Abstract
A multi-layered mega-voltage digital imager is disclosed. In one embodiment, the radiation to particle conversion and particle to electricity conversion is paired as a modular entity. The entity is replicated on top of each other as a layered unit to build an imager with increased resolution and efficiency. Due to this paired replication, sub-images from each replicated pair may be selectively combined and processed to enhance the quality of the image. By varying and adding components at each layer, a different dose rate, and increased resolution, energy sensitivity and efficiency are achieved. The multilayered approach is cost effective and removes problems associated with traditional high efficient MV imagers used for high energy radiations.
