SYSTEM AND METHOD FOR CORRECTION OF GEOMETRIC DISTORTION OF MULTI-CAMERA FLAT PANEL X-RAY DETECTORS |
摘要 |
System and method for correcting geometric distortion in a multi-camera flat panel X-Ray detector. A scintillator converts X-Ray radiation generated by an X-Ray source into detectable radiation. Internal markers are placed at known locations adjacent to the scintillator, inside a casing of the detector. External markers placed at known locations outside the casing, adjacent to a cover of the detector. At least one imaging sensor acquires, during the calibration phase, a partial image depicting the external markers and the internal markers. The location of the external markers and the internal markers on the partial X-Ray image is found. A parallax free transformation for correcting geometric distortion based on differences between relation between physical location of the external markers and location of the external markers on the X-Ray image and relation between physical location of the internal markers and location of internal markers on the partial X-Ray image is calculated. |
