[Rtk-users] DRR image generation from 3D CT

[Isuru Suranga Wijesinghe]

Hi,

I have built rtkforwardprojections code. And pass the appropriate
parameters to the generated exe from the command line as below.
But there is nothing in the output location. I have attached herewith my
geomtry.xml as well.

D:/RTK/Build/bin/Release>rtkforwardprojections -g D:/geomtry.xml -i
D:\\Subject_01\\CT\\PhaseImage_01.mha -o D:/_rtk_output.png
