Real-time dose verification in radiotherapy

A novel radiation detector device for determining the dose from Intensity Modulated Radiotherapy (IMRT) in real-time developed by a team from the Universities of Bristol and Swansea with University Hospitals Bristol NHS Foundation Trust.

Uses

  • Dosimetry in Intensity Modulated Radiation Therapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT)

Benefits

  • Enables real-time monitoring of radiation dose delivered to the patient
  • Eliminates the need for costly and time-consuming pre-treatment patient-specific QA
  • Enables timely intervention if treatment deviates from plan thus reducing the risk of mistreatments during radiotherapy

Upstream dosimetry system for real-time verification of modulated radiotherapy treatments

The detector is positioned upstream of the patient (between the radiation source and the patient) and is a very thin silicon detector camera system. The detector minimises interference with the radiation beam (<1% attenuation). It can measure the beam profile and deliver the dose very quickly with high resolution and precision.
