Ultrasonic diagnostic apparatus and program

摘要

An ultrasonic diagnostic apparatus comprises an ultrasonic probe configured to transmit ultrasound to a test body and receive an echo signal, an image generation unit configured to generate a plurality of tomograms with respect to the test body based on the echo signal, an image memory configured to record the generated tomograms, and a control processor. The control processor performs control such that image processing of extracting a microstructure is performed, using correlation between a tomogram stored in the image memory and a tomogram corresponding to a position of the ultrasonic probe at that point in time. The microstructure-extracted image is displayed on the display part in a predetermined form.

1. An ultrasonic diagnostic apparatus configured to ultrasonically scan a test body and acquire a tomogram, the apparatus comprising:
an ultrasonic probe configured to transmit ultrasound to the test body and receive an echo signal from the test body; a position detector configured to detect a position of the ultrasonic probe at each of a plurality of timings; processing circuitry configured to generate a plurality of time series tomograms of the test body based on outputs from the ultrasonic probe, the time series tomograms corresponding to the plurality of timings, respectively; a memory configured to store the time series tomograms generated by the processing circuitry, wherein the processing circuitry is further configured to
determine a frame interval based on an amount of movement calculated from positions detected by the position detector and a frame rate at which the time series tomograms are generated,select, from among the time series tomograms stored by the memory, a reference tomogram at the frame interval from a target tomogram included in the time series tomograms, the reference tomogram being generated prior to the target tomogram, andgenerate a microstructure-extracted image based on the reference tomogram and the target tomogram; and a display configured to display the microstructure-extracted image generated by the processing circuitry in a predetermined form.
