Abstract
This thesis describes a system model of the imaging chain of the Statscan slit scanning full body radiography machine. A Cascaded Linear-Systems model of the detector was developed and the theoretical DQE, MTF and NPS were compared to measure values of the RQA7 beam quality described in IEC 6222-1. The effect on Detector DQE of various system parameters such as coupling efficiency, CCD noise and pixel binning was quantified. Also detector performance for varous thicknesses of Gd2O2S:Tb screens were analysed.
