Abstract
A system, a method, and computer readable media for generating a corrected image from image information extracted from an X-ray sensitive plate. First, flaw map image information is extracted from an X-ray sensitive plate in order to determine any flaws (e.g., scratches) on the plate. Then the plate is exposed to capture physical image information (e.g., anatomical information) and the physical image information is extracted from the plate. The flaw map information is used to identify corresponding flaws in the extracted physical image information. Image processing is performed to correct the flaws (e.g., due to scratches on the X-ray sensitive plate) in the physical image information to form a corrected physical image.
Claims31
A method to generate a corrected image from image information extracted from an X-ray sensitive plate, said method comprising:
- generating flaw map image data using an X-ray sensitive phosphor plate;
- generating physical image data using said X-ray sensitive phosphor plate;
- identifying scratched pixel locations within said flaw map image data using a computer-based platform;
- correlating pixel locations within said physical image data with said identified scratched pixel locations within said flaw map image data using said computer-based platform;
- and
- correcting said correlated pixel locations within said physical image data using said computer-based platform to generate a corrected physical image.
A system to generate a corrected image from image information extracted from an X-ray sensitive plate, said system comprising:
- means for generating flaw map image data using an X-ray sensitive phosphor plate;
- means for generating physical image data using said X-ray sensitive phosphor plate;
- means for identifying scratched pixel locations within said flaw map image data;
- means for correlating pixel locations within said physical image data with said identified scratched pixel locations within said flaw map image data;
- and
- means for correcting said correlated pixel locations within said physical image data to generate a corrected physical image.
Non-transitory computer readable media having computer readable instructions recorded thereon for generating a corrected image from image information extracted from an X-ray sensitive plate, said instructions comprising:
- instructions for identifying scratched pixel locations within flaw map image data extracted from an X-ray sensitive phosphor plate;
- instructions for correlating pixel locations within physical image data extracted from said X-ray sensitive phosphor plate with said identified scratched pixel locations within said flaw map image data;
- and
- instructions for correcting said correlated pixel locations within said physical image data to generate a corrected physical image.
