POSITRON EMISSION COMPUTED TOMOGRAPHY DEVICE, METHOD EXECUTED BY POSITRON EMISSION COMPUTED TOMOGRAPHY DEVICE, AND PROGRAM

摘要

A positron emission computed tomography apparatus according to an embodiment includes a minimum number deriving unit (170), an excess length deriving unit (170), and a starting point deriving unit (170). The minimum number deriving unit (170) derives a minimum number that is the number of scans in a case where multiple scans are successively performed and that is necessary to image at least an axial extent of a region of interest. The excess length deriving unit (170) derives an excess length that is excessively scanned by the scans in the axial direction based on the minimum number of scans, the axial extent of the region of interest, and the length of an axial FOV. The starting point deriving unit (170) derives a starting point of a first scan of the scans so that the excess length is equally allocated on each end of the region of interest in the axial direction.
