Medical image diagnosis apparatus and image reconstruction method |
摘要 |
In a nuclear medicine imaging apparatus as a medical image diagnosis apparatus according to one embodiment, a PET detector is configured to detect a gamma ray emitted from a nuclide introduced into a body of a subject. A PET image reconstruction unit is configured to reconstruct a nuclear medicine image (PET image) as a medical image from the gamma ray projection data created based on the gamma ray detected by the PET detector using successive approximation. A controller is configured to control the PET image reconstruction unit to change the parameter used in the successive approximation depending on information regarding the scanning region in the body of the subject.
