ABSTRACT:
A pad assembly for coupling ultrasound from a transducer probe into the human body includes a shallow receptacle 20 with a removable cover 22 on the upper portion thereof. Within the receptacle are a foam section 14, a gel pad 12 and a thin net section 18. The net section 18 is bonded to the cover 22. The gel pad 12 is impregnated with a mixture of glycerin and water. The upper surface of foam section 14 is convoluted or ribbed so that there is a substantially lower surface tension between the foam section 14 and the gel pad than between the probe and the gel pad. There is also a substantially lower surface tension between net section 18 and the gel pad than between the gel pad and the foam section.
