Featured Case Studies

Robotic Stereotactic Body Radiation Therapy For High-risk Prostate Cancer: The Georgetown University Experience
This retrospective study examines cancer control and health-related quality of life (HRQOL) outcomes in high-risk prostate cancer patients receiving robotic stereotactic body radiation therapy (SBRT) with Synchrony® real-time adaptive motion management.

Use of Motion Management to Model Unmanaged Motion: Dosimetric Consequences of Unmanaged Prostate Motion Assessed Using Real-time Radiotherapy Adaptation Data
This case report explores the dosimetric impact of unmanaged intrafraction prostate motion during radiotherapy by retrospectively analyzing real-time motion data collected using the Radixact® System with Synchrony®. The study models what would have happened if a patient had been treated without motion management, using deformation vector fields to simulate dose

Stereotactic Body Radiotherapy of a Lung Tumor with Large Respiratory Motion Using Real-time Adaptive Motion Management: A Case Report
Traditional internal target volume (ITV) methods for the treatment of a lung tumor on conventional linac would require a large planning target volume (PTV), risking high radiation exposure to the chest wall and lungs.
