Detailed Description
In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a method for acquiring medical diagnostic information according to an embodiment of the present application. In this embodiment, the main execution body of the method for acquiring medical diagnosis information is an electronic device. The electronic device may be the medical device itself for acquiring the first medical image, or may be a device other than a medical device. When the electronic device is other than the medical device, the electronic device and the medical device can perform data communication to realize data interaction between the electronic device and the medical device, control over the medical device and other operations.
The following embodiments are described taking the example that the electronic device is a medical device itself:
as shown in fig. 1, an embodiment of the present application provides a method for acquiring medical diagnostic information, which includes the following steps:
s11: a first medical image acquired by a medical device is acquired, the first medical image including image information of a subject tissue.
In step S11, the medical device is a device capable of image acquisition. For example, an Optical Coherence Tomography (OCT) apparatus.
The first medical image is an image acquired by a medical device comprising tissue of the object after determining the position of the tissue of the object. For example, fig. 2A in fig. 2 is an OCT image of a blood vessel in a human body acquired by an OCT apparatus.
The first medical image is used to show the surface condition of the tissue of the subject. For example, the surface condition of a blood vessel is shown by an OCT image of a blood vessel of a human body, such as a plaque formed on the inner wall surface of the blood vessel due to lipid accumulation is shown by a first medical image.
The subject tissue may be biological tissue in a human or animal. Such as blood vessels or the heart in the human body.
In the present embodiment, a light beam is emitted to a subject tissue by a light source of a medical device so as to obtain a first medical image based on a situation when the light beam irradiates the subject tissue, and therefore, image information of the subject tissue is included in the first medical image so as to describe the subject tissue by the image information of the subject tissue, with the object of determining the subject tissue to be medically diagnosed from the first medical image and providing a basis for data processing based on the first medical image.
The timing for acquiring the first medical image acquired by the medical device may include, but is not limited to, the following two scenarios.
Scene 1: when the medical equipment is detected to acquire a first medical image, the first medical image is acquired.
Scene 2: when the number of the first medical images acquired by the medical equipment reaches a preset image number threshold value, acquiring the first medical images acquired by the medical equipment according to the time sequence of acquiring the first medical images.
The preset image quantity threshold value can be set according to actual requirements.
In some embodiments, in order to improve the efficiency of data processing, when the acquired first medical image is a curved surface image, the first medical image is subjected to dimension reduction processing, and a plan view of the first medical image is obtained.
Preferably, the curved surface view is a three-dimensional view and the plan view is a two-dimensional view.
S12: and inputting the first medical image into the target image synthesis model for processing to obtain a second medical image, wherein the second medical image is used for describing the attenuation degree of the target tissue to the light beam, and the light beam is emitted by a light source used for scanning the target tissue.
In step S12, the attenuation degree is used to describe the situation that when the light beam irradiates the object tissue, the object tissue absorbs part of the energy of the light beam, resulting in attenuation of the light beam.
The light source is a light source disposed on the medical device. For example, a light source arranged in a medical device for emitting X-rays.
In the embodiment, when the light beam irradiates the target tissue, the target tissue absorbs part of energy of the light beam, so that the light beam is attenuated, and therefore the condition of the target tissue can be known based on the attenuation condition of the light beam at each position in the target tissue, in order to know the attenuation degree of the light beam by the target tissue, after the first medical image is acquired, the first medical image is input into the target image synthesis model for image synthesis processing, so as to obtain the second medical image which corresponds to the first medical image and can be used for describing the attenuation degree of the light beam by the target tissue, so that the condition of each position in the target tissue can be known more clearly. For example, the first medical image 2A in fig. 2 is input into the target image synthesis model for processing, resulting in the second medical image 2B.
For example, when a diseased tissue exists in the target tissue, the energy of the absorbed light beam of the diseased tissue may be different from that of other portions in the target tissue, and thus the position of the diseased tissue may be obtained, and medical diagnostic information of the target tissue may be obtained.
