Abstract: A medical image processing apparatus includes processing circuitry. The processing circuitry acquires first feature data related to the structure of interest from first medical image data scanned at a first timing and second feature data related to the structure of interest from second medical image data scanned at a second timing, estimates the third feature data by estimating the structure of interest at the second timing by simulation based on the first feature data, and calculates a first feature value and a second feature value that is a local feature value more than the first feature value from the second feature data and the third feature data. The processing circuitry specifies a plurality of parameter sets based on optimization calculation having a loss function including the first feature value, and determines a parameter set of interest from the plurality of parameter sets based on the second feature value.
