Title:

PHOTOELECTRIC CONVERTER, DETECTOR, AND SCANNING APPARATUS

Document Type and Number:

WIPO Patent Application WO/2016/074560

Kind Code:

A1

Abstract:

A photoelectric converter comprises a silicon photomultiplier array (5) and a light guide (4) coupled with the silicon photomultiplier array (5). The silicon photomultiplier array (5) is obtained by splicing i×j silicon photomultipliers on a horizontal plane, i and j being both integers greater than or equal to 2. A detector comprises a scintillation crystal (1), an electronics system (3), the light guide (4), and silicon photomultipliers. A scanning apparatus comprises a detecting device and a rack. The detecting device comprises the detector, and the detector comprises the photoelectric converter. The silicon photomultipliers have small sizes and are arranged closely. With an appropriate quantity of silicon photomultipliers of appropriate sizes in combination with a light guide having a suitable shape, a high spatial resolution PET detector can be built, so that spatial resolution of an entire PET system is improved, and it is suitable for building a PET detector having DOI and TOF performance, which can be used for PET/MRI, and the costs are low.
