title: Single-beam radiotherapy knife. A practical theoretical model.
abstract: A feasibility study reveals that a standard linear accelerator, with only slight modification, can function in a manner similar to Leksell's multiple cobalt radiation device. A high radiation dose can be delivered to a 1-cm or 0.5-cm volume target with insignificant radiation effect on the surrounding tissue.
