Question

Quizplus · Accepted Answer

Cobalt-60-based units are generally not used for intraoperative radiation therapy (IORT) procedures of the brain. IORT typically involves the use of electrons (electron IORT) or high-dose-rate brachytherapy sources, rather than Cobalt-60, which is more commonly associated with external beam radiotherapy.
