PURPOSE The aim of this work was to implement, validate, and compare two procedures for routine image quality (IQ) assurance in dental cone-beam computed tomography (CBCT): 1. the German standard DIN 6868 - 161 introduced in 2013 and 2. the established standard IEC 61,223 - 3-5 for clinical CT x-ray equipment referenced as "DIN" and "IEC" below. MATERIALS AND METHODS The approximated in-plane modulation transfer function (MTF), the contrast-to-noise indicator (CNI), and the uniformity… CONTINUE READING
