US Patent 7445599 Ultrasonic cellular tissue screening tool

A system to aid in ultrasound scanning of breast tissue includes a fabric covering, which is adapted to hold the breast tissue in place during scanning, an ultrasonic coupling agent applied to one of the covering or the breast tissue, and a lenticular-shaped pad to cover the nipple of the breast tissue. The pad is placed beneath and held in place by the fabric covering, and the covering is capable of absorbing the coupling agent and conducting ultrasonic energy with minimal interference.
