Elekta’s Leksell Gamma Knife® Icon™, has been installed at our sister centre, the Queen Square Radiosurgery Centre located at the National Hospital for Neurosurgery and Neurology, part of the University College London Hospitals NHS Foundation Trust (“UCLH”).
Leksell Gamma Knife is the leading SRS system designed specifically to target brain tissue offering proven accuracy in both the location and radiation dose delivered to targeted brain tissue. Icon is the sixth generation of the Leksell Gamma Knife system, resulting from Elekta’s extensive history in SRS technology and decades of collaboration with neurosurgeons and radiation oncologists around the world.
Although it sounds like surgery, Gamma Knife radiosurgery is minimally invasive, does not involve any incisions and does not require a hospital stay. In contrast to traditional whole brain radiation therapy that exposes the entire brain to low doses of radiation over multiple sessions, Gamma Knife radiosurgery uses multiple beams of radiation at the same time to treat just the targeted area. This allows for higher doses of radiation to be delivered each treatment and as a result, patients require fewer treatment sessions. Furthermore, healthy surrounding tissues receive less radiation, resulting in fewer of the unpleasant side effects often associated with radiation therapy and improved clinical outcomes.
Since it is an outpatient procedure, Gamma Knife radiosurgery does not require a hospital stay and offers significant benefits to patients. Similarly, thanks to its minimally invasive nature, Gamma Knife also eliminates the risks associated with general surgery, and most patients are able to return to normal activities within a day, rather than weeks or even months.
Icon provides the flexibility for single dose administration or multiple treatment sessions over time. Clinicals still have the option of delivering a single large dose, as with the Gamma Knife Perfexion, as available at Thornbury and Sheffield Teaching Hospitals NHS Foundation Trust, or smaller doses in multiple sessions in what is referred to as fractionated radiosurgery. This widens the range of indications that can be treated to include larger malignant tumours. Further information can be found here.
