The patients requiring Gamma Knife radiosurgery will usually be suffering from a dangerous, potentially life threatening and thus intensely worrying condition. Yet where are they to receive information of the treatment, if their own doctor decides that this is the best option? There is a certain ...

Newer models of the Gamma Knife allow for intensity modulation, which can produce more conformal dose distributions. For radiosurgery, the Leksell frame is attached to the patient, and then a planning CT scan is performed and is uploaded to the treatment planning software. Once a plan is ...
