Abstract
Ultrasound apparatus for examining tissue in a region of interest in a body comprising a housing having a viewing aperture. An ultrasonic transducer is provided comprised of an array of ultrasonic elements disposed in the viewing aperture. Electrical pulses are supplied to the transducer for transducer excitation to introduce ultrasonic signals into the body for reflection from the tissue in the region of interest. The transducer is capable of converting ultrasonic signals reflected from the tissue within the body to the transducer to provide electrical signals. The electrical signals are gain corrected in accordance with time. In-phase and out-of-phase components of the electrical signals are provided and then digitized. The digitized electrical signals are collected to form one image for a single frame of the tissue in the region of interest in the body from transducer excitations less than thirty-three in number which is then displayed.
