Abstract
A nuclear imaging system and method are provided for synchronously recovering the field of view of a target to be imaged includes multiple detectors attached to a gantry, a support member or wobbling ring and a driver. The driver engages the wobbling ring whereby the wobbling ring rotates with respect to the gantry. The wobbling ring cooperates with the detectors causing the detectors to synchronously adjust to multiple viewing positions of a detection target, enabling recovery of the full field of view from an otherwise truncated field of view if the detectors were stationary with respect to the gantry.
Claims21
A nuclear image detection system for recovering a full field of view of a target to be imaged, comprising:
- a gantry;
- multiple detectors each having a gantry attachment site thereon and being attached to said gantry at said gantry attachment site;
- and
- an arrangement cooperating with said gantry such that the arrangement synchronously moves said multiple detectors to different viewing angles with respect to said gantry whereby the full field of view of a target to be imaged can be recovered.
A nuclear image detection system for detection of a full field of view of a target to be imaged, comprising:
- a plurality of detectors;
- a gantry;
- wherein the detectors are attached to the gantry in an arrangement such that the detectors can have multiple viewing angles of said target with respect to the gantry;
- and
- means for synchronously moving the detectors with respect to the gantry such that they can each be simultaneously moved to one of said multiple viewing angles whereby the full field of view can be recovered.
A method for recovery of a full field of view of a target to be imaged by a nuclear medicine imaging system, comprising the steps of:
- providing multiple detectors on a gantry such that said detectors will be positioned at a predetermined distance from said field of view, wherein the detectors are attached to the gantry in a manner that allows said detectors to be moved to multiple viewing angles;
- and
- synchronously moving said detectors to different viewing angles with respect to said gantry such that said detectors simultaneously view said target from corresponding predefined viewing angles with respect to said gantry to recover a full field of view of said target from an otherwise truncated field of view if said detectors were not positionable to multiple viewing angles with respect to said gantry.
A nuclear imaging system for recovering a full field of view of a target to be imaged, comprising:
- a gantry;
- a wobbling ring;
- a plurality of detectors each having a gantry pivot site at which a detector is attached to said gantry and a wobbling pivot site at which a detector is attached to said wobbling ring;
- and
- a driver that rotates said wobbling ring with respect to said gantry such that as said wobbling ring rotates said plurality of detectors are synchronously pivoted about their respective gantry pivot sites to a plurality of imaging viewing angles so as to recover the full field of view of said target.
