SEDENTEXCT IQ DENTAL CBCT A PMMA cylinder (160 mm diameter) with recesses to house test inserts (fig. 1). Within the body of the cylinder are features for the following tests; Noise/Uniformity - The lower section of the phantom is uniform PMMA (density 1.20 +/- 1.00%) Geometric Distortion - An array of 2.0 mm diameter, 3.0 mm deep Air
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. Our phantoms are used worldwide to ensure the safety and image quality of X-ray (including fluoroscopy, radiography, mammography and dental), MRI, CT, nuclear medicine 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. 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.

Pixel Intensity (Air) Pixel intensity (Aluminum) Pixel intensity (HA 50) Pixel intensity (HA 100) Pixel intensity (HA 200) PSF: The radiation dose in CBCT will be briefly reviewed. 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.
and SEDENTEXCT, a decision was taken to collaborate in the development of a set of “Basic Principles” for the use of dental CBCT. A Guideline Development Panel was formed to develop a set of draft statements using existing EU Directives and Guidelines on Radiation Protection.
Within the body of the cylinder are features for the following tests; Noise/Uniformity - The lower section of the phantom is uniform PMMA (density 1.20 +/- 1.00%) Geometric Distortion - An array of 2.0 mm diameter, 3.0 mm deep Air The aim of this study was to determine optimized kV settings for paediatric acquisitions for a dental CBCT device. METHODS: Clinical and quantitative evaluations of image quality were performed using 5 and 10 years old (y/o) anthropomorphic phantoms. Technical evaluation was performed with the SEDENTEXCT-IQ phantom.

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.
Methods: Image quality and dose measurements were done on a variable field of view (FOV) dental CBCT (Carestream 9300).
