[Rtk-users] Forward projector output discrepancy

[Brandon LaCava]

Hi. I'm getting vastly different outputs from the Joseph forward projector
vs. Cuda, given the exact same inputs. I'm hoping someone has any idea why.
Here's some sample images:

1. Joseph

2. Cuda

The general orientation looks the same, but the FOV is wildly different.
I've attached a small stripped-down rtkforwardprojections.cxx which was
used to generate these images. Literally the only difference between the
two runs is the projector type. Everything else is identical. Input is from
a CT MHD, output to PNG. Same result on Windows and Linux.

Any help here would be appreciated. Thanks!

Cheers,
Brandon
