Abstract:
The loss of muscle mass is considered to be a major determinant of
strength loss among elderly population. A study of muscular thickness
measurement method founded on re
ection echo from the boundary surface of the targeted area using ultrasonic wave is presented. By exploring
the traveling direction of ultrasonic wave at the boundary surface of fat-muscle or muscle-fat, phase difference of the generated re
ection echo
can be measured. In the present study, boundary surface is identified
by utilizing the difference of the re
ected echo at frontier surface. Two
different methods of interface echo recognition are introduced. To measure the re
ection echo, ultrasonic waves are irradiated to a biological
phantom using ultrasonic single probe with center frequency of 5.0 MHz.
In an experimental environment, the proposed methods were applied to
a fat-muscle-fat 3-layer phantom and muscle thickness was measured.
In the template based method, the mean absolute error of the thickness
was 0.32 mm, whereas for continuous wavelet transform (CWT) based
method was 0.06 mm. It was observed that the level of the measurement
precision is better in the CWT based method.
