RapidArc™ radiotherapy technology, a major advance from Varian Medical Systems, is setting new standards in treatment for our patients. By shortening treatment times by as much as 8 times faster than current dynamic treatments, patients are not uncomfortable as long and radiotherapy can be more effectively delivered to organs prone to frequent movement such as the prostate. Furthermore, RapidArc means lower dosages to healthy surrounding areas of the body including vital organs.
Instead of treating tumors from many different angles, as with conventional IMRT (Intensity Modulated Radiation Therapy), RapidArc treatment is given in one continuous arc. The shape of the treatment field and amount of dose changes to conform to the tumor volume while avoiding critical nearby body areas.
