Real-time image-guided adaptive radiotherapy achieved on a standard linac

Real-time image-guided adaptive radiotherapy (IGART) is currently limited to expensive, dedicated cancer radiotherapy systems. The combination of two software programs that can be used with any standard linear accelerator – an image-based real-time tumour localisation system and a real-time multileaf collimator tracking system – offers the potential for widespread implementation of real-time IGART.
