Measuring Total and Local Changes of Knee Cartilage Volume Using MRI Sequences

Abstract

Degenerative arthritis is a common problem for old people. Many treatments had been develeped and its effect need be assess and validate. Changes in knee cartilage volume in normally adapted the efficacy of treatment. Change in cartilage volumes easurement can be divided into total changes and local changes in knee cartilage volume. The paper focus as the analysis of total cartilage in knee, we developed superimposed tibial side technology for 3D matching and its accuracy is about 90%, we also propose a fast 3D matching technique,which is not only improve the accuracy by 15% but also shorten the execution time of 10% of original. If coupled with the tibial surface to select semi-automatic techniques .it can reduce the operator’s load substantially by 94%.
