From Simulations to Clinical Practice: The Impact of 4D XCAT Phantoms on Imaging Technologies

Author(s) Fadwa Joma Abuhbail
Country India
Abstract The purpose of the four-dimensional (4D) eXtended CArdiac-Torso (XCAT) phantom series was to create precise computer models of human anatomy and physiology. The XCAT series includes parameterised models for the respiratory and cardiac movements and includes a large population of phantoms ranging in age from birth to adult. Numerous body sizes, various anatomies, cardiac or respiratory motions or patterns, patient positions and orientations, and spatial resolutions can all be mimicked with the XCAT thanks to its very flexible design. Because of this, XCAT phantoms are becoming increasingly used in biomedical imaging research.They can offer a virtual patient base from which imaging instrumentation, data acquisition, methodologies, and image reconstruction and processing methods can be statistically evaluated and improved. This can result in better picture quality and more precise clinical diagnoses. Radiation dosimetry, radiation therapy, medical device design, and even the security and defence sector have found extensive applications for the phantoms. This review study focusses on a few specific applications of the XCAT phantoms in biomedical imaging and related sectors. We demonstrate the growing significance of computer simulation and computerised phantoms in the scientific community with these instances.
