Image quality evaluation of small FOV and large FOV CBCT devices for oral and maxillofacial radiology.

Objectives: Quantitative and qualitative image quality evaluation of two different dental CBCT scanners.

Methods: Two CBCT systems were evaluated in this study: one small field-of-view (FOV) (50-mm diameter) system that also allows two-dimensional (2D) dental panoramic imaging and one large FOV CBCT system (60-180-mm diameter). These devices were all tested with installed acquisition default modes and proprietary reconstruction software, enabling high-resolution bone imaging.
