Evaluation of the Anatomy option using two phantoms as patient surrogates. A plan is calculated on a phantom and a verification plan is done on the Delta⁴ phantom. The plan is irradiated on the Delta⁴ phantom and on the patient surrogate phantom with a GAFCHROMIC film inserted. From the Delta⁴ measurements, the dose is back‐projected to the patient anatomy. The different calculated and measured dose distributions are compared (indicated with yellow arrows in the figure).
