FP3D_CUDA

This is a GPU implementation of a simple forward projection algorithm for 3D data sets. It takes a volume as input, and returns the projection data.

Supported geometries: parallel3d, parallel3d_vec, cone, cone_vec.

Configuration options

name

type

description

cfg.ProjectionDataId

required

The astra_mex_data2d ID of the projection data. The forward projection is added to this data.

cfg.VolumeDataId

required

The astra_mex_data2d ID of the reconstruction data.

cfg.option.DetectorSuperSampling

optional

Specifies the amount of detector supersampling, i.e., how many rays are cast per detector.

cfg.option.GPUindex

optional

Specifies which GPU to use. Default = 0.
