Default Projector in Recon

Dear all,

What is the default projector of the castor-recon command if we do not define it? Thanks!


Dear Xinjie,

The default projector is an incremental version of the Siddon projector, based on:
F. Jacobs et al, “A fast algorithm to calculate the exact radiological path through a pixel or voxel space”, J. Comput. Inf. Technol., vol. 6, pp. 89-94, 1998

You can have some information about the implemented projectors by using -help-projm in the command line options of castor-recon.
