Abstract
A CT scanner ( ) includes a reconstruction processor ( ) and a mosaic X-Radiation detector ( ). The mosaic detector includes plural detector elements ( ) arranged in abutting relationship and configured for the desired imaging application. The detector elements include scintillating crystals ( ) in optical communication with a back-illuminated photodiode array ( ) or modified top-surface photodiode array ( ) for converting emitted light into electrical charge. The photodiode array is mounted on a carrier substrate ( ) via bump ( ) bonding. The carrier substrate provides a conductive path routing the photodiode array output through to contacts on the back side for connection to readout electronics ( ). The carrier substrate and readout electronics are contained within the footprint defined by the photodiode array, allowing the detector elements to be abutted on any and all sides, thus permitting the mosaic detector to be tailored to any desired size and shape.
