Abstract: A nuclear medicine imaging system that includes a plurality of detectors arranged about an imaging region. A transmission source can be provided opposite the detectors and rotating about the imaging region to obtain different imaging angles. The nuclear imaging system provides for the ability to acquire high sensitivity transmission data with high emission data spatial resolution.

Abstract: The invention relates to a detector element (1) for gamma radiation, which is particularly suitable for use in a PET apparatus. The detector element (1) consists of two or more different conversion units (11, 12), which react to the absorption of a gamma quantum (y) with light emissions (λ 1 , λ 2 ) of different spectral composition. A photodetector arrangement (30) may therefore discriminate between the sites of origin of the light emissions by means of their spectral characteristics.

Abstract: An x-ray detector comprises a conversion layer for converting x-radiation into optical radiation. Photosensitive elements notably photodiodes to derive electronic signals from the optical radiation received by the photosensitive elements. The conversion layer contains Caesium-iodide doped with Thallium (CsI:Tl); the Caesium-iodide doped with Thallium is ultrapure and the Tl-doping level is in the range of 0.25-1.00 at%.
