Reducing radiation dose to selected organs by selecting the tube start angle in MDCT helical scans: A Monte Carlo based study
Purpose: Previous work has demonstrated that there are significant dose variations with a sinusoidal pattern on the peripheral of a CTDI 32 cm phantom or on the surface of an anthropomorphic phantom when helical CT scanning is performed, resulting in the creation of “hot” spots or “cold” spots. The...
