Patent Images
1. A radiation detector for detecting incident radiation, the detector comprising:
- at least a first detector element, wherein the first detector element comprises a set of scintillating optical guides arranged in an array for detecting a transversal radiation beam profile;
such that radiation incident on an optical guide generates scintillating light signals within the optical guide; and
wherein the set of scintillating optical guides are provided in a glass-based material doped with a rare earth dopant.

Abstract
The invention relates to a radiation detector suitable for use in connection with particle therapy applications. The detector comprises at least one set of scintillating optical guides which upon exposure to incident radiation generate scintillating light. The optical guides are arranged in an array, such as in a so-called harp configuration, for detecting a transversal radiation beam profile. The scintillating optical guides are provided in a glass-based material doped with a rare earth dopant. Of particular interest are the rare earth materials: Ytterbium, Holmium, Thulium and Erbium.
