Abstract

This paper proposes a muscular thickness measurement method using acoustic velocity dependency according to temperature. It is known that the acoustic velocity for temperature change depends on the materials is slower than warm ones. From this principal, we measured the muscular thickness. We employ a 1.0 MHz ultrasonic probe, and acquire two kind ultrasonic echoes from same position of body with temperature variation. From these echoes, we extract boundary surface echoes. From echoes, regions of muscular and fat are extracted by difference between the acoustic velocity-temperature characteristics of muscular and fat. In our experiment, we employ a piece of pork as an experimental phantom, and we acquire ultrasonic echoes reflected from the phantom. Our proposed method successfully measured the thicknesses in muscular and fat region.
