Abstract
A nuclear scanner includes an annular support structure (32) which supports a plurality of detector modules (30). Each detector module includes a cooling and mounting structure (34) to which a plurality of tiles (40) are mounted by passing pins (46-49) through holes (38) in the cooling and mounting structure (34) to position each tile and thermally connect each tile to the cooling and mounting structure (34). A tile mount (44) on the side of the tile that makes contact with the cooling and mounting structure has a smooth face to make contact with the cooling and mounting structure to provide good thermal contact between the tile (40) and the cooling and support structure (34).
Claims20
A tile comprising:
- an array of radiation detectors which generate signals in response to receiving radiation events and associated electronics;
- a mount which mounts the tile to and in the thermal communication with a cooling and mounting structure and which positions a mounting face of the tile relative to the cooling and mounting structure.
A generally annular PET detection system comprising:
- a plurality of annular support rings;
- a plurality of modules mounted to the annular support rings, each module including a cooling and support plate assembly having a plurality of holes through the cooling and support plate;
- and
- a plurality of tiles, each tile comprising a detector, mounted to and supported by the cooling and support plate assembly of the respective module by pins received in the holes such that a tile without any exposed sides can be removed from the module without removing adjacent tiles by pushing the pins of the tile to be removed out of the respective holes of the module.
A generally annular PET detection system comprising:
- a pair of annular support rings;
- a first annular shield ring disposed adjacent a first of the annular support rings;
- a plurality of modules mounted to and supported by the annular support rings, each module including a cooling and support plate assembly which defines electrical connector apertures;
- a plurality of tiles, each tile comprising a detector and an electrical connector on or recessed in a face of the tile such that the electrical connector aperture receives the electrical connector, each tile mounted to and supported by the cooling and support plate assembly of the respective module, the cooling and support plate assembly defining more electrical connector apertures than the number of mounted tiles such that different numbers of tiles can be mounted to the respective module in a group with a first side of the group adjacent the first annular shield ring;
- and
- a moveable annular shield ring mounted between a second of the annular support rings and the plurality of tiles such that the movable annular shield ring is positioned adjacent a second side of the group of tiles such that the movable annular shield ring can be disposed to accommodate different numbers of tiles.
