Description

Technical Field

[0001] This invention relates to the field of medical information, and more specifically, to a method and system for technical evaluation of chest X-ray images. Background Technology

[0002] Chest X-rays are one of the most common imaging examinations. Due to the large workload involved, radiologists may overlook cases where chest X-ray quality is substandard due to various factors, affecting subsequent diagnostic imaging. Therefore, image quality should be assessed first during diagnostic imaging. However, in practice, evaluating image quality one by one is time-consuming, and radiologists often lack sufficient attention or experience in technical assessment, leading to missed or misdiagnosed important lesions. This not only results in low diagnostic efficiency but also affects diagnostic quality. While existing technologies utilize AI to assist in assessing chest X-ray quality, the assessment factors are not comprehensive, leading to inaccurate quality results. Furthermore, the output is only a pass / fail result; radiologists do not know where the defects are. This makes it difficult to improve radiologists' scanning techniques. Therefore, there is an urgent need to develop an AI-assisted tool for comprehensive and intelligent assessment of chest X-ray quality. Summary of the Invention

[0003] In view of this, the main objective of the present invention is to provide a method and system for evaluating chest X-ray images, which can solve the problems of incomplete detection of chest X-ray image quality and the inability of radiographers and radiologists to understand various defects in the images in the prior art.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Example 1

[0033] Figure 1 A flowchart of a chest X-ray technical evaluation method according to Embodiment 1 of the present invention is shown; as follows: Figure 1 As shown, the method includes the following steps:

[0034] Step S101: Receive the patient's DICOM image and define the DICOM image that meets the preset conditions as the first image;

[0035] The preset condition is to determine the qualification of a DICOM image based on its properties, which are evaluated based on whether they match the examination items registered with RIS. If the examination items match the image properties, the first image is output, and the identification result is returned to the corresponding control of "Examination Items" in "Technical Evaluation" of the chest X-ray structured report. This first image is a chest X-ray image (anteroposterior view) used for subsequent AI model diagnosis. If the examination items do not match the image properties, the AI ​​diagnosis process is terminated, a prompt message is sent for relevant personnel to handle, and the result is recorded in the database.

[0036] The tool used in this step is a program.

[0037] Step S102: Input the first image into the chest imaging segmentation model to obtain the chest imaging region;

[0038] The chest imaging region is used for subsequent structural segmentation.

[0039] The tool used in this step is a program.

[0040] Step S103: Input the first image into a plurality of segmentation models for image segmentation, and obtain corresponding segmentation data based on the chest imaging region;

[0041] The segmentation models can include thoracic vertebrae and clavicle segmentation models, rib segmentation models, posterior tracheal spinous processes segmentation models, costophrenic angle and cardiac silhouette segmentation models, subdiaphragmatic lung fields and diaphragm segmentation models, and external obstruction segmentation models. These models are designed based on the characteristics of the chest structure through anatomical segmentation and then trained. The size of the model depends entirely on the anatomical location. Using these models to segment chest X-ray films, the following segmentation data was obtained:

[0042] Thoracic vertebrae and clavicle segmentation model: T1 to T12 vertebral bodies (T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12 vertebral bodies) region, right clavicle region, left clavicle region;

[0043] Rib segmentation model: Right anterior ribs 1 to 7 (Right 1st anterior rib, Right 2nd anterior rib, Right 3rd anterior rib, Right 4th anterior rib, Right 5th anterior rib, Right 6th anterior rib, Right 7th anterior rib) region; Right posterior ribs 1 to 12 (Posterior posterior rib 1, Posterior posterior rib 2, Posterior posterior rib 3, Posterior posterior rib 4, Posterior posterior rib 5, Posterior posterior rib 6, Posterior posterior rib 7, Posterior posterior rib 8, Posterior posterior rib 9, Posterior posterior rib 10, Posterior posterior rib 11, Posterior posterior rib 12) region. The area includes the left anterior ribs 1 to 7 (left anterior rib 1, left anterior rib 2, left anterior rib 3, left anterior rib 4, left anterior rib 5, left anterior rib 6, left anterior rib 7) and the left posterior ribs 1 to 12 (left posterior rib 1, left posterior rib 2, left posterior rib 3, left posterior rib 4, left posterior rib 5, left posterior rib 6, left posterior rib 7, left posterior rib 8, left posterior rib 9, left posterior rib 10, left posterior rib 11, left posterior rib 12).

