Dosimetric evaluation using EPR/alanine and radiochromic film detectors in end-to-end brain stereotactic radiosurgery sessions
Abstract This pilot study aimed to establish end-to-end stereotactic radiosurgery (SRS) sessions and evaluate the accuracy of the delivered doses using EPR/alanine and GAFChromic™ EBT3 films. Six Planning Treatment Volumes (PTVs), representing variations in tumor size, location, and proximity to Organs at Risk (OARs), were assessed using an anthropomorphic male head phantom irradiated with a TomoTherapy Hi-Art system (fraction of 10.5 Gy). Maximum deviations ranged from − 0.35 to 0.16 Gy, and − 0.35 to − 0.08 Gy, for alanine and films, respectively, even under complex spatial dose distribution (e.g., PTV6). Therefore, the findings demonstrated the reliability of both systems for precise SRS dosimetry.