It is understood that, in the application, a pre-trained target image synthesis model is stored in the medical device in advance. The target image synthesis model can be trained by medical equipment in advance, and files corresponding to the target image synthesis model can be transplanted to the medical equipment after being trained by other equipment in advance. That is, the subject of execution for training the target image synthesis model may be the same as or different from the subject of execution for image synthesis using the target image synthesis model. For example, when the image synthesis model which is not trained is trained by other equipment, after the training of the image synthesis model which is not trained is finished by other equipment, the model parameters of the image synthesis model which is not trained are fixed to obtain a file corresponding to the target image synthesis model, and then the file is transplanted to the medical equipment.
S13: medical diagnostic information of the subject tissue is acquired from the second medical image.
In step S13, the medical diagnosis information is used to describe whether a lesion appears in the target tissue, and one or more of information such as the location of the lesion, the size of the lesion region, and the type of the lesion.
In this embodiment, since the second medical image is used to describe the attenuation degree of the target tissue to the light beam, whether the target tissue has a lesion or not is known according to the attenuation degree of the target tissue to the light beam at different positions, so as to obtain the medical diagnosis information of the target tissue.
According to the method for acquiring the medical diagnosis information, the first medical image which is acquired by the medical equipment and used for describing the object tissue is acquired, the first medical image is input into the target image synthesis model to be processed, the second medical image which can be used for describing the attenuation degree of the object tissue to the light beam is acquired, the situation that the medical image which can accurately know the situation of the object tissue cannot be acquired due to the problem of system errors of the image imaging equipment can be effectively avoided, the medical diagnosis information of the object tissue is acquired according to the attenuation degree of the object tissue to the light beam recorded in the second medical image, the situation of the object tissue can be accurately known, and treatment of diseases is facilitated.
In some embodiments, after the first medical image is input into the target image synthesis model for processing, and the second medical image is obtained, the second medical image is subjected to image staining processing in order to better understand the condition of the object tissue.
Wherein the second medical image is subjected to a staining process according to a degree of attenuation of the light beam by the object tissue described in the second medical image. Specifically, the second medical image is dyed with a preset color according to different described light attenuation degrees.
For example, a second medical image depicting a blood vessel is stained using a staining strategy of a blue to red to yellow gradient, wherein closer to blue indicates a smaller degree of attenuation, a smaller lipid plaque content of the blood vessel, and closer to yellow indicates a larger degree of attenuation, a larger lipid plaque content of the blood vessel.
In some embodiments, in order to facilitate observation of the tissue of the object, the first medical image and the second medical image are subjected to image fusion processing, and a fused second medical image is obtained.
Specifically, according to the corresponding positions of the pixels of the first medical image and the second medical image, the pixel values in the first medical image are converted into attenuation degree values, and thus a fused image is obtained.
In an embodiment of the present application, with reference to fig. 3, the acquiring medical diagnostic information of the tissue of the subject according to the second medical image includes:
s21: and performing linear interpolation on the coordinate information of the pixel points in the second medical image to obtain the interpolated second medical image.
S22: and projecting the interpolated second medical image to a polar coordinate to obtain a third medical image, wherein the third medical image comprises a plurality of lines of attenuation degree values, each line of attenuation degree values corresponds to one light beam, and each line of attenuation degree values is used for indicating the attenuation degree of the object tissue to the light beam corresponding to each line of attenuation degree values.
S23: medical diagnostic information of the subject tissue is acquired from the third medical image.
In the present embodiment, the attenuation degree value is used to describe the degree of attenuation of the light beam by the tissue point of the target tissue in the irradiation direction of the light beam when the light beam irradiates the target tissue. Therefore, it can be understood that, by each column of attenuation degree values, the attenuation degree of the light beam corresponding to each column of attenuation degree values by the object tissue can be described.
