3D less than 2D Pan + Ceph
Martin Palomo give a presentation showing how CBCT scanners have dropped radiation dosage.
The technology used to drop 3D dosage apparently might not be applicable to 2D scans, so in
Toni Magni asked if it's possible to use the same technology used to reduce 3D radiation to reduce 2D radiation. 3D is based on redundant information, while 2D is a one shot deal, so it's harder to improve technology on a system that doesn't have room for improvement. So, the group agreed that it's not possible to reduce 2D further.
Franco Magni suggests that the CBCT PAN at low dosage is not clinically acceptable, as it's resolution is too low.
Manish shows some real patient data of a QuickScan+ at 4.8s (very low dosage and resolution). Pano does not do justice in assessment to pathology for sure. He's not looking at pano's anymore for pathologies. He uses 3D reconstruction only.
Conclusion
The group convened that in 2014 CBCT now replaces Pan screening image for orthodontics.
