Identification of dental root canals and their medial line from micro-CT and cone-beam CT records
BACKGROUND Shape of the dental root canal is highly patient specific. Automated identification methods of the medial line of dental root canals and the reproduction of their 3D shape can be beneficial for planning endodontic interventions as severely curved root canals or multi-rooted teeth may pose treatment challenges. Accurate shape information of the root canals may also be used by manufact...
متن کاملIdentification of the Dental Root Canal from Micro-CT Records Using 3D Curve Skeleton Extraction
This paper presents a novel image processing procedure dedicated to the automated detection of the medial axis of the root canal from dental micro CT records. The 3D model of root canal is built up from several hundreds of parallel cross sections, using image enhancement and an enhanced fuzzy cmeans based partitioning, center point detection in the segmented slice, three dimensional inner surfa...
متن کاملGeometric Parameters Estimation and Calibration in Cone-Beam Micro-CT
The quality of Computed Tomography (CT) images crucially depends on the precise knowledge of the scanner geometry. Therefore, it is necessary to estimate and calibrate the misalignments before image acquisition. In this paper, a Two-Piece-Ball (TPB) phantom is used to estimate a set of parameters that describe the geometry of a cone-beam CT system. Only multiple projections of the TPB phantom a...
متن کاملCone beam CT for dental and maxillofacial imaging: dose matters.
The widespread use of cone-beam CT (CBCT) in dentistry has led to increasing concern regarding justification and optimisation of CBCT exposures. When used as a substitute to multidetector CT (MDCT), CBCT can lead to significant dose reduction; however, low-dose protocols of current-generation MDCTs show that there is an overlap between CBCT and MDCT doses. More importantly, although the 3D info...

the highest success rates for any orthopedic medical restorative process. According to Scott D. Ganz, DMD, Maxillofacial Prosthodontist, these success rates perhaps explain one of the barriers to clinicians ordering more computed tomography (CT) scans for prospective implant patients. He explains, however, that “CT imaging can help clinicians improve all aspects of implant reconstruction, inclu...