[0044] Segmentation model of the posterior tracheal spinous process: the spinous process region behind the trachea;

[0045] Costophrenic angle and cardiac silhouette segmentation model: right costophrenic angle region, left costophrenic angle region, cardiac silhouette region;

[0046] Segmentation model of the subdiaphragmatic lung field and diaphragm: right subdiaphragmatic lung field region, left subdiaphragmatic lung field region, right diaphragmatic region, left diaphragmatic region;

[0047] External occlusion segmentation model: high-density regions on the body surface.

[0048] Step S104: Based on the segmentation data and / or chest imaging region, determine the image quality of the DICOM image from different dimensions, and output the qualitative judgment data for each dimension;

[0049] The process of judging the image quality of DICOM images from different dimensions includes: acquiring segmentation data and / or chest imaging regions associated with each dimension, defining the segmentation data and / or chest imaging regions associated with each dimension as associated data; judging whether the associated data meets the judgment conditions based on the preset judgment conditions for each dimension, and outputting qualitative judgment data.

[0050] The dimensions include: determining whether the imaging range is complete, determining whether the imaging position is correct, determining whether the inhalation level is appropriate, determining whether the exposure conditions are suitable, and determining whether there are external obstructions.

[0051] Step S105: Input the qualitative judgment data into the structured report of the chest X-ray and automatically generate the technical assessment content.

[0052] Among them, the dimension for determining whether the imaging range is complete includes: obtaining the associated data of this dimension, namely: chest imaging area, right costophrenic angle area, left costophrenic angle area, right 1st posterior rib area, left 1st posterior rib area, right 7th anterior rib area, right 7th posterior rib area, left 7th anterior rib area, and left 7th posterior rib area.

[0053] If the ribs closest to the upper boundary of the chest imaging area are the first posterior rib region on the right side and the first posterior rib region on the left side, then the upper boundary of the imaging range is considered complete; otherwise, the upper boundary is considered incomplete.

[0054] If the right 7th posterior rib region and the right 7th anterior rib region in the chest imaging area are connected, then the right boundary of the imaging range is considered complete; otherwise, the right boundary is considered incomplete.

[0055] If the left 7th posterior rib region and the left 7th anterior rib region in the chest imaging area are connected, then the left boundary of the imaging range is considered complete; otherwise, the left boundary is considered incomplete.

[0056] If the right costophrenic angle and the left costophrenic angle are visible in the chest imaging area, the lower boundary of the imaging range is considered complete; otherwise, the lower boundary is considered incomplete.

[0057] At this point, the qualitative judgment data is whether the illumination range is complete or incomplete.

[0058] When the projection area is complete, the qualitative judgment data is returned to the "Technical Assessment" and "Projection Area Complete" controls in the chest X-ray structured report;

[0059] If the projection area is incomplete, return the result to the "Technical Assessment" and "Incomplete Projection Area" controls in the structured report of the chest X-ray.

[0060] Among them, the dimension for determining whether the projection position is correct includes: obtaining the associated data of this dimension, namely: chest imaging area, spinous process area behind the trachea, right clavicle area, left clavicle area, right 1st to 10th posterior rib area (right 1st posterior rib, right 2nd posterior rib, right 3rd posterior rib, right 4th posterior rib, right 5th posterior rib, right 6th posterior rib, right 7th posterior rib, right 8th posterior rib, right 9th posterior rib, right 10th posterior rib) area, left 1st to 10th posterior rib area (left 1st posterior rib, left 2nd posterior rib, left 3rd posterior rib, left 4th posterior rib, left 5th posterior rib, left 6th posterior rib, left 7th posterior rib, left 8th posterior rib, left 9th posterior rib, left 10th posterior rib) area;

[0061] If the ratio of the distance between the fitted center line of the spinous process region behind the trachea and the inner edge of the right clavicular region and the inner edge of the left clavicular region is within the first preset value, then the projection position is judged to be correct; otherwise, the projection position is judged to be incorrect.

[0062] The first preset value is 0.9-1.1, that is, if the ratio of the distance between the center line fitted to the spinous process region behind the trachea and the inner edge of the right clavicular region and the inner edge of the left clavicular region is between 0.9 and 1.1, the projection position is judged to be correct; otherwise, the projection position is judged to be incorrect.

[0063] If the ratio of the distance between the fitted center line of the spinous process region behind the trachea and the center line of the right 1st to 10th posterior rib region and the center line of the left 1st to 10th posterior rib region is within the second preset value, the imaging position is judged to be correct; otherwise, the imaging position is judged to be incorrect.

[0064] The second preset value is 0.9-1.1, that is, if the ratio of the distance between the fitted center line of the spinous process region behind the trachea and the center line of the right 1st to 10th posterior rib region and the center line of the left 1st to 10th posterior rib region is between 0.9 and 1.1, the imaging position is judged to be correct; otherwise, the imaging position is judged to be incorrect.

