The Leksell Gamma Knife is a ground-breaking piece of equipment used to treat brain tumours and certain brain conditions. It directs radiation beams to a specific point in the brain without the need to cut into the skin. Because it's non-invasive and so exact, it can treat tumours that were previously considered inoperable such as those near the brain stem and cranial nerve.

Unlike conventional radiation therapy, its precision means that healthy brain tissue shouldn't be affected by the radiation. It's accurate to within 0.5mm and one treatment is usually enough. This can reduce the overall dose of unwanted radiation by up to 100 times compared to other treatments. As the side effects are minimal, people who've had Gamma Knife treatment can often go home the next day.

Our facilities

We're constantly investing in new technology at all our facilities so we can give you the best possible care. The London Gamma Knife Centre at St Bartholomew's is just one example.

GammaKnife is not an operation – there are no incisions, there’s nothing to recover from particularly after the treatment. People are usually treated as day cases whereas if I were to operate, they’d perhaps be in hospital for seven – ten days.
