XFCT is a novel method for the early cancer detection. Increasing concentration of contrast agents and incident X-rays' energy were used to improve detecting accuracy, which greatly increased the prevalence of contrast-induced nephropathy. Therefore, this research explores the adaptive contrast agents and uses Geant4 to simulate the imaging conditions of Pt, Bi, Gd, Ru, and Au for searching the lowest detectable concentration based on the fast multi-pinhole collimated XFCT (fmpc-XFCT) imagingdoi:10.3389/fphy.2021.686988 fatcat:einpzjcsfndb3get4pjkr2pzd4
