Organ at risk dose constraints

WitrynaOrgan at risk (OAR) dose constraints are a critical aspect of SABR treatment planning. There is limited evidence supporting preferred dose constraints for many … WitrynaFor each organ, the volumes receiving more dose than the prescribed constraints were determined. The total dose given to an organ at risk with external beam radiation in the overlapping treatment volume was calculated in EQD2 (e.g.: 50 Gy in 2 Gy/fraction is 50 Gy EQD2). This dose was subtracted from the maximum dose allowed by the …
