The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Referring to fig. 1, fig. 1 is a schematic flow chart of a display method of a scatter image according to a first embodiment of the present disclosure. The method comprises the following steps:
step 11: and acquiring sample detection data to obtain multi-dimensional signal data corresponding to each particle in the sample.
In some embodiments, obtaining sample detection data is based on a sample analysis device. And the sample analysis equipment analyzes the sample to be detected to obtain the number of various cell particles in the sample to be detected. The obtained sample detection data are different for different detection items, and taking a blood sample as an example, the blood sample is subjected to leukocyte detection, and the particle types include ghost, lymphocyte, monocyte, eosinophil, basophil, neutrophil and the like. As for reticulocyte detection, particle types include red blood cells, reticulocytes, platelets, white blood cells, and the like.
Taking a sample analysis device as a cell analyzer and a sample to be detected as a blood sample as an example, the analysis of the blood sample to be detected is as follows:
adding corresponding reagents to the blood sample to be detected, and enabling the blood sample to be detected with the added reagents to pass through the detection area. A light source, such as a laser, is disposed at one end of the detection region. The detection area is then illuminated with a light source. The light source will impinge on each cell in the blood sample to be tested and will be received by the light sensor via refraction, scattering, etc. of each cell. If a light source irradiates each cell, forward scattered light signal data and side scattered light signal data are generated, and the two signal data are used as two-dimensional signal data of the cell particles. If a light source irradiates each cell, three-dimensional signal data is generated, wherein the three-dimensional signal data can be a low-angle scattered light signal, a medium-angle scattered light signal and a high-angle scattered light signal; the low-angle scattered light signal is used for characterizing the volume size of the cell; the medium-angle scattered light signal is used for representing the complexity information inside the cell; the high angle scattered light signal is used to characterize the intracellular particulate information. The three-dimensional signal data may also be forward scatter light signals, side scatter light signals, and side fluorescence signals; forward scattered light signals are used to characterize the cell volume size; the side scattering light signal is used for representing the content information such as particles, cell nucleuses and the like in the cell; the lateral fluorescent signal is used to characterize the intracellular DeoxyriboNucleic Acid (DNA) and Ribonucleic Acid (RNA) content.
By the method, each particle in the sample can be identified and classified according to the acquired signal data.
In some embodiments, the sample to be tested may also be a saliva sample, a urine sample, or the like.
Step 12: and establishing a scatter image, wherein the scatter in the scatter image corresponds to the particles in the sample one by one, and the position of each scatter in the scatter image is determined by the multi-dimensional signal data of the corresponding particle.
In some embodiments, the two-dimensional signal data of the acquired particles is taken as an example for explanation:
if the two-dimensional signal data is forward scattered light signal data and side scattered light signal data, a coordinate system can be established by taking the forward scattered light signal data as an X axis and the side scattered light signal data as a Y axis, and the two-dimensional signal data of the particles detected from the sample to be detected is mapped into the coordinate system to be established into a two-dimensional scatter image.
In some embodiments, the three-dimensional signal data of the acquired particles is taken as an example for explanation:
if the three-dimensional signal data is a low-angle scattered light signal, a medium-angle scattered light signal and a high-angle scattered light signal, the low-angle scattered light signal can be used as an X axis, the medium-angle scattered light signal can be used as a Y axis, the high-angle scattered light signal can be used as a Z axis to establish a space coordinate system, and the three-dimensional signal data of the particles detected from the sample to be detected is mapped into the space coordinate system to establish a three-dimensional scatter image.
Step 13: and adjusting the gray value of each scattered point according to the density of each scattered point in the preset area.
In some embodiments, taking a two-dimensional scatter image as an example, the two-dimensional coordinate system corresponding to the two-dimensional scatter image is divided into a plurality of preset areas a, as shown in fig. 2, the XY axis is divided into a plurality of preset areas a, the density of each scatter point in the corresponding preset area a is calculated, and the density of each scatter point in the corresponding preset area a is obtained. It can be understood that the greater the number of the scattered points in the preset area a, the greater the density thereof, and the gray value of the scattered point is adjusted according to the density. Since the density of each scatter point in each preset area a is the same, the gray value of each scatter point in the preset area a is the same. If there is no scatter in a part of the preset area a, the preset area a is not adjusted.
In an application scenario, there may be a negative correlation between density and gray scale value, with higher densities giving lower gray scale values. In some embodiments, the gray value of the scatter dots having a density lower than the preset density is set to 255.
