Detailed Description

The loader stage for offline data processing.

This stage gets the paths to the input files and loads data sinogram by sinogram. Hence, the the lower limit of the reconstruction speed is given by the bandwidth of the storage system. Furthermore, this method leads to low memory consumption.
