ABSTRACT:
A multi-transducer Doppler ultrasound monitor system is disclosed in which a multiplexed switch is interposed between the ultrasound transducers and a single transmitter and receiver of the type utilized used to drive a single transducer and to process the signal produced by that transducer, respectively. This switch has a plurality of inputs, each of which receives a connection to one of the transducers, and a single output which is connected to the transmitter and receiver, and it is effective to connect each input, in sequence, to the output on a time-shared basis. A track & hold circuit is provided at the output of a demodulator following the receiver. This circuit has a single input and a plurality of outputs, each corresponding to one of the multiplex switch inputs. The track & hold circuit distributes the signal at the output of the demodulator in sequence to each of the circuit outputs. In this manner, a single set of electronics can be utilized for a plurality of transducers.
