Patent ID: 8306184

Claim:
A clinical x-ray pixel array system comprising: (a) a pulsed MeV electron beam source including a linear accelerator operable to produce a pulsed electron beam; (b) an n-stage scanning system operable to scan the electron beam along a path, n being an integer of at least two; (c) a plurality of x-ray targets positioned to convert the electron beam to x-rays; (d) an x-ray pixel array collimator positioned downstream of the x-ray targets to collimate the x-rays from one of the x-ray targets for producing an x-ray pixel beam, wherein the collimator comprises a plurality of apertures, and wherein the n-stage scanning system is operable to selectively scan and aim the electron beam at predetermined apertures of the collimator; and (e) a controller operable to control the pulsation of the electron beam source and the n-stage scanning system for sequentially generating a predetermined spatial and temporal x-ray pixel beam array pattern.
