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. Dental Science research project is used in air, the through-holes (diameter: 0.2–1.0mm) are filled with air, whereas the SedentexCT IQ contrast resolution phan-toms require the insides of some of their holes (diam-eter: 1.0–5.0mm) to be filled with one of five different substances.

The SEDENTEXCT developed phantoms to perform various measurements specific to dental CBCT. Some of the measurements are considered essential to be tested by the medical physicist while other measurements are recommended (10). The SEDENTEXCT image quality (IQ) phantom was manufactured by (SEDENTEXCT IQ; Leeds Test Objects Ltd, Boroughbridge, UK).
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

Methods: The SEDENTEXCT IQ phantom and Radia dia gnostic software were emplo yed. 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 a variable field of view (FOV) 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 the efficacy of dental cbct for root fracture diagnosis in non-endodontically treated permanent anterior teeth.
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. 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
The aim of this study was to determine optimized kV settings for paediatric acquisitions for a dental CBCT device.

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). Methods: Image quality and dose measurements were done on a variable field of view (FOV) dental CBCT (Carestream 9300). X-ray parameters for clinical settings were adjustable for 2-10 mA, 60-90 kVp, and two optional voxel size values, with fixed time for each protocol and FOV. SEDENTEXCT IQ.

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. CBCT images of a real skull phantom and a SedentexCT IQ phantom were acquired under different exposure conditions (one Dinnova3 CBCT scanner, 60-110 kV and 4-10 mA).
