RADIATION DETECTOR WITH PHOTOSENSITIVE ELEMENTS THAT CAN HAVE HIGH ASPECT RATIOS

摘要

The invention relates to a radiation detector (100) and to a method for manufacturing such a detector. In a preferred embodiment, the radiation detector (100) comprises an array of photosensitive pillars (110) that are embedded in a conversion material (120). The photosensitive pillars may particularly be diodes connected at their ends to external circuits (130, 140). The conversion material (120) may particularly comprise a powder of scintillator particles (121) embedded in a matrix of binder.

主权项

1. A radiation detector for detecting primary photons of an incident radiation, comprising:
a conversion material for converting primary photons of incident radiation into secondary photons; at least two photosensitive pillars that extend in a first direction through said conversion material for converting said secondary photons into electrical signals, wherein at least two of the at least two photosensitive pillars have different heights and/or different positions on an axis parallel to the first direction.
