Automatically defect pixels detecting method, for flat panel detector in e.g. digital mammography system, involves recognizing defect pixels depending on appropriate pixel value of mean value and middle deviation of all pixel values

摘要

#CMT# #/CMT# The method involves capturing multiple images (1) e.g. dark images, by a detector and generating a noise image the images. An average value of all pixel values of the noise image is determined. An average deviation of all pixel values of the noise image is determined from the average value. The pixel of the detector is recognized as defect pixels depending on an appropriate pixel value within the noise image, of the mean value of all the values and middle deviation of the pixel values. The pixel of the detector is arranged in middle of a predetermined section. #CMT# : #/CMT# Independent claims are also included for the following: (1) an imaging fluoroscopy system comprising a control unit (2) a computer program having a set of instructions for automatically detecting defect pixels in a detector (3) an electronic readable data carrier comprising a set of instructions for automatically detecting defect pixels in the detector. #CMT#USE : #/CMT# Method for automatically detecting defect pixels of a detector i.e. flat panel detector, in a fluoroscopic imaging system (claimed) e.g. X-ray medical imaging system such as stationary or mobile C-arms or digital mammography system. #CMT#ADVANTAGE : #/CMT# The method enables automatic recognition of defect pixel depending on the appropriate pixel value within the noise image, of the mean value of all pixel values and the middle deviation of the pixel values in a simple manner without additional effort, thus exhibiting smart repair function. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a photographic representation of a multiple dark images from which a signal image and a noise image are produced. 1 : Images.
