IGRT: Image-matching workshop in MV or kV (RTT)

1. Overview

This workshop is designed to equip radiation therapists with the practical skills and conceptual tools necessary to perform fast and efficient Megavoltage (MV) and Kilovoltage (KV) image matching for Image-Guided Radiation Therapy (IGRT). It provides essential strategies for troubleshooting, repositioning, and avoiding common errors across various complex anatomical sites, ensuring the highest level of treatment accuracy.

2. Key Learning Objectives

After this course, you will be able to:

• Perform Megavoltage (MV) and Kilovoltage (KV) image matches quickly and efficiently.

• Apply the "Pre-Imaging Chain" of basic checks to avoid setup problems and improve image quality.

• Read situations that require immediate patient repositioning or technical troubleshooting to maintain treatment accuracy.

• Identify potential collisions and use strategies like patient offsetting to manage machine and couch movement.

• Utilize imaging techniques, filters, and window leveling to maximize anatomical visibility for complex matches.

• Analyze and address common errors and mistakes associated with Image-Guided Radiation Therapy (IGRT) setups.

• Establish correct patient alignment for challenging sites, including the spine, abdomen, and extremities.
  
  

3. Why You Should Attend (The Benefits)

• Develop conceptual tools and practical skills to significantly enhance the speed and quality of your daily image matches.

• Learn proactive strategies to filter out potential planning or setup mistakes, saving valuable treatment time and reducing patient anxiety.

• Boost your confidence in handling complex IGRT setups by understanding best practices for troubleshooting and safe machine operation.

• Ensure the delivery of the safest and most accurate radiation treatment by mastering proper image verification.
