ABSTRACT:
An ultrasonic imaging apparatus comprises an ultrasonic transducer for outputting ultrasonic beams and converting echo waves of the ultrasonic beams to a B-mode echo signal corresponding to a B-mode for obtaining a tomographic image and a D-mode echo signal corresponding to a D-mode for obtaining Doppler data, a transmitter circuit for driving the transducer for generating the ultrasonic beams for scanning a subject, a receiver circuit including a gain control circuit for controlling the gain of the B-mode and D-mode echo signals output from the ultrasonic transducer so that the level of the B-mode echo signal is made to equal to that of the D-mode echo signal and for outputting gain-controlled echo signals, and A/D converter for converting the gain-controlled signals to digital signals, and a delay/addition circuit for delaying the digital signals and adding them to output a received signal, a B-mode processor circuit for producing a B-mode image signal from the received signal, a D-mode processor circuit for producing Doppler data from the received signal, and a display for displaying the B-mode image signal and D-mode data.
