摘要：

To evaluate the effects of overlapping dose volumes for varying field arrangements in PRESAGE (R), several sequential beam irradiations were delivered each to formulations intended for, and irradiated with, proton beams as well as photon beams. The dosimeters were irradiated within timespans consistent of overlapping fields in clinical treatment plans. Dose profiles taken along the beam direction indicated slight over-responses in higher dose regions relative to similar irradiations given in a single fraction. These results will aid future measurements of overlapping field treatment plans delivered to PRESAGE (R) for treatment verification of proton and photon 3D dosimetry.
