Image quality vs radiation dose of four cone beam computed tomography scanners

To evaluate image quality by examining segmentation accuracy and assess radiation dose for cone beam CT (CBCT) scanners. A skull phantom, scanned by a laser scanner, and a contrast phantom were used to evaluate segmentation accuracy. The contrast phantom consisted of a polymethyl methacrylate (PMMA)...
