Brachytherapy is a form of radiation therapy that uses radioactive nuclides that are implanted through interstitial needles and intracavitary or intraluminal applicators inside or near the tumour giving a high radiation dose to the malignant volume while maintaining a low dose to surrounding healthy tissues. Typically, high dose-rate (HDR) brachytherapy is performed using Ir-192 sources. Intensity modulated brachytherapy (IMBT) is a novel technique of HDR brachytherapy delivered using rotating high-Z shields that can be dynamically controlled to direct radiation away from healthy tissues. The partially-shielded catheters remove the constraint that dose distributions must be radially symmetric about each individual applicator. The main advantage of this technique resides in the improved ability to spare the surrounding healthy tissue from radiation, reducing the severity of the complications relative to HDR brachytherapy. The aim of my project is to develop a prototype delivery system for IMBT used in combination with a Yb-169 source, and evaluate the benefits of this technique for the important tumour sites treated with brachytherapy, such as head & neck, prostate, and gynaecological cancers. IMBT has the potential to decrease normal tissue toxicity and produce highly conformal dose distributions, resulting in improved patient outcomes.
