AI Technical Summary

Problems solved by technology

Conventional processing software segments bones based on image thresholds. There are metal artifacts in the CT data of patients undergoing hip revision surgery. Metal artifacts cannot be removed by threshold selection and can only be manually edited layer by layer by the user. Manual operations affect the 3D data extraction of the pelvis. Accuracy and Extraction Efficiency
[0005] For the above problems, no effective solution has been proposed

Abstract

The invention discloses a pelvis three-dimensional data extraction method and device. The method comprises the steps of acquiring CT data of a pelvis medical image, wherein the CT data are data to besubjected to three-dimensional data extraction; processing the CT data to obtain a three-dimensional data extraction model; inputting the CT data into a three-dimensional data extraction model; obtaining an output result of the three-dimensional data extraction model; and converting the output result into three-dimensional data corresponding to the CT data. According to the method and the device,the technical problem of relatively low accuracy of the extracted pelvis three-dimensional data due to the fact that metal artifacts in the CT data are removed by adopting manual operation when the pelvis three-dimensional data are extracted in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for extracting three-dimensional data of the pelvis. Background technique [0002] As patients undergoing total hip arthroplasty age and become more active, the number of hip revision surgeries continues to increase. There are many reasons for the failure of primary total hip arthroplasty and the need for hip revision surgery, including infection, wear of the polyethylene liner of the prosthesis, and habitual dislocation of the prosthesis. Periprosthetic osteolysis caused by prosthetic wear debris, which in turn leads to aseptic loosening of the prosthesis, is always the main reason for hip revision surgery. In the face of hip revision after primary hip replacement failure, the surgical strategy and surgical technique for acetabular defect repair and reconstruction are one of the challenges for orthopedic surgeons. [0003] The extraction of three-di...
