Detailed Description

Compute a mask for the "tails" in the sinogram.

This computes the outer part of the projection data that does not receive any (unscattered) contributions from inside the body. Its normal input is a projection data with attenuation-correction factors (ACFs). We take a threshold as parameter (which should be a bit larger than 1). Along each line in the sinogram, we search from the edges until we find the first bin above the threshold. We then go back a few bins (as set by safety-margin). All bins from the edge until this point are included in the mask.

As from 23 July 2016, the functionality of this executable was transfered in a new class CreateTailMaskFromACFs. This made possible to use par file to initiliase the process and use it from within some other code.

In the latter case, where the output will be used from some other code the output file can be omitted, in order to avoid unnecessary outputs.
