Abstract: A medical image processing apparatus according to one embodiment includes processing circuitry. The processing circuitry obtains input medical image data having a larger image region than output medical image data as a result of image processing; determines, in the input medical image data, a region that is smaller than the image region of the input medical image data and that is to affect image quality of the output medical image data when the image processing is applied to the input medical image data; performs the image processing to the determined region in the input medical image data; and outputs the output medical image data resulting from the image processing performed.

Abstract: A medical image processing apparatus according to one embodiment includes processing circuitry. The processing circuitry obtains input medical image data having a larger image region than that of output medical image data resulting from image processing; generates first intermediate image data by extracting from the input medical image data an image region including a region in the output medical image data and being smaller than the input medical image data; performs first image processing to the first intermediate image data, generates second intermediate image data based on the first intermediate image data having undergone the first image processing and on image data, of the input medical image data, containing an outside of an image region corresponding to the first intermediate image data; and converts the second intermediate image data to k-space data, and converts the k-space data having undergone k-spatial processing to the output medical image data.
