For image evaluation of low contrast targets with CT, tomosynthesis as well as cone beam CT.
- Comparison between CT and tomosynthesis images
- Three different planes with one scan
- A variety of nodules that simulate GGO
- Quantitative evaluation of image quality, using CNR of simulated nodules
- Visual evaluation of image quality, using contrast detail diagram
- Elliptical radiation absorber that simulate human body, to study scattering effect of soft tissue
