What you'll learn

✓ Understand the workflow of automated radiotherapy treatment planning systems
✓ Review and approve CT imaging and contour data for radiation planning
✓ Interpret automatically generated treatment plans for quality assurance
✓ Recognize how automation streamlines multi-specialist radiation oncology workflows

Protocol

Biopharma Insights Radiation therapy is a highly complex cancer treatment that requires multiple specialists to create a treatment plan and provide quality assurance (QA) prior to delivery to a patient. This protocol describes the use of a fully automated system, the Radiation Planning Assistant (RPA), to create high-quality radiation treatment plans.

Difficulty

intermediate

Total time

~1–2 hours per patient treatment plan (depending on complexity and review iterations)

Steps

Order and approve CT imaging for treatment planning

Submit radiotherapy plan orders and review diagnostic CT images to confirm image quality and patient positioning are suitable for automated planning.

▶ 01:12

Review and approve organ/tumor contours

Examine automatically or manually generated anatomical contours (target volumes and organs-at-risk) and approve them for use in dose calculation and optimization.

▶ 03:39

Evaluate automatically generated radiation treatment plans

Assess the RPA-generated dose distributions, dose conformality, and plan quality metrics to confirm compliance with clinical objectives before plan approval.
