Abstract
A system and method for imaging gamma- and x-ray, and charged particles sources employing a three dimensional array of scintillation elements arranged surrounding an emission source. According to a preferred embodiment, each element of the array comprises a scintillator element, a solid-state photon detector, and processing electronics to output an electronic signal. The elements may be efficiently packed in both the X-Y plane and stacked in the Z-axis, to provide depth of interaction information. The elements of the array are preferably hierarchically arranged with control electronics provided together for subarray modules (e.g., an n×m×1 module), and synchronization electronics provided at a larger scale. The modules preferably communicate with a control system through a shared addressable packet switched digital communication network with a control and imaging system, and receive control information from that system through the network.
