Performance of dose calculation algorithms from three generations in lung SBRT: comparison with full Monte Carlo-based dose distributions The accuracy of dose calculation is a key challenge in stereotactic body radiotherapy (SBRT) of the lung. We have benchmarked three photon beam dose calcul... JJ...
