A medical image processing apparatus according to an embodiment for visualization of each of plural captured image volume data having time of day information includes a generator configured to generate interpolation volume data for interpolation in the plural captured image volume data, based on the plural captured image volume data, and a display unit configured to visualize and display the plural captured image volume data and the interpolation volume data. The generator extracts a feature region in the captured image volume data, and is configured such that processing for generating the interpolation volume data for the feature region is different from processing for generating the interpolation volume data for other regions, so as to suppress a change in shape of the feature region.
