify the turning mechanism including the wiring and the like of the flat panel probe 32 for the C-arm 13. Further, since the rotation angle of the flat panel detector 32 with respect to the C-type arm 13 is reduced, the time until the X-ray image displayed on the monitor 17 is arranged at an appropriate angle can be set to a short time.
In the above-described embodiment, the flat bed detector 32 is rotated with respect to the C-type arm 13 by driving the motor 45, but the flat bed detector 32 may be manually rotated by an operator. In the above-described embodiment, the image processing unit 51 automatically rotates the image, but the image processing unit 51 may rotate the X-ray image by 90 degrees every 90 degrees in units of 90 degrees based on an instruction of the operator.
In the above-described embodiment, the rotation angle θ 3 of the flat bed detector 32 is detected by the rotation angle detector 46 including a rotary encoder or a potentiometer provided to the motor 45, but the angle θ 3 may be recognized by a scale or the like provided to the support 33 or the like. In the above-described embodiment, the turning angle θ 1 of the C-arm 13 is detected by the turning angle detector 47 including the rotary encoder and the potentiometer disposed on the support shaft of the coupling portion 24, but the angle θ 1 may be recognized by a scale or the like provided on the body 11 or the like. When such a configuration is adopted, the operator may input the angle θ 1 or the angle θ 3 recognized from the scale or the like from the input unit 16, calculate θ 2 and θ 3 based on the input values, and display the calculation result on the LCD touch panel 26 as needed.
