NEW DEVELOPMENTS IN IMAGE GUIDANCE FOR RADIOTHERAPY

Abstract

Image Guided Radiation Therapy refers to the concept of visualising the target or an important critical structure during radiotherapy to ensure accurate and reproducible radiation delivery throughout the course of treatment. There are many different methods for Image Guided Radiation Therapy, ranging from ultrasound to electronic portal imaging and volumetric CT scanning. In many circumstances, Image Guided Radiation Therapy can be enhanced by the use of implanted fiducial markers that are clearly visible and can make decision-making quicker and more robust. The most common application for image guidance at present is the accurate positioning of the target prior to treatment delivery. Howeve..
