[Rtk-users] Half Fan dataset

[Simon Rit]

Hi,
It's easy to generate, you need to offset your detector, either via the RTK
geometry or by setting the first coordinate of the origin of your
projection to something which makes the projection uncentered. For example,
in the geometry :
rtksimulatedgeometry -n 180 --proj_iso_x 100 -o g
rtkprojectshepploganphantom -g g -o proj.mha
rtkfdk -p . -g g -r proj.mha -o fdk.mha
You can simulate from a CT image by following this example
