Abstract: An imaging system (10) comprises at least one radiation detector unit (16) disposed adjacent a field of view (20) to detect and measure radiation from the field of view (20). The detector unit (16) includes multiple detection modules (18) which each detects radiation from a prespecified region of the field of view (20), each region being a fraction of the field of view. One or more pinholes (52) are associated with the detector unit (16). Each pinhole (52) receives radiation from the prespecified region of the field of view (20) and transmits radiation to one or more associated detection modules (18).

Abstract: The invention relates to a detector element of an instrument for combined production of a CT x-ray image and a PET image. The detector element contains a conversion element (1), which produces a charge signal (Q) proportional to the energy of incident x-ray quanta (X) and gamma quanta (y). In an evaluation unit, the charge signal (Q) is converted by an amplifier (30) into a voltage pulse (U), which is subsequently processed separately by a single-pulse analyzer (50) for determining PET information (Y PET ) and a pulse-sequence analyzer for determining CT information (Y CT ). By using a common amplifier, the detector element achieves high accuracy even for conversion elements (1) with a weak charge signal.

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.

Abstract: A radiation detector comprises a plurality of detector units and x-ray absorption members placed between the respective detector units. An individual detector unit includes a sensor element and read-out circuitry. The x-ray absorption members have a wider portion and a narrower portion and the read-out circuitry is accommodated at the narrower portion of the x-ray absorption member. Hence, the read-out circuitry is shielded from incident x-rays by the wider portion.

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: A nuclear imaging system includes a scanner (8), such as a PET scanner. A patient is injected with a [ 13 N]ammonia radioisotope tracer which is contaminated with a small percent of 18 F contamination. The scanner receives radiation from the injected tracer and a reconstruction processor (28) reconstructs the detected radiation into image representations. A warning generator (12) generates warnings to the clinician concerning the effects of the 18 F contamination. A calibration processor (16) generates an estimated decay curve based on a time since the end of the proton bombardment which created the tracer and a priori information about the tracer. An activity meter (42) measures radiation emitted from a sample of the tracer and a dose calibrator (44) determines a decay curve from the measured radiation. Either the detected radiation is corrected in accordance with one of the decay curves during reconstruction or a correction processor (50) corrects reconstructed images in accordance with one or both of the decay curves. A display (14) displays uncorrected reconstructed images and the decay curve and/or the corrected images.
