What is the annual enhanced dynamic or gated delivery dose tolerance?

• A. 100 MU or expected delivery
• B. 50 MU or expected delivery
• C. 5 MU or expected delivery
• D. 200 MU or expected delivery

Answer: (A)

In this area, the tolerance for dynamic or gated delivery is tied to the total amount of dose (in MU) you expect to deliver over a year. The idea is to guard against cumulative delivery drift from gating and motion-management deliveries, rather than just a per-visit check. The practical rule is that the annual tolerance is set as either a fixed 100 MU or the total MU you expect to deliver for enhanced dynamic/gated deliveries in that year, whichever reflects your actual workload. This means you’re allowed a cumulative difference of about 100 MU unless your annual planned delivery for these techniques is higher, in which case you use that expected total as the tolerance. This approach keeps the standard realistic for clinics with light use and scalable for busier practices, while still catching meaningful drift in the system over time.
