Dr Siobhra O’Sullivan Talks New Cancer Treatment Technology with Pat Kenny on Newstalk

Dr Siobhra O’Sullivan, Consultation Radiation Oncologist, recently spoke to Newstalk‘s Pat Kenny about the new RapidARC Dynamic (RAD) cancer treatment.

Beacon Hospital is delighted to be the first in Ireland and the UK (and only the 5th in Europe!) to use this incredible new technology with our Varian Truebeam to treat cancer.

RAD has a number of advantages over current radiotherapy treatments. It allows for more complex computer modelling of the radiation dose distribution to the tumour, reducing the dose to surrounding healthy tissue and giving the ability to increase the dose to the tumour.

Combined with the HyperSight technology on the Varian Truebeam, there is more precise treatment delivery to the tumour.

Well done to Dr O’Sullivan and all in the incredible Radiation Oncology team here at Beacon Hospital!
