Abstract:We introduce a new calibration method for Dual Energy CT (DECT) based on Material Decomposition (MD) maps, specifically iodine and water MD maps. The aim of this method is to provide the first DECT calibration based on MD maps. The experiments were carried out using a General Electric (GE) Revolution CT scanner with ultra-fast kV switching and used a Density Phantom by GAMMEX for calibration and evaluation.

The calibration process involves several steps. First, we tested the ability of MD valu… Show more
