Abstract
A multi-functional and multi-modality radiation detector (10) is provided. The radiation detector (10) comprises at least two detector units (12a, 12b) having photosensitive pixels (14) and at least one scintillation device (20) optically coupled to the photosensitive pixels (14). The detector units (12a, 12b) are arranged next to each other on a substrate foil (24). Therein, the scintillation devices (20) of the detector units (12a, 12b) are spaced apart from each other, such that the radiation detector (10) is bendable. This allows the radiation detector (10) to be used in many different geometrical configurations.
Claims17
A radiation detector, comprising:
- a plurality of detectors, each detector comprising a plurality of photosensitive pixels and at least one scintillation device optically coupled to the plurality of photosensitive pixels;
- a substrate foil for carrying the detectors;
- and
- a switch arranged between two detectors of the plurality of detectors,
- wherein the detectors are arranged in juxtaposition on the substrate foil;
- wherein at least two directly adjoining scintillation devices of at least two directly adjoining detectors are spaced apart from each other, such that the radiation detector is bendable along at least a part of a bending region of the substrate foil,
- wherein the bending region is arranged between the at least two directly adjoining scintillation devices;
- wherein each detector comprises at least one of a separate addressing circuit for addressing the respective detector and a separate signal read-out circuit for reading-out signals from the respective detector;
- and
- wherein the switch is configured to electrically interconnect and decouple the two detectors.
A method for producing a radiation detector, the method comprising:
- providing a substrate foil and a plurality of detectors, each detector comprising a plurality of photosensitive pixels and at least one scintillation device optically coupled to the plurality of photosensitive pixels;
- arranging the plurality of detectors on the substrate foil in juxtaposition with respect to each other, such that at least two directly adjoining scintillation devices of at least two directly adjoining detectors are spaced apart from each other by a gap, and such that the radiation detector is bendable along at least a part of the gap;
- and
- arranging a switch between two detectors of the plurality of detectors,
- wherein each detector comprises at least one of a separate addressing circuit for addressing the respective detector and a separate signal read-out circuit for reading-out signals from the respective detector;
- and
- the switch is configured to electrically interconnect and decouple the two detectors.
