Measurement of physical image quality can serve as a foothold for future studies on the quality control of various cone bean computed tomography 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. 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. structures. The SedentexCT IQ phantom (Leeds Test Objects Ltd, Boroughbridge, UK) was used to investigate the relationship between contrast-to-noise ratio (CNR) and dose–area product (DAP).

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. a new emerging dental X-ray modality (SEDENTEXCT) image quality (IQ) phantom in CT, and to evaluate its validity.

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.

A cone beam computed tomography (CBCT) image quality phantom designed as a member of the sedentexct consortium. Download product brochure here:

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].

Subjective image quality assessment was achieved using a small adult skull phantom (RANDO ®; The Phantom Laboratory, Salem, NY) for CBCT images of a SedentexCT IQ phantom and a real skull phantom were obtained under different combinations of tube voltage and tube current (Alphard 3030 CBCT scanner, 78–90 kVp and 2–8 mA). 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.

Dose index 1 was obtained using a thimble ionization chamber and SEDENTEXCT DI phantom. a SedentexCT IQ phantom according to diagnostic tasks.
