Patent ID: 7825393

Claim:
A computed radiography system, comprising: an imaging plate configured to either store a radiation energy pattern of an object or emit a plurality of prompt emission photons of the radiation energy pattern upon irradiation or a combination thereof; at least one light source configured to illuminate at least a sub-area of the imaging plate for a time period of less than about a second, the at least one light source configured to stimulate at least one of an emission of a plurality of photons of the radiation energy pattern stored in the imaging plate; a two dimensional imager configured to capture at least one two dimensional image from the at least a sub-area of the imaging plate using at least one of an image emitted from the radiation energy pattern stored or an image emitted from prompt emission or an image from an erased imaging plate or a combination thereof; and a filter wheel positioned between the light source and the imaging plate, the filter wheel comprising: a first filter configured to selectively pass illumination from the light source to the imaging plate to illuminate said plate to emit light of a shorter wavelength that is collected by the two dimensional imager during read out; a second filter configured to enable calibration of the imaging plate and an optical path via an excitation source that releases a stored energy pattern; and a third filter configured to erase the imaging plate.
