  • Publication number: 20220211353
    Abstract: To set parameters according to a body part of interest serving as a target for producing a color Doppler image, a processor in an ultrasonic image display system identifies a body part of interest serving as a target for producing a color Doppler image of a patient based on data for a B-mode image, and determines parameters regarding acquisition of data for the color Doppler image according to the body part of interest. The processor then controls an ultrasonic probe to perform a color Doppler scan for a color Doppler image on the patient using the determined parameters, and creates data for a color Doppler image based on echo data obtained by the color Doppler scan.

  • Publication number: 20220167946
    Abstract: A processor in an ultrasonic image display system displays in first and second B-mode images BI1, BI2 a first measured portion M1 and a region R indicating a candidate of a second measured portion M2, and after the first measured portion M1 has been displayed, acquires a result of a first measurement based on echo data obtained by a first measuring scan. Moreover, after the region R has been displayed, the processor stores echo data obtained by a second measuring scan in said memory. After the echo data obtained by the second measuring scan has been stored, once a user interface has accepted an operator's input for defining the second measured portion M2 within the region R, the processor acquires a result of a second measurement based on the echo data stored in the memory.
