IGRT in contemporary radiotherapy
Image-guided radiotherapy (IGRT) tools and protocols have changed considerably in recent years, with increasing use of volumetric and online IGRT techniques. This event will provide radiotherapy professionals with the information they need to understand best practice in the application of clinical IGRT. Image-guidance protocols for common clinical sites will be discussed and the evolving role of adaptive radiotherapy techniques described.
Where daily online IGRT is in use, the accepted methodology for margin calculation can be difficult to apply. We will present the new report from the BIR into this topic, and discuss how residual errors such as delineation error, deformation error, rotational variation, matching error amongst others can be measured and incorporated into a CTV-PTV margin formula.
