The inventors were very excited and drove the first patient from Stockholm over 100 km for the first treatment. The treatment was a technical success. The new machine was transported to Sophiahemmet (a private Stockholm hospital) and installed. A further eight patients were treated and assessed.

The term Gamma Knife was first used later by the Pittsburgh group.
