Introduction Spectral shaping aims to narrow the X-ray spectrum of clinical CT. The aim of this study was to determine the image quality and the extent of radiation dose reduction that can be achieved by tin prefiltration for parasinus CT. Methods All scans were performed with a third generation dual-source CT scanner. A study protocol was designed using 100 kV tube voltage with tin prefiltration...
Objectives Shaping the energy spectrum of the X-ray beam has been shown to be beneficial in low-dose CT. This study’s aim was to investigate dose and image quality of tin filtration at 100 kV for pre-operative planning in low-dose paranasal CT imaging in a large patient cohort. Methods In a prospective trial, 129 patients were included. 64 patients were randomly assigned to the study protocol (100 kV...