[0065] At this point, the qualitative judgment data is whether the projection position is correct or incorrect.

[0066] When the imaging position is correct, the qualitative judgment data is returned to the "Technical Assessment" and "Correct Imaging Position" controls in the chest X-ray structured report;

[0067] If the projection position is incorrect, the result will be returned to the "Technical Assessment" and "Incorrect Projection Position" controls in the structured report of the chest X-ray.

[0068] Among them, the dimension for judging whether the degree of inhalation is appropriate includes: obtaining the associated data of this dimension, namely: chest imaging area, right clavicle area, left clavicle area, right diaphragm area, left diaphragm area, right subdiaphragmatic lung field area, left subdiaphragmatic lung field area, right 5th anterior rib area, left 5th anterior rib area, right 7th anterior rib area, and left 7th anterior rib area.

[0069] Judging the degree of inhalation:

[0070] If the diaphragm is above the 5th anterior rib at the center line of the clavicle, it indicates inspiratory insufficiency; if the diaphragm is between the 5th and 7th anterior ribs at the center line of the clavicle, it indicates adequate inspiration; if the diaphragm is below the 7th anterior rib at the center line of the clavicle, it indicates hyperinspiration; or if the distance between the highest point of the diaphragm and the lower edge of the lung field formed by the diaphragm and the lower part of the area is less than 1.5 cm, it indicates hyperinspiration.

[0071] Specifically:

[0072] If the center line of the right clavicle region and the right diaphragm region are above the right 5th anterior rib region, and the center line of the left clavicle region and the left diaphragm region are above the left 5th anterior rib region, it is judged as insufficient inspiration.

[0073] The right clavicle region center line and the right diaphragm region are located between the right 5th anterior rib region and the right 7th anterior rib region, and the left clavicle region center line and the left diaphragm region are located between the left 5th anterior rib region and the left 7th anterior rib region, indicating that the degree of inhalation is appropriate.

[0074] The center line of the right clavicle region and the right diaphragm region are located below the right 7th anterior rib region, and the center line of the left clavicle region and the left diaphragm region are located below the left 7th anterior rib region, indicating excessive inhalation.

[0075] The area formed by the left diaphragm region and the left subdiaphragmatic lung field region is defined as the first region, and the area formed by the right diaphragm region and the right subdiaphragmatic lung field region is defined as the second region. When the distance from the highest point of the left diaphragm region to the lower edge of the first region is within the third preset value range, and the distance from the highest point of the right diaphragm region to the lower edge of the second region is within the third preset value range, it is judged as excessive inhalation.

[0076] The third preset value is less than 1.5 centimeters.

[0077] At this point, the qualitative judgment data is whether the degree of inhalation is appropriate, insufficient, or excessive.

[0078] When the inhalation level is appropriate, the qualitative judgment data is returned to the "Technical Assessment" and "Appropriate Inhalation Level" controls in the structured chest X-ray report;

[0079] If the inspiratory depth is insufficient, the result is returned to the "Technical Assessment" and "Insufficient Inspiratory Depth" controls in the structured report of the chest X-ray.

[0080] If the inhalation is excessive, the result is returned to the "Technical Assessment" and "Excessive Inhalation" controls in the structured chest X-ray report.

[0081] Among them, the dimension for determining whether the exposure conditions are appropriate includes: obtaining the associated data of this dimension, namely: chest imaging area, cardiac shadow area, left diaphragm area, and the area of ​​T6 to T12 vertebral bodies (T6 vertebral body, T7 vertebral body, T8 vertebral body, T9 vertebral body, T10 vertebral body, T11 vertebral body, T12 vertebral body).

[0082] If the T6 to T12 vertebral bodies in the area behind the cardiac silhouette are clearly visible, the exposure conditions are considered appropriate; otherwise, the exposure conditions are considered insufficient.

[0083] If lung markings are visible in the area behind the cardiac silhouette, the exposure is considered appropriate; otherwise, the exposure is considered insufficient.

[0084] If the line connecting the left diaphragm region to the left edge of the T6 to T12 vertebral body region intersects, the exposure conditions are considered suitable; otherwise, the exposure conditions are considered insufficient.

[0085] At this point, the qualitative judgment data indicates whether the exposure conditions are suitable or insufficient.

[0086] When the exposure conditions are appropriate, the qualitative judgment data will be returned to the "Technical Assessment" and "Appropriate Exposure Conditions" controls in the structured report of the chest X-ray.

[0087] If the exposure conditions are insufficient, the result will be returned to the "Technical Assessment" and "Insufficient Exposure Conditions" controls in the structured report of the chest X-ray.

