1. Overview


This course provides a comprehensive guide to motion management in radiation therapy, detailing its fundamental challenges and mitigation strategies. It explores the critical need for reproducible patient positioning and explains various techniques like immobilization, respiratory gating, and surface-guided radiation therapy (SGRT) to ensure precise dose delivery and optimal target coverage.


2. Key Learning Objectives


After this course, you will be able to:

  • Define and differentiate between interfraction (day-to-day) and intrafraction (during treatment) patient motion.

  • Explain the detrimental effects of patient motion, including compromised Target Coverage (PTV) and increased dose to Organs at Risk (OARs).

  • Apply various patient coaching and immobilization techniques to enhance positional accuracy and reproducibility for areas like the head, thorax, and pelvis.

  • Utilize Image-Guided Radiation Therapy (IGRT), including 2D and 3D (CBCT) imaging, to monitor and adjust for patient motion.

  • Implement and troubleshoot advanced respiratory motion techniques like Deep Inspiration Breath Hold (DIBH), Phase Gating, and Amplitude Gating.

  • Describe the principles and clinical application of Surface-Guided Radiation Therapy (SGRT) for real-time body surface tracking.


3. Why You Should Attend (The Benefits)


  • Enhance your ability to deliver radiation treatment with high precision, minimizing geographical miss.

  • Gain expertise in advanced motion management technologies, improving patient safety and treatment quality.

  • Deepen your understanding of how patient motion impacts tumor volume (GTV, CTV, PTV) delineation and margin management.

  • Learn effective communication and coaching strategies to manage patient compliance and reduce motion-related errors.


4. Topics Discussed


  • Introduction to Motion Management in Radiation Therapy

  • Impact of Patient Motion on Treatment Dose, Target Coverage, and OARs

  • Understanding Gross Tumor Volume (GTV), Clinical Tumor Volume (CTV), Internal Tumor Volume (ITV), and Planning Tumor Volume (PTV)

  • Interfraction Motion (Day-to-day variations) and mitigation via coaching, immobilization, and IGRT (2D/3D)

  • Intrafraction Motion (During treatment) and management for the head, neck, and torso

  • Respiratory Motion Management: Free Breathing, Deep Inspiration Breath Hold (DIBH), and Gating

  • Simulation Procedures (4DCT) and Patient Screening for Respiratory Techniques

  • Phase Gating versus Amplitude Gating for Respiratory Motion

  • Application of Surface-Guided Radiation Therapy (SGRT) for real-time tracking
