Abstract

An ultrasound imaging system (10) includes a scan conversion process for converting ultrasound data into a standard display format conversion and can be performed on a personal computer (14) by programming the computer (14) to convert data from polar coordinates to cartesian coordinates suitable for display on a computer monitor. The data is provided from scan head (12) enclosure that houses an array of ultrasonic transducers (18(1)-18(N)) and the circuitry associated therewith, including pulse synchronizer circuitry used in the transmit mode for transmission of ultrasonic pulses and beam forming circuitry used in the receive mode to dynamically focus reflected ultrasonic signals returning from the region of interest being imaged. <IMAGE>
