Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of syphilis detection, and in particular to a syphilis detection result interpretation method, an interpretation device and an electronic device. BACKGROUND

[0002] RPR (Rapid Plasma Reagin, rapid plasma reagin test) is a commonly used syphilis screening test, which belongs to a non-treponema test (non-specific antibody detection). It detects the presence of antibodies (reagin) produced in response to the release of cardiolipin antigen after infection with syphilis spirochetes in the patient's blood, indirectly determining whether there is syphilis infection. It can detect the presence of antibodies in the early stage of infection, quickly identify possible syphilis infection, and thus perform further diagnosis and treatment as soon as possible to reduce disease transmission. Through RPR detection, infected persons can be detected in a timely manner, reducing the spread of syphilis in the population. In addition, in terms of treatment monitoring, the antibody titer of RPR detection can reflect the activity of syphilis infection, and has important value for the evaluation of treatment effect. The antibody titer of RPR detection can also be used to judge disease recurrence. After treatment, if the RPR test result is positive again or the antibody titer value rises, it may indicate a recurrence of syphilis, and the treatment plan needs to be adjusted in a timely manner.

[0003] Therefore, it is particularly important to accurately interpret the RPR test results. The conventional result interpretation mainly relies on manual interpretation by the test personnel, which has strong subjectivity and different personnel may have different interpretation standards, which can easily lead to inconsistency of the results. Moreover, the accuracy is limited, as it is observed by the naked eye, which can be affected by factors such as the experience of the operator and visual fatigue, leading to the occurrence of false positive and false negative results. The efficiency is relatively low, and when a large number of samples are processed, the work efficiency of manual interpretation is relatively low, and the accuracy can be reduced due to factors such as fatigue. In addition, it requires a high operating environment, and needs to be performed in a suitable environment with sufficient light and no vibration, otherwise it can affect the accuracy of the results.

[0004] Therefore, how to accurately interpret the RPR test results is a problem that needs to be solved in the industry. SUMMARY

[0027] In order to make the purpose, technical solutions and advantages of the present application clearer, the following will combine the drawings in the present application to clearly and completely describe the technical solutions in the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0028] In the embodiments of the present application, "at least one" refers to one or more, and "more" refers to two or more. The association relationship between the associated objects is described, which means that there can be three relationships, for example, A and / or B, which can represent the following three cases: A exists alone, A and B exist together, and B exists alone.

[0029] The following will be described in detail Figures 1 to 9 The syphilis test result interpretation method, interpretation device and electronic equipment of the present application will be described in detail. It should be noted that the execution subject of the syphilis test result interpretation method of the present application can be a controller or a syphilis test result interpretation device. The electronic equipment includes a computer or a server. The following will be described taking the execution subject of the syphilis test result interpretation method as a controller as an example.

[0030] The experimental process of RPR (rapid plasma reagin test) includes: dropping patient serum on a reaction card, and then serially diluting the patient serum to quantitatively detect syphilis.

[0031] It should be noted that the reaction card is a specially designed glass or paper card with a circle.

[0032] As Figure 1 shown, the present application provides a syphilis test result interpretation method. The syphilis test result interpretation method is used for the interpretation of the result of rapid plasma reagin (RPR) test. The syphilis test result interpretation method includes: S100, obtaining an image of the diluted reaction card.

[0033] Optionally, a camera device (such as a camera) can be used to take a picture of the diluted reaction card; the controller obtains the image of the reaction card from the camera device, as Figure 4 shown.

[0034] S200, based on the image of the reaction card at 2 n times dilution and the image of the reaction card at the previous dilution, determining the interpretation result of the reaction card at 2 n times dilution; wherein n is a positive integer greater than 0; In the case that the interpretation result of the reaction card is positive, the image of the reaction card at the next dilution is obtained, and the above steps are repeated until the interpretation result of the reaction card at the next dilution is negative.

