Technique for detecting and evaluating breast lesions.

A sonographic method is described that provides additional information concerning ultrasonic tissue properties. It allows simplified interpretation and eventually might permit automatization. In this technique a totally reflecting plate is used as an indicator for presence of breast lesions because such lesions cause changes of reflectivity, attenuation, and velocity when exposed to ultrasound beams. Twenty-seven benign lesions and 33 malignancies were examined with this method.
