Before signing off a plan, what key verifications should you perform in Radiant?

• A. Confirm patient identity
• B. Confirm patient identity, confirm the correct course and prescription, verify imaging alignment, and ensure plan status is ready for verification.
• C. Verify imaging alignment only
• D. Ensure the plan has a valid signature but skip identity checks

Answer: (B)

Before signing off a plan, you perform a comprehensive readiness check that confirms you’re treating the correct patient with the intended course and prescription, that the imaging setup aligns with the plan’s geometry, and that the plan is in a ready-for-verification state. Each part plays a critical safety role: confirming patient identity prevents wrong-patient treatment; confirming the correct course and prescription ensures the plan reflects the physician’s intent and the prescribed dose and fractions; verifying imaging alignment ensures the anatomy and target are positioned as planned during treatment, reducing the chance of a geographic miss; and ensuring plan status is ready for verification confirms there are no outstanding changes or blockers and that the plan can proceed to verification. Together, these checks minimize errors and ensure the plan is truly ready for treatment.
