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.
SEDENTEX-CT IQ Phantom The SEDENTEXCT IQ phantom used was developed Yorkshire, United Kingdom) for CBCT quality assur-ance testing and was centered on a tripod in each CBCT machine tested in this protocol (Figure 1). The phantom is a polymethyl methacrylate (PMMA) cylinder with a 16 cm diameter. 8 The phantom can be filled with six rows
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 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. 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.

The phantom is 176 mm in height and 160 mm in diameter. There are five contrast resolution inserts with different materials [aluminium (Al), polytetrafluoroethylene (PTFE), low density polyethylene (LDPE), air and delrin]. 2017-03-07 · 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 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.

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.
