Abstract:
An apparatus for evaluating image processing performed on a plurality of original radiographic images each stored on a different photostimulable phosphor screen, comprising:means for scanning each screen with stimulating radiation; means for detecting the light emitted from each screen upon stimulation; means for converting the detected light emitted from each screen into a digital signal representation of the original radiographic image stored on the screen; means for determining a set of processing parameters for each original radiographic image; means for processing the digital signal representation of each original radiographic image on the basis of the set of processing parameters determined for the image; means for deducing from the digital signal representation of each original radiographic image a reduced version representing a reduced number of pixels; means for storing an evaluation data record for each of the plurality of original radiographic images, the evaluation data record for each image comprising data identifying the image, the set of processing parameters for the image, intermediate processing results for the image, and the reduced version of the image; means for identifying one of the plurality of original radiographic images to be evaluated; means for retrieving the evaluation data record pertaining to the identified image; and means for generating an output of the contents of the retrieved evaluation data record.
