Cone 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...
متن کاملSegmentation of Large Periapical Lesions toward Dental Computer- Aided Diagnosis in Cone-Beam CT Scans
This paper presents an experimental study for assessing the applicability of general-purpose 3D segmentation algorithms for analyzing dental periapical lesions in cone-beam computed tomography (CBCT) scans. In the field of Endodontics, clinical studies have been unable to determine if a periapical granuloma can heal with non-surgical methods. Addressing this issue, Simon et al. recently propose...
متن کاملVolume-of-change cone-beam CT for image-guided surgery.
C-arm cone-beam CT (CBCT) can provide intraoperative 3D imaging capability for surgical guidance, but workflow and radiation dose are the significant barriers to broad utilization. One main reason is that each 3D image acquisition requires a complete scan with a full radiation dose to present a completely new 3D image every time. In this paper, we propose to utilize patient-specific CT or CBCT ...
متن کاملIntraoperative cone-beam CT for guidance of temporal bone surgery.
OBJECTIVES To describe our preclinical experience with Cone Beam CT (CBCT) in image-guided surgery of the temporal bone. STUDY DESIGN AND SETTINGS A mobile isocentric C-arm (PowerMobil, Siemens Medical Systems, Erlangen, Germany) modified to include a flat-panel detector (Varian Imaging Products, Palo Alto, CA) and a motorized orbit was developed to acquire multiple projections in rotation ab...
متن کاملSuperimposition of 3D cone-beam CT models in orthognathic surgery.
INTRODUCTION: Limitations of 2D quantitative and qualitative evaluation of surgical displacements can be overcome by CBCT and three-dimensional imaging tools. OBJECTIVES: The method described in this study allows the assessment of changes in the condyles, rami, chin, maxilla and dentition by the comparison of CBCT scans before and after orthognathic surgery. METHODS: 3D models are built and s...
