Relationship between CNR and visibility of anatomical structures of cone-beam computed tomography images under different exposure parameters.

CONCLUSIONS: Although CNR decrease under a lower exposure parameter, the image quality often remained acceptable at exposure levels below the manufacture's recommended settings. It is possible to standardize subjective image quality by physical factors. Currently, it is not possible to predetermine a change point CNR value due to different CBCT machine and variation of diagnostic tasks.