In some embodiments, taking a three-dimensional scatter image as an example, the three-dimensional coordinate system corresponding to the three-dimensional scatter image is divided into preset regions, and each preset region is a stereo space. And respectively calculating the density of each scatter point in the corresponding preset area, and then obtaining the density of each scatter point in the corresponding preset area A. The number of the preset regions is set according to actual requirements, for example, the preset length of each coordinate axis of the three-dimensional coordinate system is divided into 64 parts, the number of the preset regions is 64 × 262144, and for example, the preset length of each coordinate axis of the three-dimensional coordinate system is divided into 100 parts, the number of the preset regions is 100 × 100 — 10000000. In this embodiment, the number of the preset regions is less than one million, which can reduce the calculation of the sample analysis device on the preset regions, and further increase the calculation amount of the particles corresponding to the scattering points in each preset region, thereby improving the detection efficiency of the sample analysis device.
In an application scenario, the following is explained with reference to fig. 3 and 4: and acquiring sample detection data to obtain three-dimensional signal data corresponding to each particle in the sample. The scatter in the scatter image is in one-to-one correspondence with the particles in the sample, and the position of each scatter in the scatter image is determined according to the three-dimensional signal data of the corresponding particles, thereby creating the scatter image as shown in fig. 3. As shown in fig. 3, the particles corresponding to the more concentrated scatters belong to the same particle type, but there are still many less concentrated particles in fig. 3, and these scatters are referred to as the stray points. And adjusting the gray value of each scattered point according to the density of each scattered point in the preset area. If the gray scale value is set to be lower as the scatter density is higher, the scatter image shown in fig. 3 is set as described above, and the scatter image shown in fig. 4 is formed. It can be seen that, through the above processing, the scatter image shown in fig. 4 increases the gray value of the less dense scatter in the preset area in fig. 3, so that the corresponding pixel becomes white or tends to be white, and the corresponding pixel disappears in visual effect or is distinguished from the scatter group.
After step 13, the adjusted scattergram image is displayed. For example, the sample analysis device may transmit the scatter image to the terminal device over the network to cause a display interface of the terminal device to display the scatter image for viewing by the user. For example, the sample analysis apparatus includes a display screen on which the processed scattergram image is displayed for the user to view after the processing is performed on the scattergram image. In an application scenario, the sample analysis device not only displays the scattergram image on a display screen, but also transmits the scattergram image to a terminal device through a network, so that a display interface of the terminal device displays the scattergram image for a user to view, for example, the terminal device may be a mobile terminal, a PC (Personal Computer) terminal, or the like.
Different from the prior art, the method for displaying a scattered point image in this embodiment includes: acquiring sample detection data to obtain multi-dimensional signal data corresponding to each particle in a sample; establishing a scatter image, wherein the scatters in the scatter image correspond to the particles in the sample one by one, and the position of each scatter in the scatter image is determined by the multi-dimensional signal data of the corresponding particle; and adjusting the gray value of each scattered point according to the density of each scattered point in the preset area. In this way, carry out the grey value setting that corresponds with the scattered point of different densities, can directly perceivedly show the different intensive degree of the scattered point of presetting the region on scattered point image, if according to scattered point density in presetting the region is big more, the grey value of scattered point is lower to be set up, then the scattered point that density is little will darken or disappear, and scattered point image is cleaner and tidier, promotes the display effect of scattered point image, and the user of being convenient for watches, promotes user experience.
Referring to fig. 5, fig. 5 is a flowchart illustrating a method for displaying a scatter image according to a second embodiment of the present disclosure. The method comprises the following steps:
step 51: and acquiring sample detection data to obtain multi-dimensional signal data corresponding to each particle in the sample.
Step 52: and establishing a scatter image, wherein the scatter in the scatter image corresponds to the particles in the sample one by one, and the position of each scatter in the scatter image is determined by the multi-dimensional signal data of the corresponding particle.
Step 53: and acquiring the number of scattered points in the preset area to obtain the frequency distribution of the scattered points in the preset area.
In some embodiments, the scatter image is divided by a coordinate system, if the scatter image is a two-dimensional image, the preset area is a two-dimensional plane area, and the length of the X axis and the length of the Y axis of the preset area are set according to actual requirements. For example, the length of each of the X-axis and the Y-axis is 0.1, 1, 1.5 or 2. And then, acquiring the number of scattered points in each preset area, and further acquiring the frequency distribution of the scattered points in the preset area.
