Extension providing radiobiologic dose metric using a regular expression: BED, CGE, RBE, RBE(factor = <decimal>), EQD2Gy, EQD2Gy(a/b = <decimal>).
Context of Use
This extension may be used on the following element(s):
This extension is used to capture the radiobiologic metric of effective dose, as defined by the TG-263 in section 9.2 of AAPM Task Group 263 Report on Standardizing Nomenclatures in Radiation Oncology. The following metrics are supported:
The units are assumed to be Gy.
One of the above metrics SHOULD be used. Use of other metrics will generate a warning.
