AI Technical Summary
In knee X-ray images, a tibial mask image that is too short results in a short tibial mask boundary, which affects the automatic detection or determination of the third and fourth boundary lines on both sides of the tibia or tibial cortex.
By determining the mirror lines of the anterior and posterior vertices of the tibial plateau, the tibial mask boundary is mirrored and a tibial mask image is constructed. Using a keypoint detection network and a deep learning segmentation model, the tibial mask boundary is automatically detected, and the third and fourth boundary lines are determined by combining the polar coordinate Hough transform.
It achieves complete restoration of the tibial mask boundary, ensures accurate automatic detection of the boundary lines on both sides of the tibia or tibial cortex, supports the subsequent determination of the tibial midline and femoral midline, and improves the diagnostic and evaluation accuracy of knee X-ray images.
