In the hip joint, the femoral and acetabular cartilages are in proximity to each other, a conventional measurement technique based on the edge detection, can introduce large underestimation errors in measurement of cartilage thickness. In this study, we develop a model-based approach for accurate thickness measurement. We model the imaging process of two adjacent sheet structures, which simulate two...
The purpose of this study is to develop a new method for the registration of 3D cartilage plates in the MR data set. This technique traces local cartilage thickness changes over time. In a first rough registration step, the principal axes transformation (PAX) and landmark methods are used. In the second step, an improved iterative closest point (ICP) method is used. The point sets from segmentation...
