![]() NCICT features two computation modes: Graphical User Interface (GUI) mode and Batch Calculation mode. NCICT is available for multiple platforms, including Windows, Mac, and LINUX. ![]() NCICT uses a comprehensive pre-calculated dose database, so the program does not use up many computing resources on a user's computer. ![]() Users do not need an internet connection to upload sensitive patient data to a central server. NCICT is a standalone software that runs on a personal computer. NCICT incorporates a state-of-the-art library of phantoms that represent just about any patient, including the International Commission on Radiological Protection (ICRP) reference pediatric and adult phantom series, a library of 370 pediatric and adult male and female phantoms at various heights and weights, and eight pregnant phantoms containing detailed fetus models at various gestations 6. The simulated dose results for pediatric and adult phantoms have been rigorously validated through comparison with experimental measurements conducted using physical anthropomorphic phantoms combined with dosimeters 3-5. NCICT combines several cutting-edge technologies, including a library of advanced computational human phantoms, the detailed simulation of x-rays from a reference CT scanner, and a user-friendly graphical interface. The program provides absorbed doses to major radiosensitive organs and tissues calculated using the characteristics of patients and CT scan parameters. ![]() NCICT, the National Cancer Institute dosimetry system for Computed Tomography 1-2 is a comprehensive cutting-edge CT organ dose calculator. To address this public health concern, it is important to have tools to assess and monitor radiation exposures from CT scans. Over the last three decades, the number of computed tomography (CT) examinations conducted annually has grown exponentially such that CT imaging currently represents about a quarter of the collective effective radiation dose received by the U.S. ![]()
