SCINTILLATOR ARRAY WITH HIGH DETECTIVE QUANTUM EFFICIENCY

The invention relates to a scintillator array for a radiation imaging detector. A method for manufacturing the scintillator array, a radiation imaging detector, and a medical imaging system are also provided. The scintillator array has a radiation receiving face and an opposing scintillation light output face. The scintillator array includes a plurality of scintillator elements and a separator material that is disposed between the scintillator elements. The separator material consists of separator particles that have a predetermined size and with this the separator material provides an optical separation of the scintillator elements by providing a physical spacing between the scintillator elements, the width of which spacing is defined by the separator particle size.
