Medical image processing apparatus and medical image diagnostic apparatus

A medical image processing apparatus which analyzes blood flow dynamics in a predetermined region of a subject, the blood flow dynamics being generated from medical images obtained by imaging the predetermined region in time sequence over a plurality of time phases, the medical image processing apparatus comprising:

• processing circuitry configured to
• correct pixel values of a target image after being aligned, according to an amount of deformation of the target image when the target image is aligned with a reference image by executing the program read out from memory circuitry, the reference image and the target image being among the medical images in the plurality of time phases,
• set a same grid on each of the reference image and the target image, thereby dividing each of the reference image and the target image into a plurality of regions in a grid-like arrangement,
• calculate a relational expression between the deformation rate of the grid and a rate of change of the pixel values, and
• correct the medical image based on the relational expression.
