Core Tip

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. Several radiotherapy accidents would have been avoided if real-time dosimetry was part of the radiotherapy treatment procedure. This article highlights different approaches to assess real-time dosimetry in external beam radiotherapy.
