Spatial resolution measurements by Radia diagnostic software with SEDENTEXCT image quality phantom in cone beam CT for dental use

Objectives:We aimed to employ the Radia diagnostic software with the Safety and Efficacy of a New Emerging Dental X-ray Modality (SEDENTEXCT) image quality (IQ) phantom in computed tomography (CT), and to evaluate its validity.Methods:The SEDENTEXCT IQ phantom and Radia diagnostic software were employed. The phantom was scanned using one medical full-body CT and two dento-maxillo-facial cone beam CTs. The obtained images were imported to the Radia software, and the spatial resolution outputs were evaluated. The oversampling method was employed using our original wire phantom as a reference. The resultant modulation transfer function (MTF) curves were compared. The null hypothesis was that MTF curves generated using both methods would be in agreement. One-way analysis of variance tests were applied to the f50 and f10 values from the MTF curves. The f10 values were subjectively confirmed by observing the line pair modules.Results:The Radia software reported the MTF curves on the XY-plane of the CT scans, bu...