In this embodiment, in order to better process the second medical image, linear interpolation is performed on the coordinate information of each pixel point in the second medical image to obtain the coordinate information of each pixel point of the second medical image in the polar coordinate, and the interpolated second medical image is obtained based on the coordinate information of each pixel point in the polar coordinate. Furthermore, the interpolated second medical image is projected to the polar coordinate to obtain a third medical image, so that the distribution of a plurality of lines of attenuation degree values included in the third medical image in the polar coordinate can be better utilized to quickly know whether each attenuation degree value describing the object tissue is abnormal or not, or the abnormal attenuation degree value is distributed at the position of the third medical image, or the area occupied by the abnormal attenuation degree value, and further the medical diagnosis information of the object tissue can be obtained.
It can be understood that, in order to determine the coordinate information of each pixel point of the second medical image in the polar coordinate, for each pixel point, the relationship between the pixel point and the adjacent pixel point is utilized, and the coordinate of the pixel point is interpolated based on a preset difference algorithm to obtain the coordinate information of the pixel point after interpolation, and then the second medical image is projected to the polar coordinate based on the interpolated coordinate information corresponding to each pixel point, so as to obtain the third medical image in the polar coordinate.
The second medical image is used for describing the attenuation degree of the object tissue to the plurality of light beams, each light beam corresponds to a plurality of tissue points in the object tissue, and each tissue point can absorb the energy of the light beam, so that the attenuation degree of each tissue point to the light beam can be recorded in the second medical image, the attenuation degree of the tissue point to the light beam is recorded through the attenuation degree values corresponding to the pixel points and the pixel points, and the attenuation degree of the tissue point to the light beam of the object tissue can be recorded in the interpolated second medical image corresponding to the second medical image. Furthermore, after the third medical image is obtained by projection based on the interpolated second medical image, the attenuation degree of the tissue point of the target tissue to the light beam is recorded in the third medical image, and the third medical image includes a plurality of rows of attenuation degree values because of the plurality of light beams.
The preset difference algorithm may be, but is not limited to, one of a nearest neighbor interpolation algorithm, a bilinear interpolation algorithm, and a bicubic interpolation algorithm, and the specific implementation process may refer to an implementation process of an interpolation algorithm in the prior art, which is not described herein again.
In an embodiment of the present application, with reference to fig. 4, the acquiring medical diagnostic information of the tissue of the subject according to the third medical image includes:
s31: and determining a target vector corresponding to the first medical image, wherein the target vector comprises the maximum attenuation degree value in each column of attenuation degree values in the third medical image.
S32: and determining a target proportion corresponding to the first medical image based on the target vector, wherein the target proportion refers to the proportion of the attenuation degree value larger than the preset attenuation degree value in the target vector.
S33: medical diagnostic information of the subject tissue is determined based on the target ratio.
In this embodiment, when the attenuation degree value is greater than the preset attenuation degree value, it indicates that there is abnormal degree of attenuation of the light by the abnormal tissue in the target tissue, for example, a diseased tissue point in the target tissue may absorb more light energy, so that the degree of attenuation of the light beam by the tissue point is greater than that of other normal tissue points. The preset attenuation degree value can be set according to actual requirements.
The target proportion corresponding to the first medical image is used for describing the proportion occupied by the abnormal attenuation degree value, and the purpose is to determine whether the object tissue described by the first medical image is abnormal through the target proportion, for example, whether a pathological tissue exists in the object tissue is known through the target proportion.
In this embodiment, in order to improve the efficiency of data processing and determine whether an abnormal tissue point exists in the direction irradiated by each beam irradiating the target tissue, the maximum attenuation degree value in each column of attenuation degree values in the third medical image is determined, so as to describe whether each beam irradiates the abnormal tissue point through each maximum attenuation degree value, further obtain a target vector from each maximum attenuation degree value, and describe the condition of the target tissue corresponding to the first medical image through the target vector. Meanwhile, in order to determine whether the target tissue described by the first medical image is abnormal, the proportion of the attenuation degree value larger than the preset attenuation degree value in the target vector is determined, so that the overall condition of the target tissue is determined according to the target proportion, that is, whether the target tissue described by the first medical image has a lesion is determined according to whether the target proportion is larger than the preset proportion, and thus the medical diagnosis information of the target tissue is determined.
