1. A medical image processing apparatus, comprising:
processing circuitry configured to:
obtain Time-of-Flight (TOF) depiction image data generated on a basis of an annihilation point of a gamma ray, the TOF depiction image data representing a TOF depiction image in which annihilation point indicating a position of occurrence of annihilation event is depicted as a point or a line; and
output reconstructed Positron Emission computed Tomography (PET) image data on a basis of the TOF depiction image data and a trained model that outputs the reconstructed PET image data on a basis of an input of the TOF depiction image data,
wherein the processing circuitry outputs the reconstructed PET image data, on a basis of the trained model corresponding to a type of drug administered for a subject in a scan at a time of acquiring coincidence counting information from which the obtained TOF depiction image data is derived, the trained model being one of a plurality of trained models corresponding to a plurality of types of drugs.
