ABSTRACT:
A computed radiography (CR) system for imaging an object is provided. The system includes a radiation source, a storage phosphor screen, an illumination source and a two dimensional imager. The radiation source is configured to irradiate the storage phosphor screen, and the storage phosphor screen is configured to store the radiation energy. The illumination source is configured to illuminate at least a sub-area of the storage phosphor screen to stimulate emission of photons from the storage phosphor screen. The two dimensional (2D) imager is configured to capture a two dimensional image from the storage phosphor screen using the stimulated emission photons. A method of reading a storage phosphor screen is also provided. The method includes illuminating at least a sub-area of the storage phosphor screen using an illumination source to stimulate emission of photons from the storage phosphor screen. The method further includes capturing at least one 2D image using a 2D imager, from at least a sub-array of the storage phosphor screen using the stimulated photons.
