20100034350 | METHOD AND APPARATUS FOR SHORTENING FOOTPRINT OF MULTI-MODALITY IMAGING SYSTEM - A multi-modality imaging system includes a first imaging system and a second imaging system that is different from the first imaging system. The first and second imaging systems are slidingly mounted on at least one rail. A table has a movable pallet configured to extend through a scan range of the first imaging system while the first and second imaging systems are positioned proximate each other at one position along the at least one rail. The pallet is further configured to extend through a scan range of the second imaging system while the first and second imaging systems are positioned proximate each other at a different position along the at least one rail. At least a portion of the scan ranges overlap each other. | 02-11-2010 |
20100036232 | NUCLEAR MEDICINE IMAGING SYSTEM HAVING ATTENUATION CORRECTION - A nuclear medicine (NM) imaging system having attenuation correction (AC) has a stationary portion having an NM rotating portion mounted thereon. At least one gamma camera head is mounted on the NM rotating portion proximate a front side of the stationary portion and is configured to be rotated about a central axis. An AC portion comprises an X-ray source mounted on an AC rotating portion. The AC rotating portion is mounted proximate a back side of the stationary portion. The X-ray source is configured to be rotated about the central axis. | 02-11-2010 |
20100119043 | APPARATUS FOR PREVENTING DAMAGE TO RETRACTOR IN ROTATING IMAGING SYSTEM - A rotating imaging system has a rotating portion that is configured to rotate about a central axis. A tilt gauge has a housing mounted to the rotating portion and a gravity influenced flag with a free end configured to move separately with respect to the housing. The tilt gauge is configured to provide a visual indication of a rotational position of the rotating portion. | 05-13-2010 |
20100121604 | APPARATUS AND METHOD FOR IDENTIFYING THE ABSOLUTE ROTATION OF A ROTATING IMAGING SYSTEM - A rotating imaging system has a rotating portion, an idler, at least one sensor, a tilt sensor and a processor. The rotating portion has a diameter and rotates about a central axis. The idler rotates about an axis parallel to the central axis, and has a second diameter that is smaller than the diameter of the rotating portion. The rotating portion and the idler engage with each other such that both rotate simultaneously. The at least one sensor detects flags on the idler as the idler rotates. The tilt sensor is mounted to the rotating portion and determines a rotation angle of the rotating portion within a range of one revolution, and the processor determines an absolute rotation of the rotating portion based on at least a signal from the at least one sensor and the rotation angle determined by the tilt sensor. | 05-13-2010 |