[0088] Among them, the dimension for determining the presence of external obstructions includes: obtaining the associated data of this dimension, namely: chest imaging area and high-density area of ​​body surface;

[0089] If the area of ​​the high-density region on the body surface is within the fourth preset value range (e.g., the area is less than the threshold), it is judged that there is no external obstruction; otherwise, it is judged that there is an external obstruction.

[0090] At this point, the qualitative judgment data is either no external shielding or external shielding.

[0091] When there is no external obstruction, the qualitative judgment data is returned to the "Technical Assessment" and "No External Obstruction" controls in the structured report of the chest X-ray.

[0092] When there is an external obstruction, return the result to the "Technical Assessment" "With External Obstruction" control in the structured report of the chest X-ray.

[0093] The following illustration demonstrates poor DICOM image quality and insufficient air intake.

[0094] Figure 2 A schematic diagram of a chest X-ray image in the chest X-ray technical evaluation method according to Embodiment 1 of the present invention is shown.

[0095] Figure 3 A schematic diagram of the chest imaging region segmented by the model in the chest X-ray technical evaluation method according to Embodiment 1 of the present invention is shown.

[0096] Figure 4 This diagram illustrates the segmentation of the clavicle region in the chest X-ray technical evaluation method according to Embodiment 1 of the present invention.

[0097] Figure 5 This diagram illustrates the segmentation of the rib region in a chest X-ray technical evaluation method according to Embodiment 1 of the present invention.

[0098] Figure 6 This diagram illustrates the segmentation of the diaphragm region in a chest X-ray technical evaluation method according to Embodiment 1 of the present invention.

[0099] like Figure 2-6 The diagram shows the imaging areas of the chest, clavicle, ribs, and diaphragm. The DICOM image quality is poor, indicating insufficient inspiration. Specifically, when the diaphragm is above the 5th anterior rib at the midclavicular line, it is considered insufficient inspiration.

[0100] The following illustration demonstrates poor DICOM image quality due to external obstructions.

[0101] Figure 7 A schematic diagram of a chest X-ray image in the chest X-ray technical evaluation method according to Embodiment 1 of the present invention is shown.

[0102] Figure 8 This diagram illustrates the segmentation of high-density areas on the body surface in a chest X-ray technical evaluation method according to Embodiment 1 of the present invention.

[0103] like Figure 7-8 As shown, the model segments high-density regions on the body surface, and if the area is greater than the threshold, it is determined that there is an obstruction outside the body.

[0104] This invention applies AI models and rule-based programs to the technical evaluation of chest X-ray images. After image segmentation of the chest X-ray, segmentation data is acquired. Using this data, the image quality of the chest X-ray is comprehensively and accurately assessed from five dimensions: whether the projection area is complete, whether the projection position is correct, whether the degree of inspiration is appropriate, whether the exposure conditions are suitable, and whether there are external obstructions. The judgment results are automatically fed back into the structured chest X-ray report, automatically generating technical evaluation content, which improves the efficiency and accuracy of radiologists in writing reports. At the same time, the judgment results of each dimension are fed back into the corresponding controls in the structured chest X-ray report, providing timely alerts for abnormalities in chest X-ray imaging techniques, which greatly helps to improve the scanning techniques of radiologists in the future.

[0107] Image filtering module 10 is used to receive DICOM images of patients and define the DICOM images that meet preset conditions as first images;

[0108] The preset condition is to determine the qualification of a DICOM image based on its properties, which are evaluated based on whether they match the examination items registered with RIS. If the examination items match the image properties, the first image is output, and the identification result is returned to the corresponding control of "Examination Items" in "Technical Evaluation" of the chest X-ray structured report. This first image is a chest X-ray image (anteroposterior view) used for subsequent AI model diagnosis. If the examination items do not match the image properties, the AI ​​diagnosis process is terminated, a prompt message is sent for relevant personnel to handle, and the result is recorded in the database.

[0109] The tool used in this step is a program.

[0110] The first data acquisition module 20 is used to input the first image into the chest imaging segmentation model to obtain the chest imaging region;

[0111] The chest imaging region is used for subsequent structural segmentation.

[0112] The tool used in this step is a program.

[0113] The second data acquisition module 30 is used to input the first image into a plurality of segmentation models for image segmentation, and obtain corresponding segmentation data based on the chest imaging region.

