accreditation phantom,35 and the SedentexCT IQ phantom34) have been introduced for clinical CT scanners in the recent past. Even though these phantoms allow for measuring a broad range of IQ parameters and analysis of volume data is supported by commercial computer software (e.g., CT Au-toQA Lite, Iris QA, Frederick, MD, USA), they are not suited Methods: The SEDENTEXCT IQ phantom and Radia diagnostic software were employed. The phantom was scanned using one medical full-body CT and two dento-maxillo-facial cone beam CTs. The point spread function (PSF) insert in the SedentexCT IQ phantom (SedentexCT IQ, Leeds Test Objects Ltd., Boroughbridge, UK) was used to calculate the MTF. The PSF insert is made of a stainless steel wire (diameter: 0.25 mm) suspended in the air. Fig. 2: SedentexCT-IQ phantom for image quality evaluation. Methods and materials Three dental hybrid CBCT commercially available were investigated, hereinafter referred to as Device 1 , Device 2 and Device 3 .

The phantom was scanned using one medical full-body CT and two dentomaxillofacial cone beam CTs. 2020-02-11 · Using the SEDENTEXCT IQ Image Quality phantom, the CNR was calculated by ImageJ software. RESULTS: A reduction on the visibility of anatomical structures was seen under lower exposure parameters. However, for 84% of the protocols, visibility of anatomical structures remained acceptable even under some lower parameter settings. A cone beam computed tomography (CBCT) image quality phantom designed as a member of the sedentexct consortium. Download product brochure here: METHODS: The SEDENTEXCT IQ phantom and Radia diagnostic software were employed. The phantom was scanned using one medical full-body CT and two dentomaxillofacial cone beam CTs. The obtained images were imported to the Radia software, and the spatial resolution outputs were evaluated. Technical evaluation was performed with the SEDENTEXCT-IQ phantom.

A SEDENTEXCT IQ phantom is frequently employed for evaluating CBCT characteristics 4 in scientific studies and contains the various insert modules for analysing spatial resolution, contrast resolution, pixel intensity and beam hardening artefacts . However, to the best of our knowledge, there has been no study on the use of the Radia diagnostic software.

In or-der to identify the optimal method of MTF measurement, factors affecting the MTF were investigated using a 3-step Methods: The SEDENTEXCT IQ phantom and Radia diagnostic software were employed. The phantom was scanned using one medical full-body CT and two dento-maxillo-facial cone beam CTs. 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. The images obtained using a real skull phantom were evaluated for each diagnostic task by 6 oral and maxillofacial radiologists, and each setting was classified as acceptable or unacceptable based on those evaluations. 2016-03-11 The SEDENTEXCT project recommended that the QA program be mainly composed of six subjects including performance of the x-ray tube and generator, quantitative assessment of IQ, display screen performance, patient dose assessment, clinical IQ assessment, and clinical audit. 16 Image intensity values, uniformity, and artifacts are recommended for monthly testing, and the others are … SEDENTEXCT IQ DENTAL CBCT A PMMA cylinder (160 mm diameter) with recesses to house test inserts (fig. 1).

The PSF insert is made of a stainless steel wire (diameter: 0.25 mm) suspended in the air.

A protocol proposed by SEDENTEXCT, dose index 1 (DI1), was applied to dose measurements using a Carestream 9300 dental CBCT. Phantoms were positioned in the FOV to imitate clinical positioning.
