Embodiment 1

[0025] figure 1 A schematic structural diagram of a system for obtaining anatomical parameters of the patella based on an axial X-ray image of the patella according to Embodiment 1 of the present invention is shown; figure 1 As shown, the system includes: image information management module 10, image recognition module 20, image quality judgment module 30, postoperative change judgment module 40, anatomical segmentation module 50, calculation module 60 and structured report module 70, wherein,

[0026] The image information management module 10 is connected to the image recognition module 20, and is used to transmit the DICOM image of the patient to the image recognition module 20 through the DICOM protocol when the patient finishes shooting the patella axial X-ray examination item;

[0027] Wherein, the image information management module is a RIS (Radiology Information System) system.

[0028] The image recognition module 20 is connected with the image information managemen...

Embodiment 2

[0042] figure 2 A schematic structural diagram of a system for obtaining anatomical parameters of the patella based on an axial X-ray image of the patella according to Embodiment 2 of the present invention is shown, as shown in figure 2 As shown, the anatomical segmentation module 50 also includes a first judging unit 502, which is used to judge whether the anatomical label is compliant based on the diagnostic data. The judgment rule is: judging whether the number of connected domains of each anatomical label is within the first preset threshold Within, judge whether the diameter and area of ​​the largest connected domain of each anatomical label are within the second preset threshold, judge whether the spatial position of adjacent anatomical labels is correct, judge the shapes of different anatomical labels, and combine the third judgment result Sent to the structured report module 70; if the anatomical label is compliant, the diagnostic data is sent to the computing module...

Embodiment 3

[0046] image 3 It shows a schematic structural diagram of a system for obtaining anatomical parameters of the patella based on an axial X-ray image of the patella according to Embodiment 3 of the present invention, as shown in image 3 As shown, the calculation module 60 also includes a second judging unit 602, which is used to judge whether it meets the patellar joint osteoarthritis based on the third preset rule, the measured value and the second image, and send the third judging result to the structured report The overall evaluation in module 70 corresponds to the controls.

[0047] If the third judgment result is consistent with patellar joint osteoarthritis, return the qualitative judgment result to the "degenerative" control of the overall assessment in the structured reporting module; if the third judgment result is not consistent with patellar joint osteoarthritis, then Returns qualitative verdict results to the "No Degeneration Seen" control for the overall assessme...

Abstract

The invention provides a system for acquiring patella anatomic parameters based on axial view patella X-ray image. After a patient is subjected to an axial view patella X-ray examination item, an image recognition module recognizes digital imaging and communications in medicine (DICOM) images matched with the examination item; an image quality judgment module analyzes the quality of the DICOM images; a postoperative change judgment module performs postoperative change analysis on qualified DICOM images; an anatomic segmentation module segments patella and femur distal ends on DICOM images without postoperative changes, and anatomic coordinates and anatomic labels are set; a calculation module automatically calculates a measured value of each patella joint; and a structured reporting moduleintegrates all processed data and images, and stores all the processed data and images, and outputs diagnostic images. The invention further discloses a method for acquiring the patella anatomic parameters based on the axial view patella X-ray image. The system and the method can automatically measure all anatomic parameters of the patella joint, and actual measurement traces of shown data on theimages are displayed in a conventional report, so that the credibility of the measured values is improved, and the clinical requirements are met.

Description

technical field [0001] The present invention relates to the field of medical information, and more specifically, to a system and method for acquiring patella anatomical parameters based on an axial X-ray image of the patella. Background technique [0002] Patellofemoral osteoarthritis and patellar dislocation are common diseases in joint surgery, and the prevalence rate of the population based on knee joint X-ray is 28% to 52%. Patellofemoral osteoarthritis and patellar dislocation often co-exist, reciprocal causation. Patellofemoral dislocation is often caused by patellofemoral joint instability due to abnormal anatomical structure and biomechanics of the patellofemoral joint. The abnormal shape of the patellofemoral joint leads to abnormal joint contact area, pressure distribution and mechanical load, which can lead to the occurrence of patellofemoral arthritis. Conversely, structural abnormalities caused by patellofemoral osteoarthritis are also predisposing factors for ...
