In digital radiography, the transmitted x-ray beam recorded by a detector is first recorded as raw data related to the energy deposited in the sensitive region of each pixel. Raw data is then transformed to a 'For Processing' image by correcting for gain non-uniformity and bad pixels. ...

Digital image processing in neutron radiography These disturbing spots have to be removed by means of digital image processing. Several filters have been tested, but the results were insufficient. Therefore, a new threshold-median-mean value filter was designed and a proper code was... S Körner...
However, digital radiography also poses risks, such as unnoticed increases in patient dose and suboptimum image processing that may lead to suppression of diagnostic information. Advanced processing techniques, such as temporal subtraction, dual-energy subtraction and computer-aided detection (CAD) will ...
