A new phantom developed to test the ATCM performance of chest CT scanners

Abstract: In this study, a new ATCM phantom was developed to test the performance of the automatic tube current modulation (ATCM) of computed tomography (CT) scanners.. Based on the Chinese reference man and Monte Carlo simulations of x-ray attenuation, a more realistic ATCM phantom made of polymethyl methacrylate was developed. The phantom has a length of 20 cm, and it can be used to measure the dose profile along the central axis using 19 real-time MOSFET detectors. The image noise can be calculated slice by slice in … Show more

“…Based on the CT scanner model developed by Huang et al [27,28] and the individually voxelized phantoms built above, the organ doses for each patient were simulated by using MCNPX 2.4.0. In the CT model, 16 X-ray sources uniformly distributed along the rack were set to simulate the helical CT scanning.…”
