Mobile linear accelerators for intraoperative radiation therapy

Intraoperative radiation therapy (IORT) is becoming an increasingly common procedure for treating gross tumors or tumor beds after resection. Traditionally, IORT delivery required either heavily shielded ORs or transporting anesthetized patients to the department of radiation oncology. The availability of a self-shielded mobile electron linear accelerator has made this treatment modality accessible to institutions that otherwise would not consider performing IORT. This article describes IORT equipment and supplies and addresses perioperative nursing issues, as well as the roles of other team members involved in the delivery of IORT.
