Nuclear medical diagnostic equipment and data acquisition method for nuclear medical diagnosis

Abstract

A nuclear medical diagnostic equipment wherein radiation which is emitted by a nuclide administered into the body of a patient is detected as projection data by a gamma camera, and an image which indicates the distribution of the nuclide within the body of the patient is obtained on the basis of the projection data. The equipment comprises a rotation unit which rotates the radiation detector round the patient, a respiration identification unit which identifies breathing of the patient and non-breathing thereof based on breath holding, a data storage unit in which the radiation detection data acquired by the radiation detector are stored in an identifiable manner on the basis of a result of the identification by the respiration identification unit, and an image generation unit which generates the image from the radiation detection data stored in the data storage unit on the basis of the result of the identification by the respiration identification unit.
