摘要： An apparatus for use with a detector system including a solid state flat panel detector and an image processor, the detector including a plurality of pixels, each pixel generating an initial intensity signal, the initial signals together defining an initial image, the processor storing an initial bad pixel map that includes a known bad pixel set, after signals are generated, the processor automatically using intensity signals corresponding to other than the bad pixel set to generate replacement intensity signals for each of the bad pixel set pixels thereby generating a corrected image, the apparatus for identifying additional bad pixels, the apparatus comprising a processor that, after the image data is collected, examines at least one of the initial image and the corrected image to identify a likely additional bad pixel set including pixels that have unexpected values and an interface for indicating the likely bad set to a system user.

摘要： A method and apparatus for displaying an image generated by at least one detector of an imaging unit are disclosed herein. The method includes creating a pixel map identifying locations of bad pixels in an array of pixels in the image detected by the at least one detector, linking the pixel map to the image, and providing for selective display of the pixel map. Bad pixels behave from a group including pixels which do not respond electrically and pixels which are statistically different from surrounding pixels in the array of pixels. The apparatus includes an imaging unit for generating x-rays which pass through a body of interest, at least one detector unit for detecting the x-rays, and a processing unit for identifying bad pixels within the detected image.
