Patent

CA 2314198

In an ultrasonic diagnosis apparatus, the circuitry is divided into two parts, that is, first and second units which are connected with a cable. The first unit includes a trigger signal generation circuit for generating a trigger signal in response to a command signal, an ultrasonic wave transmitting and receiving circuit including a probe for transmitting ultrasonic waves in response to the trigger signal and receiving reflected ultrasonic waves to generate a reception signal. The cable transmits the reception signal and the trigger signal. The second unit includes a clock signal generation circuit for generating a clock signal in response to the trigger signal transmitted through the cable, and a/d converter for a/d converting the received reflected ultrasonic waves in response to the clock signal to output ultrasonic diagnosis data. A frequency difference detection circuit for detecting a frequency error between the clock signal and a reference frequency signal and a compensating circuit for compensating the ultrasonic diagnostic data to output compensated ultrasonic diagnostic data may be further provided.
