Conclusion:

This in silico study demonstrates that regularization of breathing with mechanical ventilation at 60 brpm with PEEP results in reduced target volumes and reduced heart and lung dose burden, potentially reducing radiation-associated toxicity in the treatment of esophageal cancer.

Keywords: Regularized breathing, esophageal cancer
