Abstract: When employing specular reflective material in a scintillator crystal array, light trapping in the crystal due to repetitive internal reflection is mitigated by roughening at least one side(16) of each of a plurality of pre-formed polished scintillator crystals. A specular reflector mate¬ rial (30) is applied (deposited, wrapped around, etc.) to the roughened crystals, which are arranged in an array. Each crystal array is coupled to a silicon photodetector (32) to form a detector array, which can be mounted in a detector for a functional scanner or the like.

Abstract: An apparatus (208) includes a plurality of photosensors (310). Photon trigger signals produced in response to signals from the sensors are received by a trigger line network that includes segment (302), intermediate (304), and master (306) lines. The trigger network is configured to reduce a temporal skew introduced by the trigger line network. Validation logic (324) provides a trigger validation output signal (610).

Abstract: A time of flight positron emission tomography apparatus (100) includes a detector (106), a data acquisition system (120), a coincidence system (122) and a reconstructor (129). Various elements of an imaging chain influence the temporal resolution of the system (100) so that positron data collected along different lines of response is characterized by different temporal resolutions. The different temporal resolutions are used to estimate the positions of detected events along their respective lines of response.

Abstract: When designing detector arrays for diagnostic imaging devices, such as PET or SPECT devices, a virtual detector, or pixel, combines scintillator crystals (10, 20, 40) with photodetectors (12) in ratios that deviate from the conventional 1 : 1 ratio. For instance, multiple photodetectors can be glued to a single crystal to create a virtual pixel (10, 20, 40) which can be software-based or hardware-based. Light energy and time stamp information for a gamma ray hit on the crystal can be calculated using a virtualizer processor or using a trigger line network and time-to-digital converter logic. Additionally or alternatively, multiple crystals (54) can be associated with each of a plurality of photodetectors (52). A gamma ray hit on a specific crystal is then determined by a table lookup of adjacent photodetectors (52) that register equal light intensities, and the crystal (54) common to such photodetectors (52) is identified as the location of the hit.

Abstract: The present invention relates to a pixellated detector with an enhanced structure to enable easy pixel identification even with high light output at crystal edges. A half-pixel shift between scintillator crystals (50) and detector pixels (12) enables the identification of a crystal (50) from four detector pixels (12) instead of nine pixels in case of optical crosstalk. Glass plates without any mechanical structuring may be used as a common substrate (60) for detectors and scintillators.
