Abstract
Methods and systems for performing a patient scan using a three-dimensional (3D) cylindrical Positron Emission Tomography (PET) imaging system are provided. The method includes acquiring a count-rate profile of a brain, repositioning at least one of a detector and the brain based on the count-rate profile and a detector sensitivity profile, and scanning the brain when the acquired count-rate profile substantially matches the detector sensitivity profile.
Claims20
A method of performing a patient scan using a three-dimensional (3D) cylindrical Positron Emission Tomography (PET) imaging system including a detector, said method comprising:
- acquiring a count-rate profile of a brain;
- repositioning at least one of a detector and the brain based on the count-rate profile and a detector sensitivity profile;
- and
- scanning the brain when the acquired count-rate profile substantially matches the detector sensitivity profile.
A three-dimensional (3D) Positron Emission Tomography (PET) imaging system comprising a ring detector and a detector alignment module coupled to the ring detector, wherein the detector alignment module is programmed to:
- receive a count-rate profile of a brain;
- reposition a ring detector based on the count-rate profile and a detector sensitivity profile;
- and
- scan the brain when the acquired count-rate profile substantially matches the detector sensitivity profile.
A non-transitory computer readable medium encoded with a program to instruct a computer to:
- receive a count-rate profile of a brain;
- reposition a ring detector based on the count-rate profile and a detector sensitivity profile;
- and
- scan the brain when the acquired count-rate profile substantially matches the detector sensitivity profile.
