  • Methods and apparatus for the examination and treatment of internal organs
    Patent number: 5257629
    Abstract: The internal examination of a human organ is made by means of an ultrasonic probe inserted into the organ, and in one embodiment analogue echo signals from the probe are directly converted into digital signals before any signal processing is carried out. These signals are then stored in a digital computer where they are manipulated to produce a two-dimensional real-time representation of the interior of the organ for display on a terminal or as hard copy. The two-dimensional real-time image may be displayed simultaneously with a three-dimensional nonreal-time image produced by the system.
