CBCT Dose Optimisation in External Beam Radiation Therapy

Stage

Methodology Development

Role

Major Contributor — Conceptualisation and Methodology Design

Overview

This project focuses on optimising Cone-Beam CT (CBCT) protocols to balance image quality and radiation dose during daily image-guided treatments. It involves a collaborative effort with physics and treatment planning teams to ensure both accuracy and safety.

Objectives

Review and refine existing CBCT protocols

Develop dose-reduction methods while preserving image clarity

Ensure clinical feasibility and consistency across treatment sites

Potential Impact

Reduce unnecessary radiation exposure for patients

Maintain high-quality imaging for precise treatment verification

Contribute to safer, more efficient radiotherapy practices

Results

Pending — methodology design nearing completion before data collection begins.