In some embodiments, the target proportion corresponding to the first medical image is calculated by the following formula (1):
Figure BDA0003161103330000091
wherein, IPAxRepresenting the target proportion, mu, corresponding to the first medical imagetI.e. the value in the target vector, N (mu)t>x) representing a value of μ greater than a preset attenuation level value xtTotal number of (2), NtotalThe total number of the light beams corresponding to the third medical image, that is, the number of columns included in the third medical image, is represented, and M is a parameter preset for magnifying the calculation result.
In an embodiment of the present application, in conjunction with fig. 5, the number of the first medical images is plural;

s41: and determining a target value according to the target proportion corresponding to each first medical image in the plurality of first medical images, wherein the target value is used for indicating the number of the first medical images of which the corresponding target proportion is larger than the preset proportion in the plurality of first medical images.
S42: and when the target value is larger than the preset value, determining the pathological change information of the target tissue and obtaining the medical diagnosis information of the target tissue.
In the present embodiment, the preset ratio refers to a minimum ratio value for determining whether or not there is an abnormality in the tissue of the subject included in the first medical image. It is understood that when the target ratio is larger than the preset ratio, the attenuation degree of the light beam by the object tissue is also larger than a certain attenuation degree, that is, the object tissue has an abnormality.
The preset numerical value describes the minimum number of the first medical images in which the target proportion is larger than the preset proportion when the lesion tissue exists in the tissue of the diagnosis target. For example, when the length of the lesion is greater than or equal to 4mm, it is determined that the lesion exists in the target tissue, and since the length of the target tissue corresponding to one first medical image is 0.2mm, 20 corresponding first medical images whose target ratio is greater than the preset ratio are required to be combined to determine that the lesion exists in the target tissue.
In order to be able to diagnose the lesion position in the human body or the animal completely and accurately, the number of the first medical images acquired by the medical equipment is multiple, and the target value is determined according to the target proportion corresponding to each first medical image in the multiple first medical images, so as to determine the first medical image of which the corresponding target proportion is greater than the preset proportion from the multiple first medical images, so that the lesion information of the object tissue is obtained by combining the one or more first medical images of which the corresponding target proportion is greater than the preset proportion, thereby obtaining the medical diagnosis information corresponding to the object tissue.
In some embodiments, in order to better determine the lesion information of the subject tissue and obtain the medical diagnosis information of the subject tissue, the test is performed in advance through a test experiment to obtain the preset ratio. For example, a plurality of test medical image samples are obtained in advance, a medical expert marks lesion information in the test medical image samples, then the reference attenuation degree value is changed to confirm a target proportion corresponding to each test medical image sample, and each test medical image sample is distinguished through a reference proportion corresponding to the reference attenuation degree value set each time, so that a distinguishing effect corresponding to the set reference proportion is known, that is, each test medical sample recorded with the lesion information can be distinguished and processed more accurately through the set reference proportion. By analogy, when a reference proportion is determined to meet the actual requirement, the reference proportion is fixed to serve as a preset proportion, and the reference proportion and the corresponding reference attenuation degree value are fixed to serve as a preset attenuation degree value.
In some embodiments, the target value is indicative of a number of consecutive first medical images of the plurality of first medical images for which the corresponding target proportion is greater than a preset proportion.

In this embodiment, in order to better show the condition of the object tissue, an attenuation degree value matrix is constructed and obtained based on the target vector corresponding to each first medical image, and the attenuation degree value matrix is used as a carpet exhibition diagram to show the medical condition of the object tissue through the carpet exhibition diagram.
In this embodiment, since the carpet extension map can be used for the medical condition of the object tissue, and each first medical image in each carpet extension map records a part of the object tissue, and the first medical image with the target proportion larger than the preset proportion describes the region where the lesion occurs in the object tissue, when the object tissue has the lesion, the lesion region in the object tissue can be located based on the position of the first medical image with the target proportion larger than the preset proportion in the carpet extension map, so as to obtain the lesion information of the object tissue and the medical diagnosis information of the object tissue.