[0035] In this embodiment, by using the image at 2 n times dilution and the image of the reaction card at the previous dilution (i.e. at 2 n-1 times dilution), the interpretation result of the reaction card at 2 nThe interpretation results of the reaction card at the times titer can avoid the error of positive and negative judgment caused by the blurred image caused by the influence of the external environment when taking the image from the aspect of image acquisition; from the aspect of samples, individual differences can be eliminated, weak positive or critical samples can be identified, and the risk of misjudgment in interpretation can be reduced. In the case of a positive interpretation result, an image of the reaction card at the next titer is obtained, and the above steps are repeated until the interpretation result of the reaction card at the next titer is negative. This can avoid unnecessary dilution and detection steps, significantly reduce the consumption of reagents, reaction cards and time, and dilute the reaction cards with positive interpretation results again instead of covering the entire range, which is suitable for large-scale screening scenarios. In addition, because no manual interpretation is required, the problems of strong subjectivity, limited accuracy and low efficiency in the manual interpretation of RPR test results by inspectors in the prior art are solved, and the accuracy of the interpretation of test results is improved.

[0036] In one embodiment, at 2 n If the result of the reaction card is positive at the times titer, the controller can obtain the result of the next titer, i.e. n+1 Images of reaction cards at multiple titers; and based on 2 n+1 The image of the reaction card at the titer is the same as 2 n Image of the reaction card at the titer, determine 2 n+1 Interpretation results of reaction cards at multiple titers; In 2 n+1 If the result of the reaction card is negative at the times titer, the controller can directly output the result, i.e. n+1 fold titer negative; In 2 n+1 If the result of the reaction card is positive at the multiple titer, the controller can continue to obtain 2 n+2 Images of reaction cards at multiple titers; and based on 2 n+1 The image of the reaction card at the titer is the same as 2 n+2 Image of the reaction card at the titer, determine 2 n+2 Interpretation results of reaction cards at multiple titers; In 2 n+2 If the result of the reaction card is negative at the times titer, the controller can directly output the result, i.e. n+2 fold titer negative; In 2 n+2 If the result of the reaction card is positive at the multiple titer, the controller can continue to obtain 2 n+3 Repeat the above reading process until the result of the reaction card at the next titer is negative.

[0037] like Figure 2 As shown, in some embodiments, based on 2n the reaction card image under the 2 n times dilution and the reaction card image under the previous dilution, determining the 2 S210, extracting a region of interest of the reaction card image, as Figure 5 shown.

[0038] S220, extracting feature information based on the region of interest, and determining the reaction card interpretation result under the 2 n times dilution.

[0039] In this embodiment, by extracting the region of interest, background interference can be excluded, key reaction areas can be concentrated for analysis, and interpretation accuracy can be improved. By processing the region of interest instead of the entire image, the computational complexity can be reduced, which is suitable for high-throughput detection scenarios.

[0040] In one embodiment, the region of interest of the reaction card image is extracted by using a deep learning semantic segmentation algorithm. It has strong robustness to deformation caused by card tilt or uneven illumination.

[0041] In another embodiment, the region of interest of the reaction card image is extracted by using a circular detection algorithm according to the characteristics of the reagent reaction area being circular. The region of interest is the reagent reaction area. The computational complexity is much lower than that of the deep learning semantic segmentation algorithm, and the real-time processing speed is high. By using prior knowledge such as the radius range and circularity parameters of the reaction area, non-circular artifacts and weak edge reactions can be effectively excluded.

[0042] In one embodiment, high-dimensional features are extracted based on the region of interest, and the reaction card interpretation result under the 2 n times dilution is determined; wherein the high-dimensional features refer to features extracted in a deep learning model.

