低減衰カプラを装着した10MHz超音波断層法

抄録

The usefulness of 10 MHz high-resolution sonography for superficial lesions of the head and neck was studied, and direct probe scanning was compared with probe scanning with a low-attenuating ultrasonic acoustic coupler. 1) As the acoustic coupler was soft enough to be attached to the skin, we could get a full image of the scanned area. 2) Since the acoustic coupler made the marginal image of the skin clearer, better images of the content and the margin of subcutaneous lesions could be obtained. 3) The ultrasonic acoustic coupler was so fragile, however, that we could not use it in many cases.
