Intensity Modulated Radiation Therapy for Breast Cancer IMRT came on the scene in radiation therapy about a decade ago, and instead of just treating a target with one or two or maybe up to four beams was the old technology, it uses thousands and thousands of very, very precise little beams and each of those beam’s intensity can be small, medium, large, off or fully on and that allows you to really shape the dose of radiation to a very, very high degree, and ten years ago when it first came out the delivery systems were rather slow. So patients would often be on the table to get their intensity-modulated radiation therapy or IMRT for 20 minutes, sometimes even 30 minutes when we first started. Trilogy with RapidArc allows us to do it, well, probably in less than two minutes. The machinery, the software, and the hardware are all so integrated that treatment times have come down dramatically and as I said it before, the shorter the treatment time the less chance there is that normal tissue will be radiated that you don’t want to be radiated.
