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. 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.

SedentexCT IQ. SedentexCTIQ consists of 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.

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. 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.

Maxillofacial cone beam computed tomography CBCT

To measure the contrast-to-noise ratio (CNR), the SedentexCT IQ Dec 5, 2014 CBCT images of a real skull phantom and a SedentexCT IQ phantom they are still higher than those of conventional dental radiography. One objective of the SEDENTEXCT project has been to review the current literature on CBCT and to derive useful guidelines that will clarify those clinical PMMA cylinder phantom dedicated to the CBCT system verification.

1).

The phantom was scanned using one medical full-body CT and two dentomaxillofacial cone beam CTs. This paper provides an overview of justification and optimisation issues in dental and maxillofacial CBCT. 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.
