Simulated and measured system sensitivities as function of the source-collimator distance for \(^{177}{\mathrm {Lu}}\) for the LEHR and MEGP collimators and energy windows positioned over 55 keV, 113 keV and 208 keV. Simulated data are connected with straight lines, for measured data a function is fitted. Simulated sensitivities are separated into sub-components based on the emission energy and events in the photon transport, including collimated primary (geom. primary), phantom scatter (phan. sca.), collimator penetration (pen.), collimator scatter (col. sca.) and collimator x-rays (x-rays). Components with a low contribution are grouped together (other)
