Abstract: A positron emission tomography imaging system (100) includes a plurality of detector elements (1301..i) and a plurality of compute elements (1401..j). Each compute element (1401..j) comprises one or more of the detector elements (1301..i), and the compute elements (1401..j) are arranged around the bore (110) of the PET imaging system. Each compute element (1401..j) includes a first communication path (1601..j) coupling the compute element to an adjacent compute element in a5circumferential direction around the bore, and a second communication path (1701..e) coupling the compute element to a non-adjacent compute element in the circumferential direction. Each computeelement (1401..j) includes a processor configured to receive the event data generated by its one or more detector elements (1301..i), and to communicate the event data to the processor of its adjacent computeelement, and to the processor of its non-adjacent compute element, via its first communication path10(1601..j), and via its second communication path (1701..j), respectively.

Abstract: A positron emission tomography imaging system (100) includes a plurality of gamma detector elements (130i), a plurality of detector cassettes (140j), and mounting frame (150). Each detector cassette (140j) is configured to replaceably receive a plurality of gamma detector elements (130i). The mounting frame (150) is configured to replaceably receive the detector cassettes (140j) at a plurality of angular positions (fk) around the axis (120) of the bore (110) such that at each angular position (fk) a plurality of detector cassettes (140j) are receivable along a direction parallel to the axis (120) of the bore (110), and a plurality of gamma detector elements (130j) are receivable within a cassette (140j) in a transaxial direction with respect to the axis (120) of the bore (110).

Abstract: The present invention relates to a photon detector, a detector device and an imaging apparatus for detection of radiation, in particular gamma radiation. The photon detector comprises a direct conversion detector (11) configured to detect gamma radiation and generate direct conversion signals responsive to impingement of photons, a single photon avalanche diode. SPAD, detector array (12) comprising a plurality of SPAD detectors (13) configured to detect Cherenkov radiation generated in the direct conversion detector in response to impingement of photons and generate SPAD detection signals, and an electrode array (14) comprising aurality of electrodes arranged on top of the direct conversion detector and between the direct conversion detector and the SPAD detector array and configured to read out the direct conversion signals. The SPAD detector array substantially covers a surface on one side of the direct conversion detector.
