Abstract

This work provides the characterization of the spectral response of caesium iodide flat panel detectors from several manufacturers. The analysis is done for the following model flat panels: 12 Flashpad from General Electric, 6 DRX Plus 4343C from Carestream, 4 CXDI-410 Wireless from Canon, 4 FDR D-EVO II from Fujifilm Corporation and 2 Pixium EZ from Trixell. The characterization is carried out by measuring Exposure Index – incident air kerma ratios for beams with different spectrum and results are provided for each flat panel model. Furthermore, it is proposed a methodology to verify the correct configuration of the anatomic menu.
Key words: Exposure Index, Digital Radiogra
