Ultrasonic imaging apparatus for displaying B-mode and Doppler-mode images

摘要

An ultrasonic imaging apparatus includes an ultrasonic transducer for transmitting/receiving a high-frequency ultrasonic wave for obtaining a B-mode image and a low-frequency ultrasonic wave for obtaining a Doppler-mode image, a transmission circuit for driving the ultrasonic transducer in B and Doppler modes so as to output an ultrasonic beam therefrom, a reception circuit for processing a high-frequency echo signal corresponding to the B mode and a low-frequency echo signal corresponding to the Doppler mode, and for outputting a B-mode image signal and a Doppler-mode image signal, and a display circuit for displaying the B- and Doppler-mode image signals from the reception circuit as a tomographic image of an object to be measured and blood flow speed data.
