Abstract
A nuclear medicine imaging system includes a bed having a 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 a direction of translation;
- a detector disposed rotationally about an axis of rotation substantially parallel to said direction of translation;
- and
- a single 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, such that transmission radiation detected by said detector as said detector and radioactive line source are rotated about said axis of rotation has a line source distribution profile.
A method of nuclear medicine imaging comprising:
- translating a bed along a direction of translation;
- rotating a detector about an axis of rotation substantially parallel to said direction of translation;
- disposing a single 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 single radioactive line source about said axis of rotation such that transmission radiation detected by said detector as said line source is rotated about said axis of rotation has a line source distribution profile.
A system for nuclear medicine imaging comprising:
- means for translating a bed along a direction of translation;
- means for rotating a detector about an axis of rotation substantially parallel to said direction of translation;
- means for disposing a single 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 such that transmission radiation detected by said detector as said line source is rotated about said axis of rotation has a line source distribution profile.
