Abstract

We propose a novel electron density imaging technique based on a Compton scattered X-ray CT (CSX-CT) technique. We design fundamental configuration of the CSX-CT system, which consists of a fan-shaped X-ray beam, two-dimensional sensors for scattered X-ray detection, parallel plate collimators for limitation of the direction of scattered X-rays and a line sensor for the transmission of X-ray CT (TX-CT). An image obtained by the TX-CT can be used to correct the attenuation effect of scattered X-rays. Through Monte Carlo simulation modeling studies of the CSX-CT system, we demonstrate that the utilization of the information of scattered X-rays is useful to obtain the electron density image. We additionally confirm that the medical exposure irradiated in the CSX-CT is estimated to be lower than the maximum dose recommended in the guideline of some committees.
