Abstract:
A radiation detection system, comprising:an imaging module configured to receive radiation from an object;a sensing array disposed to receive said radiation from said imaging module and configured to have an array of sensing pixels which are responsive to said radiation to produce a plurality of pixel signals indicative of said radiation;a plurality of multiplexer circuits connected in parallel to said sensing array to simultaneously receive all of said pixel signals and configured to receive and hold said pixel signals according to a clock signal, wherein each of said multiplexer circuits has input ports to simultaneously receive a group of said pixel signals corresponding to a group of said pixels and sequentially outputs said group of said pixel signals at an output port; anda plurality of digitizers respectively connected to output ports of said multiplexer circuits and configured to respectively and simultaneously sample and digitize said pixel signals in parallel from said multiplexer circuits to produce a digital representation of said pixel signals from said sensing array, wherein each digitizer sequentially digitizes each pixel signal of said group of said pixel signals sampled and held by a respective multiplexer within one period of said clock signal before said respective multiplexer resets and receives group of pixel signals from said sensing array.
