Ultrasonic diagnostic apparatus

An ultrasonic diagnostic apparatus in which an ultrasonic pulse beam is transmitted into an organism and ultrasonic waves reflected within the organism are received to obtain received signals, this process is repeatedly performed to obtain the received signals, and an image is displayed in accordance with the received signals thus obtained, said ultrasonic diagnostic apparatus comprising:

• a blood flow velocity arithmetic unit for extracting a Doppler transition component of the reflected ultrasonic waves in accordance with the received signals to evaluate a distribution of a velocity of a blood flow within the organism in accordance with the extracted Doppler transition component;
• a blood flow power arithmetic unit for extracting a Doppler transition component of the reflected ultrasonic waves in accordance with the received signals to evaluate a distribution of a power of a blood flow within the organism in accordance with the extracted Doppler transition component;
• and
• an image display unit for simultaneously displaying on a display screen a first image representative of a blood flow velocity distribution evaluated by said blood flow velocity arithmetic unit, and a second image representative of a blood flow power distribution evaluated by said blood flow power arithmetic unit.
