Rotating Projection Based Localizer Radiograph: Attenuation Calculation Optimization And Patient Automatic Centering With Parallel-Beam Projection Scheme
MEDICAL IMAGING 2021: PHYSICS OF MEDICAL IMAGING(2021)
Abstract
Attenuation information from Localizer Radiograph (LR) is the basis for Automatic Exposure Control. However, the total achievable dose optimization could be significantly affected by either LR based attenuation calculation or patient positioning. To avoid those aspects, we proposed an integrated procedure for more robust and accurate attenuation calculation as well as possible automatic patient centering combined with the Rotating Projection base Localizer Radiograph (RPLR). A 3D attenuation map with more accurate attenuation information and automatic patient centering can be realized with one pre-view scan, so that a complete automatic workflow with always optimized dose modulation can be enabled.
