Verfahren zur Echtzeitkorrektur nicht funktionierender Pixel in der digitalen Radiographie

摘要

A method and program product for real-time correction of non-functioning pixels in digital radiography, where the method comprises: receiving a list of non-functioning pixels (100); determining which neighboring functioning pixels are needed to correct the non-functioning pixels (110); organizing those neighboring functioning pixels and corresponding non-functioning pixels into a plurality of groups by a number of pixels used to perform correction (120); and performing correction of data from non-functioning pixels within one of the plurality of groups and subsequently performing correction of data from non-functioning pixels within another one of the plurality of groups (130). Also, a method and program product for producing an accurate real-time map of non-functioning pixels in a detector panel for digital radiography, where the method comprises: determining a first list of non-functioning pixels found using an extended exposure mode of the detector panel; determining a second list of non-functioning pixels found using a real-time mode of the detector panel; and merging the first and second lists into a merged list of non-functioning pixels for the detector panel.