[0043] As Figure 6 and Figure 7 shown, optionally, the deep learning model is trained based on the following steps: obtaining and inputting historical reaction card images under the 2 n times dilution into the feature extraction structure of an initial deep learning model to obtain first high-dimensional features output by the initial deep learning model; obtaining and inputting reaction card images under the previous dilution into the feature extraction structure of the initial deep learning model to obtain second high-dimensional features output by the initial deep learning model. The first high-dimensional features and the second high-dimensional features are input into the classification structure of the initial deep learning model to obtain the reaction card interpretation result under the 2 n times dilution output by the classification structure of the initial deep learning model.

[0044] According to 2 n The true label of the reaction card interpretation result under the 2-fold dilution updates the model parameters of the initial deep learning model, and a trained deep learning model is obtained.

[0045] The current 2 n Fold dilution reaction card image and the reaction card image under the previous dilution are input into the trained deep learning model, and the 2 n Fold dilution reaction card interpretation result output by the trained deep learning model is obtained.

[0046] Optionally, the network structure of the deep learning model includes a network structure based on a convolutional neural network (Convolutional Neural Network, CNN) or a network structure based on a Transformer. The Transformer is a deep learning model based on an attention mechanism.

[0047] Optionally, the 2 n Fold dilution reaction card interpretation result output by the trained deep learning model includes 0 and 1. Wherein, 0 represents negative, and 1 represents positive.

[0048] In another embodiment, statistical features of image pixels in the region of interest are extracted, and the 2 n Fold dilution reaction card interpretation result is determined; the statistical features include at least one of the gray value variance, contrast, energy, entropy, homogeneity, and area ratio of the condensed region, and / or the statistical features include at least one of the ratio of the gray value variance, the contrast ratio, the energy ratio, the entropy ratio, the homogeneity ratio, and the area ratio of the condensed region of the image pixels under the 2 n Fold dilution and the previous dilution, as shown in Table 1.

[0049] Optionally, the statistical feature refers to a feature obtained by statistical numerical calculation on the pixel value of the region of interest, and the statistical feature includes at least one of the gray value variance, contrast, energy, entropy, homogeneity, and area ratio of the condensed region.

[0050] These statistical features are input into a classification structure, which can be a support vector machine model or a random forest model.

[0051] Optionally, the classification structure can be trained based on the following steps: inputting the calculated first statistical feature and second statistical feature into an initial classification structure model to obtain the 2 n Fold dilution reaction card interpretation result output by the initial classification structure model. Wherein, the first statistical feature is the 2 nThe first statistical feature is a feature obtained by performing statistical numerical calculation on the pixel values ​​of the region of interest of the reaction card at a times titer; the second statistical feature is a feature obtained by performing statistical numerical calculation on the pixel values ​​of the region of interest of the reaction card at a previous titer; According to 2 n The actual labels of the reaction card interpretation results at the times titer are used to update the model parameters of the initial classification structure model to obtain a trained classification structure model.

[0052] Set the current 2 n The statistical features corresponding to the reaction card image at the times titer and the reaction card image at the previous titer are input into the trained classification structure model to obtain the 2 output of the trained classification structure model. n The results were interpreted using reaction cards at multiple titers.

[0053] Optionally, the classification structure can also be obtained by training based on the following steps: inputting the calculated first statistical feature, the second statistical feature and the third statistical feature into the initial classification structure model to obtain the output of the initial classification structure model. n The first statistical feature is the interpretation of the reaction card under the titer of 2 times. n The first statistical feature is a feature obtained by performing statistical numerical calculation on the pixel values ​​of the region of interest of the reaction card at the first titer; the second statistical feature is a feature obtained by performing statistical numerical calculation on the pixel values ​​of the region of interest of the reaction card at the previous titer; the third statistical feature is the ratio of the first statistical feature to the second statistical feature, as shown in Table 1.

[0054] According to 2 n The actual labels of the reaction card interpretation results at the times titer are used to update the model parameters of the initial classification structure model to obtain a trained classification structure model.

[0055] Set the current 2 n The statistical features and ratios of the reaction card image at the times titer and the reaction card image at the previous titer are input into the trained classification structure model to obtain the 2 output of the trained classification structure model. n The results were interpreted using reaction cards at multiple titers.

