Detailed Description

This class is designed to manage the computation of the sensitivity image.

The sensitivity computation can be done in two ways:
(i) using a normalization data file if provided, where the loop for computation will be done on all events included in the datafile, with included normalization factors;
(ii) if no normalization file is provided, using a loop on all scanner elements.
A mumap in cm-1 can also be provided in order to include the attenuation correction in the sensitivity image.
