Description
Data of "Multi-institutional study on image quality for a novel CBCT solution on O-ring linac". This work presents a multi-institutional study on image quality provided by a novel cone beam computed tomography (CBCT). The main goal is to investigate the consistency of imaging performance across multiple institutions. Methods: Phantoms for measuring relative electron density (RED) and image quality were sent to six institutions for imaging on Ethos and Halcyon units equipped with HyperSight CBCT. The imaging protocols included tube potential from 100 to 140 kVp and exposure from 80 to 800 mAs. Imaging performance was evaluated with regard to RED versus Hounsfield Units (HU), uniformity, contrast-to-noise ratio (CNR), slice thickness, circular symmetry, Modulation Transfer Function (MTF), and spatial resolution (among other parameters).

Steps to reproduce
Please make a note of the following information: - The image quality data with the CatPhan 604 is specified in the protocols folders. - The results for Relative Electron Densities vs Hounsfield Units are provided in the REDvsHU folder for all protocols. - RED0 and RED1 correspond to Relative Electron Densities greater than or equal to 1, and lower than or equal to 1, respectively. This rationale is also applied to different parameters such as Advance Electronic Density (AED); AED0 and AED1. - For more details, please refer to the manuscript.
