The Necessity of ExacTrac for 6D Image-Guided Radiosurgery
Nzhde Agazaryan, Chief of Clinical Medical Physics at the University of California Los Angeles Medical School discusses the necessity of ExacTrac for 6D image-guided radiosurgery. He begins with an overview of ExacTrac and how the technology functions as a positioning and monitoring system for radiosurgery. He then goes in to how to apply ExacTrac in a clinical practice by giving case examples of planning and delivery for the treatment of trigeminal neuralgia, spine tumors, multiple brain metastases, acoustic neuroma, arteriovenous malformations and meningioma.
