What It Is

EPIgray is a dosimetry system that uses electronic portal imaging to calculate the dose delivered to a point of interest during radiation therapy. It is intended for use in verifying dose delivery accuracy in treatments such as VMAT.

Clinical Applications

EPIgray is commonly used in clinical scenarios involving radiation therapy, such as head and neck cancer treatments and 3D conformal radiotherapy for breast cancer. It helps ensure accurate dose delivery by comparing planned and delivered doses.

Evidence Summary

The available literature includes nine studies, comprising various study types such as RCTs and retrospective analyses, conducted between 2021 and 2025. These studies focus on the effectiveness and optimization of EPIgray in different clinical settings.

Reported Outcomes

Published studies report that EPIgray effectively monitors dose delivery in head and neck VMAT treatments, with evidence supporting its use in optimizing 3DCRT for breast cancer. The system helps identify dose tolerance failures and improve treatment accuracy.

Safety Profile

Reported complications include potential inaccuracies due to patient positioning shifts, which can affect dose calculations. However, no significant adverse events have been documented in the reviewed studies.

Evidence Limitations

The evidence is limited by the small number of studies and the need for more large-scale, randomized trials. Further research is needed to explore long-term outcomes and optimize the system for various treatment modalities.
