  • Radiation dose and risk
  • Justification for referral
  • Equipment factors in the reduction of radiation risk to patients
  • Quality standards/assurance
  • Staff protection
  • Economic evaluation
  • CBCT uses

The guidelines makes over 50 recommendations covering

With the increasing availability of CBCT machines it is important that those using or considering using these machines are fully aware of these guidelines. The guidelines update the previous version published in 2009.
