An ultrasound diagnostic apparatus includes processing circuitry. The processing circuitry generates a first image based on an echo signal obtained by transmission and reception of ultrasound waves. The processing circuitry acquires a second image that is an image generated by a medical image diagnostic apparatus. The processing circuitry performs a registration of the first image and the second image, by discretely setting a plurality of relative positions of the first image and the second image within a specified range, calculating the similarity between the first image and the second image corresponding to the plurality of relative positions respectively, updating the plurality of the relative positions based on the calculation result of the similarity, and recalculating the similarity corresponding to the plurality of the updated relative positions respectively. The processing circuitry causes a display to display the images obtained after the registration.

Ultrasound diagnostic apparatus, image processing apparatus, and image processing method

A medical image diagnostic apparatus according to an embodiment includes processing circuitry. The medical image diagnostic apparatus performs image registration between medical image data. The processing circuitry extracts a structure of the subject included in the medical image data. The processing circuitry sets a display scale of the subject to a specified value. The processing circuitry performs image registration between the medical image data on the display scale of the specified value.

Medical image diagnostic apparatus, medical image diagnostic method, and ultrasonic diagnostic apparatus

An analysis apparatus according to an embodiment includes processing circuitry. The processing circuitry performs registration between first ultrasound image data obtained at a first phase by an ultrasound diagnostic apparatus and first medical image data obtained by a medical image diagnostic apparatus other than the ultrasound diagnostic apparatus and performs registration between the first ultrasound image data and second ultrasound image data obtained at a second phase different from the first phase by the ultrasound diagnostic apparatus, to generate second medical image data registered with the second ultrasound image data; and combines the second ultrasound image data and the second medical image data to generate a single image, thereby performing registration between ultrasound image data by the ultrasound diagnostic apparatus and medical image data by the medical image diagnostic apparatus.

Analysis apparatus, ultrasound diagnostic apparatus, and analysis method

A medical image diagnostic apparatus according to an embodiment includes processing circuitry configured to determine a plurality of small blocks for each of a plurality of pieces of medical image data, generate a plurality of superpixels corresponding to the plurality of small blocks, assign a label to at least one of the plurality of pieces of medical image data, and perform registration between the plurality of pieces of medical image data using the plurality of superpixels and the label.
