2017-03-07 · a new emerging dental X-ray modality (SEDENTEXCT) image quality (IQ) phantom in CT, and to evaluate its validity. 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 SedentexCT IQ phantom (Leeds Test Objects Ltd, Borough-bridge, UK) was used to investigate the relationship between contrast-to-noise ratio (CNR) and dose–area product (DAP). 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. 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.

Images obtained using the CBCT machine were saved in the Digital Imaging and Communications in Medicine (DICOM) format. Physical measurement of the image quality To measure the physical image quality, CBCT images of a SedentexCT IQ phantom were obtained under 28 expo- 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. IQ was assessed by scanning a SEDENTEXCT IQ phantom, and images were analyzed in ImageJ. Dose index 1 was obtained using a thimble ionization chamber and SEDENTEXCT DI phantom.

A protocol proposed by SEDENTEXCT, dose index 1 (DI1), was applied to dose measurements whole image of the SedentexCT IQ phantom (SedentexCT IQ, Leeds Test Objects Ltd., North Yorkshire, UK). To obtain images with different image qualities, 28 combina-tions of 4 different tube voltages and 7 different tube cur-rents were used for a SedentexCT IQ phantom and a real skull phantom (78, 80, 85, and 90 kVp; and 2, 3, 4, 5, 6, 7, and 8 mA).
