Core tip: Treatment outcome in radiotherapy is highly dependent on the dose delivered to the tumor volume with minimal dose to the surrounding critical structures. Real-time dosimetry plays a crucial role in assessing the accuracy of dose delivered to patients undergoing radiotherapy.

This article highlights different approaches to assess real-time dosimetry in external beam radiotherapy.
