Dual-energy linear accelerators (also referred to as “high energy,”) can produce various photon energies. Two different definitions are used, and this is often confusing to buyers of linear accelerator systems. The following chart illustrates the equivalency:
Photon Energies using the BJR #11 Definition | 4MV | 6MV | 10MV | 15MV | 18MV | 20MV | 24MV |
Equivalent Energies using the BJR #17 Definition | 4MV | 6MV | 10MV | 16MV | 23MV | 25MV | 30MV |
*BJR is the abbreviation for “British Journal of Radiology”
