Abstract:
1. A nuclear medical diagnostic equipment including a radiation detector, wherein radiation which is emitted by a nuclide administered into a body of a patient is detected as projection data by the radiation detector, and an image which indicates a distribution of the nuclide within the body of the patient is obtained on the basis of the projection data, comprising: a rotation unit which rotates the radiation detector around 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 is acquired by said radiation detector, with iterating an instruction of the breathing and an instruction of the non-breathing by breath holding alternately to the patient are stored in an identifiable manner on the basis of a result of the identification by said respiration identification unit; and an image generation unit which generates a first image by using only radiation detection data acquired in a state of non-breathing among the radiation detection data stored in said data storage unit on the basis of the result of the identification by said respiration identification unit and a second image by using radiation detection data acquired in the state of non-breathing and a state of breathing, wherein said radiation detector is configured to acquire data at both breathing periods and at non-breathing periods, the breathing and the non-breathing periods are associated to alternating radiographic directions, that are arranged at regular sectional intervals circularly around the patient, and the rotation unit is configured to stop the rotation of the radiation detector during the acquisition of data at the respective alternating radiographic directions.
