Abstract :
We present a new method of imaging soft tissues that promises to improve the documentation of the size of breast masses. This system makes a series of distributed pressure measurements and averages them into a composite tactile map of the palpable structure. We estimated mass size from tactile maps made in a limited clinical trial. The system proved to be nearly three times as accurate as ultrasound and manual estimates of mass size
