Abstract :
Geometric uncertainties in radiotherapy result in the use of margins as a means to guarantee target coverage and normal tissue avoidance. The advantages of reducing these uncertainties are significant. Here, the authors report on the application of a new imaging technology to image-guidance in external beam radiotherapy and brachytherapy. Results are summarized