In some embodiments, there is a corresponding particle type for each scatter and the different cell particles are relatively concentrated. When a scatter image is formed, rough area division exists among different types of particles, the area is determined as a first area, then the first area is subjected to preset area division, and the number of scatter points in the preset area is obtained, so that the frequency distribution of the scatter points in the preset area is obtained.
Step 54: and adjusting the gray value of the scattered point in the preset area based on the frequency distribution.
In some embodiments, referring to fig. 6, step 54 may be the following process:
step 541: and obtaining the maximum frequency distribution in the frequency distribution based on the frequency distribution of the scattered points in each preset area.
In some embodiments, since the scatter image is divided into a plurality of preset regions, the scatter in each preset region has a corresponding frequency distribution, that is, at this time, a plurality of frequency distributions exist in the scatter image, and then the maximum frequency distribution is determined from the plurality of frequency distributions.
Step 542: and obtaining the frequency distribution ratio by using the frequency distribution and the maximum frequency distribution.
The frequency distribution ratio can be obtained by dividing the frequency distribution by the maximum frequency distribution, and the frequency distribution ratio of the scatter points in each preset area is correspondingly determined because the scatter point image has a plurality of preset areas.
Step 543: and adjusting the gray value of the scattered point in the preset area based on the frequency distribution ratio.
And adjusting the gray value of the corresponding scatter point in the preset area based on each frequency distribution ratio because the frequency distribution of the scatter point in each preset area correspondingly has one frequency distribution ratio.
In an application scenario, taking a three-dimensional scatter image as an example, the following description is given: the three-dimensional signal data of each particle is respectively recorded as: x (i), y (i), z (i), i ═ 0, 1, 2, …, N. N is the total number of particles. And recording the frequency distribution of the scattered points corresponding to the particles in the three-dimensional space as F, and when the frequency distribution is counted, performing segmentation processing on coordinates of the scattered points corresponding to the three-dimensional signal data of the particles in the three-dimensional space, namely dividing a preset area, wherein the number of the scattered points falling into each preset area is the frequency distribution of the preset area. For example, F (x, y, z) represents the number of scattered points, i.e., the number of particles, which fall within the preset region corresponding to the point (x, y, z), and the number of scattered points is the number of points satisfying the following condition at the same time:
a) x ═ x (i)/DX, i ═ 0, 1, 2, …, N, DX being the length of the predetermined region in x (i);
b) y (y), (i)/DY (i), i (0), 1, 2, …, N, DY being the length of the preset region in y (i);
c) z ═ z (i)/DZ, i ═ 0, 1, 2, …, N, DZ is the length of the predetermined region in z (i).
Then, the maximum frequency distribution in the frequency distributions is determined, and then normalization processing is carried out on each frequency distribution based on the maximum frequency distribution so as to obtain the corresponding frequency distribution ratio. And adjusting the gray value of the scattered point in the preset area according to the frequency distribution ratio. If the proportion of the frequency distribution is larger, the gray value of the scattered point in the preset area is set to be lower. The gray value of the scatter point in the preset area can be set to be 255 if the frequency distribution ratio is lower than the preset ratio.
In some embodiments, the following formula can be used to find the gray value of the scatter point in the preset area.
C(i)＝F(x,y,z)/Fmax*K(T(i))。
Wherein F (x, y, z) represents the frequency distribution of the preset area, and FmaxRepresents the maximum frequency distribution, T (i) represents the particle type, and K (T (i)) represents the empirical parameter corresponding to the particle type T (i). The effect of K (t (i)) is to set different gamma, i.e. weighting coefficients, for different particle types. E.g. for white blood cellsAn image in which when the type of particles denoted by t (i) is monocytes, K (t (i)) is 1.2; when the particle type indicated by t (i) is eosinophil, K (t (i)) is 2.0. It will be appreciated that K (t (i)) may also set different parameters for colour, brightness, etc. for different particle types.
In some embodiments, the particle type corresponding to each scattering point corresponds to a weight coefficient, and after the frequency distribution ratio of the scattering points in each preset area is obtained, the frequency distribution ratio is multiplied by the weight coefficient to obtain the gray value corresponding to the scattering points in the preset area.
In some embodiments, when the frequency distribution of the scatter points in each preset region is obtained through calculation, the frequency distributions are classified according to the particle types corresponding to the scatter points, that is, each particle type corresponds to at least one frequency distribution. The maximum frequency distribution of the at least one frequency distribution of each particle type is determined. And then obtaining the frequency distribution ratio by utilizing at least one frequency distribution of each particle type and the corresponding maximum frequency distribution.
