a memory to store a program; and
processing circuitry configured, by executing the program, to perform alignment between a live image of a plurality of live images and a reference image of a plurality of reference images,
wherein the plurality of live images include a live fundamental image and a live harmonic image,
when the alignment is performed, the live image is set to the live fundamental image and then the alignment is performed between the live fundamental image and the reference image, and
after the alignment is completed, the live image is switched from the live fundamental image to the live harmonic image.
2. The ultrasonic diagnostic apparatus according to claim 1 , wherein the plurality of reference images include a reference fundamental image and a reference harmonic image,
when the alignment is performed, the reference image is set to the reference fundamental image, and
after the alignment is completed, the reference image is switched from the reference fundamental image to the reference harmonic image.
3. The ultrasonic diagnostic apparatus according to claim 1 , further comprising an image generation circuit configured to generate an image from a received signal,
wherein the image generation circuit is configured to generate the live fundamental image and the live harmonic image as the plurality of live images, when a contrast imaging is performed.
4. The ultrasonic diagnostic apparatus according to claim 3 ,
wherein the image generation circuit is further configured to generate the live fundamental image and the live harmonic image alternately frame by frame, when the contrast imaging is performed.
5. The ultrasonic diagnostic apparatus according to claim 3 ,
wherein the image generation circuit is further configured to
store a fundamental component and a harmonic component of the received signal when the contrast imaging is performed,
generate the live fundamental image based on the stored fundamental component, and
generate the live harmonic image based on the stored harmonic component.
6. The ultrasonic diagnostic apparatus according to claim 2 , further comprising a display configured to display the reference image,
wherein the processing circuitry is further configured to cause the display to display the reference fundamental image of the plurality of reference images or the reference harmonic image of the plurality of reference images based on volume data of the plurality of reference images.
7. A medical image processing apparatus, comprising:
a memory to store a program; and
processing circuitry configured, by executing the program, to perform alignment between a first image of a plurality of first images and a second image of a plurality of second images,
wherein the plurality of first images include a first fundamental image and a first harmonic image,
when the alignment is performed, the first image is set to the first fundamental image and then the alignment is performed between the first fundamental image and the second image, and
after the alignment is completed, the first image is switched from the first fundamental image to the first harmonic image.
