The European Commission's Evidence Based Guidelines prepared by the SEDENTEXCT Project Consortium will be summarised, and (in)appropriate use of CBCT will be illustrated for various dental applications. © The Author 2015. Published by Oxford University Press. The SEDENTEXCT (Safety and Efficacy of a New and Emerging Dental X-ray Modality) project was a multicentric collaboration, funded by the European Atomic Energy Community's Seventh Framework Programme. Materials and Methods: CBCT images of a SedentexCT IQ phantom and a real skull phantom were obtained under different combinations of tube voltage and tube current (Alphard 3030 CBCT scanner, 78-90 kVp and 2-8 mA). The images obtained using a SedentexCT IQ phantom were analyzed technically, and the physical factors of In this study, the IQ and radiation dose of a dental CBCT machine (CS 9300, Carestream Dental LLC, Atlanta, Georgia) were evaluated using IQ and dose index (DI) phantoms developed by Leeds Test Objects Ltd. (SEDENTEXCT, Boroughbridge, UK) for dental CBCT machines. Both phan-toms are head-sized cylinders (160-mm diameter by 162-mm SEDENTEXCT was a collaborative project that aimed to acquire key information necessary for sound and scientifically based clinical use of Cone Beam Computed Tomography (CBCT) in dental and maxillofacial imaging.

CONE-BEAM CT: A PARADIGM SHIFT IN DENTAL IMAGING. Cone-beam CT (CBCT) was introduced into dental imaging more than 15 y ago. It has proved to be a useful modality for imaging of the hard tissues and air cavities of the dental and ear–nose–throat areas. 2016-11-02 · 426 West Duarte Road Monrovia, California 91016, USA Phone :1-626-357-7921 Fax :1-626-357-8863 CBCT images of a SedentexCT IQ phantom and a real skull phantom were obtained under different combinations of tube voltage and tube current (Alphard 3030 CBCT scanner, 78–90 kVp and 2–8 mA). The images obtained using a SedentexCT IQ phantom were analyzed technically, and the physical factors of image noise, contrast resolution, spatial resolution, and metal artifacts were measured.

Results: The automated IQ evaluation of volume data sets of the dental CBCT system was achieved with the proposed phantom requiring only one scan for the determination of all desired parameters. Typically, less than 5 min were needed for phantom set-up, scanning, and data analysis.

Łatwy dostęp do kalendarza, szybkie i skuteczne wykonywanie zadań to tylko kilka z niewielu zalet tego programu. Leeds Test Objects specialises in the design and manufacture of innovative medical imaging quality assurance test objects, known as medical imaging phantoms, and analysis software.

Subjective image quality assessment was achieved using a small adult skull phantom (RANDO®; The Phantom Laboratory, Salem, NY) for the same range of exposure settings.

The SEDENTEXCT project (1 January 2008 - 30 June 2011) is focused on enhanced safety and efficacy in the use of cone beam computed tomography (CBCT) in dental and maxillofacial radiology. In particular, the work plan aims to find solutions to the challenge of this new X-ray imaging modality becoming available to the large community of dentists, medical physicists and other stakeholders in Europe.