[0114] The segmentation models can include thoracic vertebrae and clavicle segmentation models, rib segmentation models, posterior tracheal spinous processes segmentation models, costophrenic angle and cardiac silhouette segmentation models, subdiaphragmatic lung fields and diaphragm segmentation models, and external obstruction segmentation models. These models are designed based on the characteristics of the chest structure through anatomical segmentation and then trained. The size of the model depends entirely on the anatomical location. Using these models to segment chest X-ray films, the following segmentation data was obtained:

[0115] Thoracic vertebrae and clavicle segmentation model: T1 to T12 vertebral bodies (T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12 vertebral bodies) region, right clavicle region, left clavicle region;

[0116] Rib segmentation model: Right anterior ribs 1 to 7 (Right 1st anterior rib, Right 2nd anterior rib, Right 3rd anterior rib, Right 4th anterior rib, Right 5th anterior rib, Right 6th anterior rib, Right 7th anterior rib) region; Right posterior ribs 1 to 12 (Posterior posterior rib 1, Posterior posterior rib 2, Posterior posterior rib 3, Posterior posterior rib 4, Posterior posterior rib 5, Posterior posterior rib 6, Posterior posterior rib 7, Posterior posterior rib 8, Posterior posterior rib 9, Posterior posterior rib 10, Posterior posterior rib 11, Posterior posterior rib 12) region. The area includes the left anterior ribs 1 to 7 (left anterior rib 1, left anterior rib 2, left anterior rib 3, left anterior rib 4, left anterior rib 5, left anterior rib 6, left anterior rib 7) and the left posterior ribs 1 to 12 (left posterior rib 1, left posterior rib 2, left posterior rib 3, left posterior rib 4, left posterior rib 5, left posterior rib 6, left posterior rib 7, left posterior rib 8, left posterior rib 9, left posterior rib 10, left posterior rib 11, left posterior rib 12).

[0117] Segmentation model of the posterior tracheal spinous process: the spinous process region behind the trachea;

[0118] Costophrenic angle and cardiac silhouette segmentation model: right costophrenic angle region, left costophrenic angle region, cardiac silhouette region;

[0119] Segmentation model of the subdiaphragmatic lung field and diaphragm: right subdiaphragmatic lung field region, left subdiaphragmatic lung field region, right diaphragmatic region, left diaphragmatic region;

[0120] External occlusion segmentation model: high-density regions on the body surface.

[0121] The image quality assessment module 40 is used to assess the image quality of the DICOM image from different dimensions based on segmentation data and / or chest imaging region, and output qualitative assessment data for each dimension.

[0122] The data feedback module 50 is used to input qualitative judgment data into the structured report of chest X-ray and automatically generate technical assessment content.

[0123] This invention applies AI models and rule-based programs to the technical evaluation of chest X-ray images. After image segmentation of the chest X-ray, segmentation data is acquired. Using this data, the image quality of the chest X-ray is comprehensively and accurately assessed from five dimensions: whether the projection area is complete, whether the projection position is correct, whether the degree of inspiration is appropriate, whether the exposure conditions are suitable, and whether there are external obstructions. The judgment results are automatically fed back into the structured chest X-ray report, automatically generating technical evaluation content, which improves the efficiency and accuracy of radiologists in writing reports. At the same time, the judgment results of each dimension are fed back into the corresponding controls in the structured chest X-ray report, providing timely alerts for abnormalities in chest X-ray imaging techniques, which greatly helps to improve the scanning techniques of radiologists in the future.

[0127] The result determination unit 404 is used to determine whether the associated data meets the judgment conditions based on the preset judgment conditions for each dimension, and output qualitative judgment data.

[0134] If the right costophrenic angle and the left costophrenic angle are visible in the chest imaging area, the lower boundary of the imaging range is considered complete; otherwise, the lower boundary is considered incomplete.

[0135] At this point, the qualitative judgment data is whether the illumination range is complete or incomplete.

[0136] When the projection area is complete, the qualitative judgment data is returned to the "Technical Assessment" and "Projection Area Complete" controls in the chest X-ray structured report;

[0139] If the ratio of the distance between the fitted center line of the spinous process region behind the trachea and the inner edge of the right clavicular region and the inner edge of the left clavicular region is within the first preset value, then the projection position is judged to be correct; otherwise, the projection position is judged to be incorrect.

[0140] The first preset value is 0.9-1.1, that is, if the ratio of the distance between the center line fitted to the spinous process region behind the trachea and the inner edge of the right clavicular region and the inner edge of the left clavicular region is between 0.9 and 1.1, the projection position is judged to be correct; otherwise, the projection position is judged to be incorrect.

[0141] If the ratio of the distance between the fitted center line of the spinous process region behind the trachea and the center line of the right 1st to 10th posterior rib region and the center line of the left 1st to 10th posterior rib region is within the second preset value, the imaging position is judged to be correct; otherwise, the imaging position is judged to be incorrect.
