ABSTRACT:
An ultrasonic diagnosing apparatus comprising, a first transducer array having a plurality of ultrasonic transducers arranged in a given direction for transmitting an ultrasonic beam into a tissue of a human body and for receiving the ultrasonic echo reflected from the tissue, a second transducer array having a plurality of ultrasonic transducers, for transmitting an ultrasonic beam into the tissue and receiving the ultrasonic echo reflected from the tissue, arrayed in a direction orthogonal to the direction of an array of the transducers in said first transducer array and arranged at an acute angle with respect to said first transducer array in a direction along which the ultrasonic beam of said first transducer array is transmitted and the ultrasonic echo is received, a first signal processing circuit for processing the ultrasonic echo received by said first transducer array to produce an output signal corresponding to tomogram information of the tissue, a second signal processing circuit for processing the ultrasonic echo received by said second transducer array to produce an output signal corresponding to a velocity of a blood flow in the tissue, first display means for displaying a tomogram based on the output signal of said first signal processing circuit; and second display means for displaying blood flow information based on the output signal of said second signal processing circuit.
