Problems solved by technology

The cruciate ligament includes the anterior cruciate ligament and the posterior cruciate ligament, and the two ligaments are often stuck together in some areas, which also makes it very difficult to separate the two ligaments separately.
Moreover, there is currently no technical solution related to the segmentation of cruciate ligaments in medical images in China
[0004] In summary, the existing cruciate ligament segmentation technology obviously has inconvenience and defects in actual use, so it is necessary to improve it

Embodiment Construction

[0089] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0090] see figure 1 , in the first embodiment of the present invention, a cruciate ligament segmentation system 100 is provided, the system 100 comprising:

[0091] The central point determination module 10 is used to determine the central point set of the cruciate ligament that needs to be divided;

[0092] A calculation module 20, configured to calculate the extraction area of ​​the cruciate ligament according to the central point set of the cruciate ligament;

[0093] The extraction module 30 is configured to extract the cruciate ligament in the extraction area.

[0094] The invention belongs...

Abstract

The invention relates to the field of medical image processing, and provides a cruciate ligament segmentation method and system. The method includes the steps of the center point determination step, wherein a point set of cruciate ligament center point needing segmenting is determined, the calculation step, wherein an extraction region of the cruciate ligament is calculated according to the point set of the cruciate ligament center points, and the extraction step, wherein the cruciate ligament is extracted from the extraction region. Accordingly, a medical image of the cruciate ligament of the knee joint can be segmented.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to a cruciate ligament segmentation method and system thereof. Background technique [0002] The cruciate ligament, also known as the cruciate ligament, is an important stabilizing structure of the knee joint. Cruciate ligament injuries are more common in people's daily sports. Clear imaging of the state of the cruciate ligament before the operation can provide the surgeon with an important basis for the operation and provide a strong guarantee for the smooth progress of the operation. In CT (Computed Tomography, computerized tomography) images, the normal cruciate ligament cannot be visualized, or sometimes it can be faintly visualized in CT images scanned after ligament reconstruction surgery, only in some MRI (Magnetic Resonance Imaging, nuclear magnetic resonance imaging) images. It can be developed more clearly in the image sequence. [0003] In MRI images, ...
