To solve logistic problems in the method of transporting the anesthetized patient from the surgical theater to the radiation department, a new linear accelerator, named Novac7, was developed in order to enable its use in the operating room.In this paper some interesting features concerning the practice of a Novac7 unit, in the conventional way of irradiation, are presented: (1) preliminary study of medical and nursing staff radioprotection is evaluated; (2) measurements of beam intensity reproducibility have been performed; (3) isodose distributions, carried out by a radiation field analyzer using diodes and water phantom, and beam dosimetry carried out by gafchromic MD55 films in acrylic phantom to solve problems due to the high-dose-rate output of the machine are described.
Materials and MethodsNovac7 is a new compact medical linear accelerator, produced by Hitesys SpA. The accelerator is designed to produce an electron beam of 9 MeV maximum nominal energy, with a maximum beam current of 3 mA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