[0056] It should be noted that the first statistical feature includes 2 n At least one of the grayscale value variance, contrast, energy, entropy, homogeneity and area ratio of agglutinated regions of image pixels at a multiple of titer.

[0057] The second statistical feature includes at least one of grayscale value variance, contrast, energy, entropy, homogeneity, and area ratio of agglutinated regions of image pixels at a previous titer.

[0058] The third statistical feature includes 2n at least one of a ratio of a variance of gray scale values of pixels in the current drop and a variance of gray scale values of pixels in the previous drop, a contrast ratio, an energy ratio, an entropy ratio, a homogeneity ratio, and a ratio of an area of the agglutination area.

[0059] The specific extraction process of the statistical characteristics is described below.

[0060] The controller first converts the image into a gray scale image and determines the gray scale value of each pixel.

[0061] The controller can determine the gray scale value of each pixel by using a standard weighted average method in combination with formula (1). .

[0062] Formula (1).

[0063] In formula (1), R represents the pixel value in the red channel, G represents the pixel value in the green channel, and B represents the pixel value in the blue channel.

[0064] The controller can determine the variance of the gray scale values of the region of interest by using formula (2). .

[0065] Formula (2).

[0066] In formula (2), N is the number of pixels, R is the region of interest, and G is the gray scale value of the pixel point.

[0067] The controller determines the contrast based on the gray scale co-occurrence matrix of the region of interest. The contrast can be used to measure the degree of local gray scale change, and the larger the value, the clearer the black precipitate on the reaction card.

[0068] The controller can also determine the energy based on the gray scale co-occurrence matrix of the region of interest. The energy can reflect the uniformity of the gray scale distribution of the image, and the larger the value, the more uniform the texture, i.e., the reaction card is almost a flat background without black precipitate.

[0069] The controller can also determine the entropy based on the gray scale co-occurrence matrix of the region of interest. The entropy is used to describe the randomness of the texture, and the larger the value, the more complex the texture, i.e., the black precipitate is randomly distributed on the slide.

[0070] ​​​​​​​​​​The controller can also determine homogeneity based on the gray level co-occurrence matrix of the region of interest. Homogeneity reflects local gray level similarity, and a large value indicates that the texture is smoother, and the color of the local region is consistent, which is a color consistent background.

[0071] Considering that the distribution of precipitates in the wave plate (i.e., the reaction card) is independent of direction, a symmetric gray level co-occurrence matrix is constructed using equation (3) .

[0072] Equation (3).

[0073] Equation (4).

[0074] In equation (3), d represents the probability of two pixels with a distance of d appearing simultaneously in the image, where one pixel has a gray level value of i and the other pixel has a gray level value of j; In equation (4), and are determined by the distance d and the direction ; M represents the width of the image, N represents the height of the image, and d is usually taken as 1.

[0075] When d = 1, When d = 2, When d = 3, When d = 4, Specifically, the controller can calculate the contrast based on the gray level co-occurrence matrix of equation (3) .

[0076] Specifically, the controller can calculate the energy based on the gray level co-occurrence matrix of equation (3) .

[0077] Specifically, the controller can calculate the homogeneity based on the gray level co-occurrence matrix of equation (3) .

[0078] Optionally, the controller can binarize the grayscale image of the region of interest to determine the area ratio of the aggregation region.

[0079] Specifically, the controller binarizes the grayscale image of the region of interest to distinguish the foreground and the background, where the foreground is the black precipitate of the antigen-antibody reaction, and extracts features of the binarized image.

[0080] The grayscale image is converted to a binarized image, where values greater than a threshold T are 1 and values less than the threshold T are 0.

[0081] First, the grayscale value distribution of all pixels in the region of interest is counted to obtain a histogram H(k).

[0082] Equation (4).

