Ultrasound senses 'feel' of breast lesions
... and to detect the resulting effects on tissues. A computer
converts the reflections from the tissue into images. Of the two kinds of ultrasound pulses, "tracking" beams are used to monitor motion created by the second kind -- high-energy "pushing" beams. The pushing beams actually displace tissue by tran...
