Medical information processing device, ultrasonic diagnosis device, and medical information processing method

A medical information processing device, comprising:

• a processing circuit configured to:
• acquire first ultrasonic data obtained based on a result of an ultrasonic scan of a subject;
• extract continuously a signal component representing an object from the first ultrasonic data;
• and
• output second ultrasonic data, based on the continuously extracted signal component representing the object, wherein the processing circuit is further configured to, for each of a plurality of attention positions included in the first ultrasonic data, extract a signal component at the attention position as the signal component representing the object, based on a result of comparing a signal value at a position in predetermined attention direction and range with respect to the attention position and a signal value at the attention position,
• wherein the processing circuit is further configured to, for each of the attention positions included in the first ultrasonic data, compare the signal value at the attention position and the signal value at the position in the predetermined range for each attention direction with respect to the attention position, and based on a result of the comparison and a weight coefficient determined in advance for each attention direction, weight the signal component at the attention position.

An ultrasonic diagnosis device, comprising:

• a transmitter/receiver circuit configured to cause an ultrasonic probe to perform an ultrasonic scan of a subject;
• and
• a processing circuit configured to:
• acquire addition data as first ultrasonic data by adding up a plurality of pieces of frame data that are continuous in a time direction and that are obtained based on a result of the ultrasonic scan of the subject, the addition data having a higher signal-noise (SN) ratio than each of the plurality of pieces of frame data;
• acquire a signal component representing a spatially continuous object by extracting a local peak position from the first ultrasonic data;
• and
• output second ultrasonic data, based on the acquired signal component representing the spatially continuous object.
