Detailed Description

This implements the ForwardProjectorByBin interface, given any ProjMatrixByBin object

It stores a shared_ptr to a ProjMatrixByBin object, which will be used to get the relevant elements of the projection matrix.

Member Function Documentation

◆ set_up()

void stir::ForwardProjectorByBinUsingProjMatrixByBin::set_up ( const shared_ptr< const ProjDataInfo > &  proj_data_info_ptr,
const shared_ptr< const DiscretisedDensity< 3, float >> &  density_info_ptr 
)
overridevirtual

Stores all necessary geometric info.

Note that the density_info_ptr is not stored in this object. It's only used to get some info on sizes etc.

Implements stir::ForwardProjectorByBin.
