Coolens C, et al. - In the present study, researchers intended to develop a solid calibration phantom for routine contrast-enhanced (CE) CT quality assurance and examined the sensitivity of CECT to organ motion, as well as describing a volumetric CT scanner for CECT. For this investigation, CECT calibration phantom consisting of an acrylic uniform cylinder containing multiple capsules of varying diameters and orientations was designed and built. Using the CECT phantom, routine commissioning tests such as uniformity, spatial resolution and image noise were successfully determined. The data presented in this work showed a new robust contrast calibration phantom was developed and used to assess the performance of a 320-slice volumetric CT scanner for DCE-CT.
