COMPARATIVE STUDY OF IMAGE QUALITY FOR MSCT AND CBCT SCANNERS FOR DENTOMAXILLOFACIAL RADIOLOGY APPLI
June 29th, 2008 | by admin |COMPARATIVE STUDY OF IMAGE QUALITY FOR MSCT AND CBCT SCANNERS FOR DENTOMAXILLOFACIAL RADIOLOGY APPLICATIONS.
The image quality of four cone-beam computed tomography (CBCT) scanners dedicated for dentomaxillofacial imaging and one multi-slice computed tomgoraphy (MSCT) scanner was compared. For the MSCT scanner, a clinical and a low-dose protocol for oral indications were evaluated. The image quality was assessed by dedicated software that allows an automated analysis of accuracy measurements and evaluation of metal artefacts on two image quality phantoms. Bone was segmented with sub-millimetre accuracyin all scanners.
