CBCT images of a real skull phantom and a SedentexCT IQ phantom were acquired under different exposure conditions (one Dinnova3 CBCT scanner, 60- 110
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 IQ cylindrical phantom (Leeds Test Objects Ltd, Boroughbridge, UK), a dedicated dental CBCT image quality phantom, was used. 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].
Refine search result. 1 - 1 of 1 Cite Export Link to result list The SedentexCT IQ phantom was used to investigate the relationship between contrast-to-noise ratio (CNR) and dose-area product. Subjective image quality assessment was achieved using a small adult skull phantom for the same range of exposure settings.
