TU‐EF‐204‐08: Dose Efficiency of Added Beam‐Shaping Filter with Varied Attenuation Levels in Lung‐Cancer Screening CT
Abstract
Purpose: Added filtration such as tin filter has the potential to improve dose efficiency of x‐ray beam in lung‐cancer screening CT. However, dose efficiency with added beam filtration is highly dependent on patient attenuation level. In this phantom study, we evaluated the image quality at different tube voltages with and without added tin filter when attenuation level varies. Methods: A 30 × 20 cm anthropomorphic thorax phantom with three...
