scnmshft 1.1 © 2003 by Turku PET Centre

Shifts the sinogram rows to set the maximum value of each row to the middle. Sinogram data outside specified FOV (mm) from the middle of the scanner are set to zero before searching for maximum and shifting. If filename for projection sum curves is specified, the views of each sinogram is summed and written in DFT format as a function of distance (mm) from the middle of the sacnner. Usage: scnmshft <Sinogram> <FOV> <Output sinogram> [Projection sum datafile] Note that transaxial FOV in sinogram main header has to be correctly set. Currently supports ECAT 6.3 and 7.x 2D sinogram formats.
