SYSTEMS AND METHODS FOR NUCLEAR MEDICINE IMAGING USING SODIUM BASED CRYSTALS

Abstract:

An imaging detector is provided that includes a continuous NaI crystal, a glass plate, an array of SiPMs, and an array of concentrators. The continuous NaI crystal defines a reception side and a detection side. The glass plate is disposed on the detection side of the continuous NaI crystal, and is interposed between the detection side of the continuous NaI crystal and the array. The array of concentrators corresponds to the array of SiPMs, and is interposed between the array of SiPMs and the glass plate. Each concentrator has a reception side opening that is larger than a detection side opening, with the detection side opening disposed proximate to a corresponding SiPM.
