Ultrasonic diagnostic apparatus

An ultrasonic diagnostic apparatus comprising:

• a transducer for transmitting an ultrasonic beam into a subject and receiving an ultrasonic echo reflected from inside said subject and converting said received ultrasonic echo into electric echo signals;
• an ultrasonic beam controller providing the ultrasonic beam along a given direction that is also the direction along which the ultrasonic echo reflected from inside the subject is received, said ultrasonic beam being provided and said reflected echo being received within a predetermined time period prior to providing a new ultrasonic beam in a different direction;
• a B-mode ultrasonic image processing portion producing B-mode ultrasonic image data from said electric echo signals converted by said transducer;
• a Doppler signal phase detecting portion having an input receiving said electric echo signals supplied from said transducer and functioning to detect and provide Doppler signals as an output;
• a Doppler signal analyzer responsive to said Doppler signals to determine both blood flow velocity data and tissue motion velocity data within said predetermined time period;
• a display control portion receiving said blood velocity data and said tissue motion velocity data along with B-mode ultrasonic image data and providing first display data as a combination of B-mode ultrasonic data with blood flow velocity data and second display data as a combination of B-mode ultrasonic data with tissue motion velocity data;
• and
• a display controlled by said display control portion to display said first display data and said second display data together.
