A Hybrid Technique for Automatic Quantification of the Hip Joint Cartilages in MR Images
スポンサーリンク
概要
- 論文の詳細を見る
Quantification of the hip acetabular and femoral cartilages is clinically important. An automatic multi-step technique is proposed to segment the femoral head and acetabular cartilages using clinically obtained multi-slice Tl-weighted MR data. We develop an approach for bone segmentation that employs a modified vector quantization technique. Then, segmented articular space is used to segment the acetabular and femoral head cartilages from each other. Finally, we visualize the cartilage applying the maximum intensity projection. The techniques are implemented in C++ and Matlab programming languages. The feasibility of the proposed techniques is successfully evaluated in the presence of 20 hips including 1200 MR images.
