Phantom investigation of 3D motion-dependent volume aliasing during CT simulation for radiation therapy planning
PURPOSE:To quantify volumetric and positional aliasing during non-gated fast- and slow-scan acquisition CT in the presence of 3D target motion.METHODS:Single-slice fast, single-slice slow, and multi-slice fast scan helical CTs were acquired of dynamic spherical targets (1 and 3.15 cm in diameter), e...
