BP¶
This is a CPU implementation of a simple backprojection algorithm for 2D data sets. It takes a projector and projection data as input, and returns the backprojection of this data.
Supported geometries: parallel, fanflat, fanflat_vec, matrix.
Configuration options¶
| name | type | description |
|---|---|---|
| cfg.ProjectorId | required | The astra_mex_projector ID of the projector. |
| cfg.ProjectionDataId | required | The astra_mex_data2d ID of the projection data |
| cfg.ReconstructionDataId | required | The astra_mex_data2d ID of the reconstruction data. The content of this data is overwritten. |
| cfg.option.SinogramMaskId | optional | If specified, the astra_mex_data2d ID of a projection-data-sized volume to be used as a mask. |
| cfg.option.ReconstructionMaskId | optional | If specified, the astra_mex_data2d ID of a volume-data-sized volume to be used as a mask. |
