Hello users, I have read Flat field image correction using dark ( projection with CT-off, detector-on ) and bright ( projection with CT-on, detector-on and no object in between CT and detector ) images procured before scanning any substance.
correction = log (bright image) - log ( projection-dark image ); // for all projections This pre-processed images are then fed to FDK algorithm. Did someone here tried this method? If I want to implement this, do I have to write a separate class for this? Any suggestions for that? PS: Presently I am using LUTbasedVariableI0RawToAttenuationImageFilter and I am getting reasonably good output. When i implemented FDK in MATLAB i used this flat field correction and result was good. So I want to know the impact with RTK. Thanks and Regards, AMJAD N
