Objectives The aim of this study is to evaluate the technical image quality and radiation dose of the DentiiScan 2.0 cone-beam computed tomography (CBCT) scanner before widespread clinical use. Materials and methods Image quality was measured for 4 scanning protocols of the DentiiScan 2.0, using 2 dedicated test objects: the SEDENTEXCT IQ phantom and the QRM-ConeBeam phantom. The following image quality parameters were evaluated: contrast-detail, contrast-to-noise ratio (CNR), spatial resolution, grey value uniformity, metal artefacts, and geometric accuracy. Radiation dose was measured using a calibrated ionization chamber placed at the isocenter of rotation, allowing for the calculation of the dose-area …
