Patent ID: 7582878

Claim:
A photon counting radiation detection system comprising: at least one radiation detector including an array of anodes to generate a plurality of electrical signals in response to absorbing photons of ionizing radiation; an array of electrical signal detectors to read said plurality of electrical signals, wherein at least one of said electrical signal detectors includes: two or more electrical signal readers, wherein each of said signal readers is individually switchable between a coupled state in which an input of the signal reader is coupled to said electrode, and a decoupled state in which said input is decoupled from said electrode; and a controller to detect said plurality of electrical signals, to selectively switch said two or more signal readers to said coupled state to receive at least one sequence of two or more of the detected electrical signals, respectively, and to selectively activate said two or more signal readers to process the two or more detected electrical signals, respectively; and a readout system to generate an output corresponding to said radiation based on an output of said array of electrical signal detectors.
