1. A medical information processing apparatus, comprising:
processing circuitry configured to
acquire first data generated as a result of a reception by a radio frequency coil and acquire information about reception characteristics of the radio frequency coil that contribute to a signal-to-noise ratio of the first data;
perform a denoise process on the first data to obtain second data from the first data, the second data being the denoised first data;
determine multiple mixing rates based on the reception characteristics of the radio frequency coil, each mixing rate being a rate of a mixture of a first medical image according to the first data and a second medical image according to the second data; and
generate a mixed image by mixing the first medical image and the second medical image according to the determined multiple mixing rates,
wherein the processing circuitry is further configured to generate the mixed image by mixing the first medical image and the second medical image according to the mixing rates based on the information about reception characteristics of the radio frequency coil.
