1. A system for screening cellular tissue, comprising an ultrasound scanning device including an ultrasound probe that is capable of generating image data representing images of cellular tissue; one or more sensors coupled with the probe to determine the probe's location; a viewer to display the image data as images, the viewer providing a rapid sequential display of scan images; a pad to cover the patient's nipple, said pad being ultrasonically conductive and having different ultrasonic characteristics than breast tissue; and a fabric covering for the breast tissue, adapted to hold the breast tissue in place during scanning, wherein the fabric is capable of absorbing an ultrasonic coupling agent, and transmitting ultrasonic energy with minimal interference.