It is to be understood that the planar carpet representation is a two-dimensional carpet representation and the curved carpet representation is a three-dimensional curved carpet representation, wherein the planar carpet representation is converted into the three-dimensional curved carpet representation for a more intuitive viewing of the entire object tissue.
Illustratively, in conjunction with fig. 6, the object tissue is a blood vessel, and a planar carpet-out fig. 8A, or a three-dimensional curved carpet-out fig. 8B is generated from the respective first medical images describing the blood vessel.
In an example, when a lesion is determined to be present from the lesion information, a carpet display map is generated.

It can be understood that, in order to know whether there is an abnormality in the target tissue, after acquiring the medical image including the image information of the target tissue by the medical device, the optical hardware test parameters of the medical device need to be measured manually, so as to determine the medical diagnostic information of the target tissue by determining the attenuation degree of the target tissue to the light beam based on the acquired medical image and the optical hardware test parameters of the medical device, which is time-consuming and labor-consuming, therefore, a plurality of sets of training samples are acquired, and the image synthesis model which is not trained is trained based on the plurality of sets of training samples to obtain the target image synthesis model, which aims to directly synthesize the acquired medical image by the target image synthesis model to obtain the medical image capable of describing the attenuation degree of the target tissue to the light beam, and further obtain the medical diagnostic information of the target tissue, therefore, the data processing efficiency is improved, and the situation that medical diagnosis information determined based on the medical image and the optical hardware parameters has errors and is not beneficial to disease diagnosis can be avoided due to errors of the optical hardware parameters of the medical equipment caused by the manufacturing process during the manufacturing of the medical equipment.
It is understood that the first medical image sample in each set of training samples may be acquired based on the same medical device or may be acquired based on different medical devices.
In some embodiments, since hardware parameters of the medical device used for acquiring the first medical image may be different, for each set of training samples, calibration may be performed using optical hardware test parameters of the medical device that acquires the first medical image sample in the training samples, so that the training samples can be distinguished to facilitate a training operation on an unfinished training image synthesis model.
In some embodiments, in practical applications, since the number of the first medical image samples labeled with the lesion information by the expert is small, the training sample size may be expanded by rotating, flipping, adjusting the contrast, and the like, so as to obtain multiple groups of training samples.
In an embodiment of the present application, training an image synthesis model that is not trained based on a plurality of sets of training samples to obtain a target image synthesis model includes:
and extracting a group of training samples from the plurality of groups of training samples according to a specified extraction mode to obtain a training sample group.

Therefore, in order to enable the image synthesis model to synthesize better images, when it is determined that the training end condition is not reached according to the first training result and the second training result, model parameters of the image synthesis model which is not trained are continuously adjusted based on the first image loss information and the second image loss information, and a set of training samples are continuously extracted from a plurality of sets of training samples according to a specified extraction mode to obtain a training sample set, so that model parameters of the image synthesis model which is not trained are continuously adjusted based on the first image loss information and the second image loss information, so that the image synthesis model which is not trained can better perform synthesis processing on input medical images based on the adjusted model parameters, thereby reducing the loss of image information and enabling the synthesized images to be more accurate.

It is understood that, since the first discriminator is used to judge the authenticity of the input image, when the first discriminator is used to judge the authentic second medical image sample, the output result is 1, and when the first discriminator is used to judge the first composite medical image, since the first composite medical image is synthesized and a part of image information may be lost when the first composite medical image is synthesized, so that there may be a certain difference between the first composite medical image and the second medical image sample, the output result of the first discriminator is between 0 and 1. Thus, LossIPACan be used to describe the similarity between the first synthesized medical image and the second medical image sample in the training sample set, and use this as the first training result to characterize the synthesis accuracy of the first synthesizer.
