SEDENTEXCT Workshop on dental Cone Beam CT Thursday 31 March 2011, 10am to 5pm Venue: Leeds City Museum, Leeds, United Kingdom. In the last ten years, dental Cone Beam Computed Tomography (CBCT) has risen in prominence as an imaging technique in dentistry and as a subject of controversy.
Purpose: To characterize the performance of cone beam CT (CBCT) used in dentistry, investigating quantitatively the image quality and radiation dose during dental CBCT over different settings for partial rotation of the x-ray tube. Methods: Image quality and dose measurements were done on …
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. 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.

2020-04-24 Inom odontologisk såväl som inom medicinsk radiologi sker en snabb utveckling av nya tekniker. Nya metoder för att kunna diagnosticera och följa sjukdomsförlopp över tid introduceras. Cone-Beam Com for 3D Accuitomo® 170 CBCT scanner (J. Morita, Kyoto, Japan) using 12 different scanning protocols for assessment of periodontal structures. The SedentexCT IQ phantom (Leeds Test Objects Ltd, Boroughbridge, UK) was used to investigate the relationship between contrast-to-noise ratio (CNR) and dose–area product (DAP).
The IQ and DI phantoms (SedentexCT IQ, Leeds Test Objects Ltd., Boroughbridge, UK) are polymethyl methacrylate (PMMA) cylinders, 160 mm in diameter, and 162 mm in height, which approximate the radiographic properties of an adult head. Both phantoms can be mounted on a …

Published by Oxford University Press. The investigators also gathered CBCT images of a tangible skull ghost and a SedentexCT IQ image not evoked by actual stimuli, under diverse conditions of presentation making use of a Dinnova3 CBCT scanner at 60-110 kV and 4-10 mA.
Even though a few previous studies [17–19] and special working groups (e.g.
