Neurosurgeons to operate brain cancer without using scalpels

The device enables to aim radiation beams at a malignancy inside the brain
A new set of equipment will be commissioned soon at the Burdenko Neurosurgery Research Institute in Moscow. It comprises a linear accelerator and a gamma knife. Thanks to new equipment, patients will be able to leave hospital premises right after a medical procedure is over. In the past, patients had to spend weeks in hospital recovering after a complex skull trepanation.
First the doctors need to adjust a coordinate frame to a stereotaxic device on a patient's head. The device enables to aim radiation beams at a malignancy inside the brain. The linear accelerator will start moving around the patient's head once the frame is adjusted. The accelerator has a many-petaled collimator for "mapping out" the tissues to produce images of a tumor. The collimator will then direct a flux of photons to destroy the cancer cells. The procedure will be repeated at different planes until the tumor is completely irradiated. The whole procedure takes a couple of hours to complete, a patient feels no pain whatsoever while undergoing it. . .
