Why do patients who need focused, precise doses of radiation get walloped with huge overdoses that cause serious and even fatal injuries? A deadly combination of nonuser- friendly radiation equipment, incompatible software when machines from different manufacturers are cobbled together, user error by the technicians administering the radiation, and lax regulation by federal authorities: All these are major issues in the ongoing expose by the New York Times of malpractice issues in radiation therapy.
