Problems solved by technology

However, traditional segmentation methods include filtering, automatic thresholding, morphological processing, etc. It is difficult to accurately distinguish the segmentation boundaries of bones and other tissues through traditional segmentation methods, and there is a problem of low segmentation accuracy; deep learning methods require a large amount of labeled data. To train and test the deep learning model, however, the labeled data of human lower limb bones is difficult to obtain, and there are individual differences in human lower limb bones, and there are still problems of low segmentation accuracy and speed

Abstract

The embodiment of the invention discloses a lower limb skeleton model construction method and device, electronic equipment and a storage medium. The method comprises the following steps: obtaining a sequence of original scanning image frames obtained by conducting continuous scanning on the lower limbs of a human body; according to the human body parts to which the original scanning image frames belong, segmenting the original scanning image frames to form at least two segmented regions corresponding to different human body parts; determining a boundary segmentation strategy according to the human body part corresponding to each segmented region; and according to the boundary segmentation strategy, performing skeleton boundary segmentation on the image frame in the segmentation region. Through the technical scheme of the embodiment of the invention, the technical effect of accurately and quickly constructing the lower limb skeleton model is realized.

Description

technical field [0001] The embodiments of the present invention relate to the field of medical technology, and in particular to a method, device, electronic equipment and storage medium for constructing a skeleton model of a lower limb. Background technique [0002] Artificial knee replacement is one of the important means of treating knee diseases. Before performing artificial knee replacement, it is necessary to fully grasp the morphological and structural characteristics of the patient's lower limb bones. Therefore, in order to accurately extract the features of the human lower limb from the femoral head to the ankle joint area, it is necessary to accurately segment and reconstruct the above bony structures. [0003] Artificial knee arthroplasty usually acquires bone data of the lower limbs through sequential medical images collected by computerized tomography (CT). However, due to the inclusion of thousands of CT images, manual segmentation of bone structures is diffic...
