Mean gray values agreed within 93.5% to 99.7% across the images, with pixel-to-pixel fluctuations of 6% to 12.5%, with poorer uniformity 2015-10-01 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. 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. Both phantoms can be mounted on a … A cone beam computed tomography (CBCT) image quality phantom designed as a member of the sedentexct consortium.

Dose index 1 was obtained using a thimble ionization chamber and SEDENTEXCT DI phantom.

In or-der to identify the optimal method of MTF measurement, factors affecting the MTF were investigated using a 3-step 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. 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).
