説明

We evaluated the accuracy of linear measurements in dental CBCT­based images for various sites in the field of view (FOV). We used a phantom of 30 stacked commercially available CD­R disks. The phantom was scanned with two cone­beam computed tomogra­ phy (CBCT) units, a Kyocera Prevista Uni­3D MultiOS and a Morita 3D Accuitomo F 17,and linear measurements were obtained with a digital caliper. The error characteristics were different for each device. There were similar errors on the edges of the FOV at 90 kV. Measurement errors in the upper and lower regions of the FOV tended to be slightly larger than in the middle. It is important to understand that the accuracy of linear meas­ urements in CBCT images varies depending on their location in the FOV.
