Ultrasonic body scanner and method

摘要

Non-destructive testing with ultrasonic energy is performed by scanning a focused ultrasound beam until a region of interest is detected and rescanning this region with the beam focused at a plurality of depths. Apparatus for ultrasonic body scanning for medical purposes may include an actively driven transducer crystal which may be dynamically focused. A beam of energy produced by the transducer will be coupled to the patient by a liquid path and a movable mirror may be interposed along the liquid path to cause scanning of the beam.
