Gamma knife: A gamma knife delivers a focused dose of radiation to a precise spot on the brain. A neursurgeon places a “halo” on the patient that helps guide the radiation oncologist in “aiming” the “knife.” (If there are any neurosurgeons and/or radiation oncologists reading this, please forgive this “layman’s” explanation). On Thursday, November 2, 2017, Lynette and I visited with a neurosurgeon and a radiation oncologist at MD Anderson to have the procedure explained and to give consent for the procedure. It was also explained that “gamma knife time” was in high demand. There would be a wait of at least a couple of weeks before the procedure could be scheduled. I knew that UMMC also had a gamma knife and thought it was possible we could have THAT procedure in Jackson.
