Nuclear medical diagnostic equipment and data acquisition method for nuclear medical diagnosis
First Claim
1. A nuclear medical diagnostic equipment wherein radiation which is emitted by a nuclide administered into a body of a patient is detected as projection data by a 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 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 said radiation detector 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 the image from the radiation detection data stored in said data storage unit on the basis of the result of the identification by said respiration identification unit.

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.

14. A nuclear medical diagnostic equipment wherein radiation which is emitted by a nuclide administered into a body of a patient is detected as projection data by a 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 round the patient; and
an image generation unit which generates the image by using the radiation detection data acquired by said radiation detector in a breathing state of the patient and anon-breathing state thereof based on breath holding, respectively. - View Dependent Claims (15, 16, 17)

18. A data acquisition method for a nuclear medical diagnosis wherein radiation which is emitted by a nuclide administered into a body of a patient is detected as projection data by a radiation detector, comprising the steps of:
-
obtaining identification information which identifies a breathing state of the patient and a non-breathing state thereof based on breath holding; and
storing the projection data in a manner to be capable of identifying whether the projection data have been acquired in the non-breathing state or in the breathing state, by using the identification information.

19. A data acquisition method for a nuclear medical diagnosis wherein radiation which is emitted by a nuclide administered into a body of a patient is detected as projection data by a radiation detector, comprising the steps of:
-
storing the projection data which have been acquired by the radiation detector in a breathing state of the patient and a non-breathing state thereof based on breath holding, respectively, in a manner to be capable of identifying whether the projection data have been acquired in the non-breathing state or in the breathing state; and
generating an image by using both the projection data acquired in the non-breathing state and the projection data acquired in the breathing state.
