Description and Objectives:

Webinar Description:

The Winston-Lutz test has long been a key quality assurance (QA) test for verification of radiosurgery. With the rise of single-isocenter multi-met SRS, new challenges in treatment accuracy have emerged. To meet these demands, the test has been evolved to validate off-axis deliveries while remaining efficient.

This webinar will explore the complexities of off-axis target localization and verification in these treatments. Attendees will learn about advanced QA methods and practical clinical applications. The session aims to provide actionable strategies to improve the accuracy and reliability of SRS treatments.

Learning Objectives

To explore various off-axis Winston-Lutz solutions.
To Understand the practical considerations for clinical implementation of these solutions.
To evaluate machine performance enhancements in comparison to traditional off-axis Winston-Lutz tests."
