| Outline of Final Research Achievements |
The purpose of this study was to develop an automated volume scanner system and a computer-aided diagnosis system for ultrasound. This study aims to quantify the condition of the muscle from a ultrasound image.
First, the upper and lower fasciae from the ultrasound image are extracted. They are approximated by curves, and the area between the curves is set as a region of interest (ROI). Next, we calculate texture features and muscle thickness from the ROI. We build a regression model of the knee extension
strength by combining the texture features, the muscle thickness, and physical features. Finally, we substitute the features calculated from the test data into the regression model, and estimate their knee extension strength.
