An ultrasonic diagnostic probe is provided which performs simultaneous ultrasonic imaging and Doppler flow measurement. The Doppler transducer is mounted for rotation by a mechanical assembly, which permits the Doppler beam to be steered during imaging to the point in the body where a flow measurement is to be taken. As the Doppler transducer is rotated, a variable impedance device within the probe is adjusted in correspondence with the transducer rotation so as to provide an indication signal of the direction in which the Doppler beam is being directed.

Steerable Doppler transducer probes

System for printing particular information-bearing symbols corresponding to data emanating from a source comprising: source means capable of generating data in a particular sequence; memory means for storing information-bearing symbols; selection means for selecting particular symbols from said memory means corresponding to data emanating from said source; said selection means ordering said particular symbols in a predetermined sequence for printing; a medium adapted to bear printed information-bearing symbols; and transmitting means for transmitting each of said particular characters from said memory means to said medium.
