What is the requirement for stereotactic interlocks in SRS/SBRT?

Explanation:
Interlocks in SRS/SBRT must be functional. These safety devices prevent beam delivery if something isn’t right—door status, couch/gantry position, patient positioning checks, or imaging alignment—and in high-precision, high-dose-per-fraction treatments, it’s crucial that this safety chain operates reliably. Regular functional checks verify that the interlocks will halt beam-on if any abnormal condition occurs, protecting the patient from unintended exposure. Nonfunctional interlocks would compromise safety, and there’s no requirement that they be conditional on dose rate.