[0083] In equation (4), is the Dirac function. If , then ; else, 。

[0084] The peak value of the histogram is . The peak value refers to the grayscale value with the highest frequency in the histogram.

[0085] The grayscale value with the highest frequency in the grayscale image is that of the background. However, due to uneven lighting during shooting, the grayscale of the background is distributed within a certain range. Therefore, the threshold T can be a function of .

[0086] Considering that the color of the reaction precipitate is generally quite dark, close to black 0, the calculation function of the threshold T can be v on the basis of . Optionally, v can be 20.

[0087] The area ratio of the aggregation region (i.e., the black region) is .

[0088] wherein is the Dirac function. If , then ; else, 。

[0089] Table 1 Statistical characteristics

[0090] like Figure 3 As shown, in some embodiments, if n is greater than a threshold value N, the reading is terminated and the reading result is output. A maximum dilution factor (determined by N) is set to avoid infinite testing due to system errors or anomalies. N can be adjusted according to experimental requirements to balance the detection range and resource consumption.

[0091] Optionally, N can be 8 or 10.

[0092] Optionally, when n is greater than N, the output judgment result is 2 n-1 Positive at a titer of 1.

[0093] like Figure 3 As shown, in some embodiments, when n is 0, the reaction card interpretation result at 1x titer is determined based on the reaction card image at 1x titer and the reaction card image of the negative control sample. By setting n equal to 0, the detection of the original sample is ensured, avoiding missed detections. Using a negative control eliminates systematic errors and improves reliability.

[0094] Optionally, when the result of the reaction card at 1x titer is negative, a negative result at 1x titer is output.

[0095] Optionally, if the result of the reaction card at 1x titer is positive, obtain 2 1 Then, based on the reaction card image of 2 times the titer 1 The reaction card image at the times titer and the reaction card image at the previous titer (i.e. 1 times titer) are used to determine the 2 1 Interpretation results of reaction cards at multiple titers.

[0096] like Figure 3 As shown, in some embodiments, in 2 n If the reaction card is negative at the titer, the reading is terminated and the result is output. If the titer is 1:16 (n=4) and the result is negative, there is no need to test higher dilutions such as 1:32 (n=5) and 1:64 (n=6). 1:8 (n=3) is directly output as the last positive titer.

[0097] Optional, in 2 n If the result of the reaction card under the titer is negative, the output result is 2 n-1 Positive at a titer of 1.

[0098] like Figure 3 As shown, in some embodiments, when the reading result of the reaction card is negative at the latter titer, the output reading result is 2 n Positive at a titer of 1.

[0099] As Figure 8 shown, the second aspect of the present application provides a syphilis test result interpretation device. The interpretation device includes an acquisition module and a determination module; the acquisition module is used to acquire the image of the diluted reaction card; the determination module is used to determine the reaction card interpretation result under the 2 n fold dilution based on the reaction card image under the 2 n fold dilution and the reaction card image under the previous dilution; wherein n is a positive integer greater than 0; in the case of a positive interpretation result, the acquisition module acquires the reaction card image under the next dilution, and the determination module is used to repeat the above steps until the reaction card interpretation result under the next dilution is negative.

[0100] Figure 9 An example of a schematic diagram of the physical structure of an electronic device is shown in Figure 9 , which can include a processor 810, a communications interface 820, a memory 830, and a communications bus 840, wherein the processor 810, the communications interface 820, and the memory 830 communicate with each other through the communications bus 840. The processor 810 can invoke the logical instructions in the memory 830 to execute a syphilis test result interpretation method, which includes: acquiring the image of the diluted reaction card; determining the reaction card interpretation result under the 2 n fold dilution based on the reaction card image under the 2 n fold dilution and the reaction card image under the previous dilution; wherein n is a positive integer greater than 0; in the case of a positive interpretation result, the acquisition module acquires the reaction card image under the next dilution, and the determination module is used to repeat the above steps until the reaction card interpretation result under the next dilution is negative.
