Outline of Final Research Achievements

This study developed an air-coupled ultrasound measurement system to evaluate non-contacted and non-destructive inner muscle for rehabilitation. Power of ultrasound wave is strongly reduced at boundary between human body and air. We employed a high-sensitive ultrasound pulsar-receiver, and developed jig with X-Y scanner to measure muscle in rehabilitation. We estimated measurement point of human abdominal region, and we proposed fuzzy inference based transmitted wave detection method from amplitude, frequency and other wave features. In experiment, the method detected the transmitted wave with 11 μs error.
