Practical radiation dosimetry across a variety of CBCT devices in Radiology.

•Comparison of dosimetry techniques across a range of CBCT systems in Radiology.•Practical issues in implementing IAEA, EFOMP and conventional techniques are described.•Adoption the EFOMP protocol for open systems (C-arms) is recommended.•Measurements using conventional CTDI techniques on enclosed systems (O-arm and Extremity CT) are recommended.
