Abstract
A nuclear medicine imaging system includes a bed having an direction of translation, a detector disposed rotationally about an axis of rotation substantially parallel to the direction of translation, and a radioactive line source disposed rotationally about the bed substantially opposite the detector at a first predetermined non-zero angle to the axis of rotation and a second predetermined non-zero angle to a plane of rotation of the detector. The bed may be translated along the along the direction of translation while the detector is rotated about the axis of rotation.
Claims18
A nuclear medicine imaging system comprising:
- a bed having an direction of translation;
- a detector disposed rotationally about an axis of rotation substantially parallel to said direction of translation;
- and
- a radioactive line source disposed rotationally about said bed substantially opposite said detector at a first predetermined non-zero angle to said axis of rotation and a second predetermined non-zero angle to a plane of rotation of said detector.
A method of nuclear medicine imaging comprising:
- translating a bed along an direction of translation;
- rotating a detector about an axis of rotation substantially parallel to said direction of translation;
- disposing a radioactive line source substantially opposite said detector at a first predetermined non-zero angle to said axis of rotation and a second predetermined non-zero angle to a plane of rotation of said detector;
- and
- rotating said radioactive line source about said axis of rotation.
A system for nuclear medicine imaging comprising:
- means for translating a bed along an direction of translation;
- means for rotating a detector about an axis of rotation substantially parallel to said direction of translation;
- means for disposing a radioactive line source substantially opposite said detector at a first predetermined non-zero angle to said axis of rotation and a second predetermined non-zero angle to a plane of rotation of said detector;
- and
- means for rotating said radioactive line source about said axis of rotation.
