An ultrasonic image display system comprising a display, a processor, memory, and an ultrasonic probe, said processor being adapted to perform control comprising the acts of:
- controlling said ultrasonic probe to perform a B-mode scan for a B-mode image on a patient;
- creating data for a B-mode image based on echo data obtained by said B-mode scan;
- defining a region of interest in said B-mode image;
- controlling said ultrasonic probe to perform a first color Doppler scan for a first color Doppler image on said patient;
- creating data for said first color Doppler image in said region of interest based on echo data obtained by said first color Doppler scan;
- displaying the first color Doppler image on the display;
- identifying a body part of said patient in a first region in said patient based on the data for said B-mode image in said first region, said first region including said region of interest;
- identifying a body part of interest serving as a target in said region of interest in said patient based on the data for said first color Doppler image in a second region constituted by said region of interest, said body part of interest being included in the body part of said patient in said first region;
- determining parameters regarding acquisition of data for a second color Doppler image of said patient according to said body part of interest;
- generating control signals for controlling one or more of the transmitter and the receiver of said ultrasonic probe to further perform a second color Doppler scan on said patient based on the determined parameters;
- creating data for said second color Doppler image based on echo data obtained by said second color Doppler scan;
- and
- displaying said second color Doppler image on the display;
- wherein said memory is configured for storing a first learned model trained for a correlation between a B-mode image and a first evaluation value for said B-mode image, and a second learned model trained for a correlation between a color Doppler image and a second evaluation value for said color Doppler image, said first evaluation value being related to a body part of the patient, said second evaluation value being related to a body part included in the body part of the patient and serving as a candidate for said body part of interest, said second learned model being stored for each of a plurality of body parts of the patient,
- the processing of identifying said body part based on data for the B-mode image in said first region comprises processing of:
- inputting the data for said B-mode image in said first region to an input layer of said first learned model;
- obtaining, as an output of an output layer of said first learned model, said first evaluation value for the B-mode image of said data input to said input layer;
- and identifying said body part based on said first evaluation value, and
- the processing of identifying said body part of interest based on the data for said first color Doppler image in said second region comprises processing of:
- inputting the data for said first color Doppler image to an input layer of said second learned model that is regarding said body part identified based on the B-mode image in said first region;
- obtaining, as an output of an output layer of said second learned model, said second evaluation value for the first color Doppler image of said data input to said input layer;
- and identifying said body part of interest based on said second evaluation value.
