What is the CyberKnife? Chapter 9 — Brain Metastases: A Documentary
Показать описание
This chapter explains what the CyberKnife system is and how it's used to treat brain metastases.
The CyberKnife is a low-dose linear accelerator that is mounted on a robotic arm. In the case of brain metastases, it treats one tumor after another by moving from location to location.

Video Transcript:
Dwight Heron, MD: The CyberKnife is a robotically mounted small linear accelerator that delivers radiation therapy at a much lower dose rate and it does it in a node-based pattern, so it moves from one location to the next location to the next location. Not in a sweeping action. That results frequently in treatment plans that are qualitatively similar, meaning that if I want to deliver 18 Gy to a small tumor, whether it’s the Gamma Knife or the Novalis system or the CyberKnife system, they can all do that. The way the dose is spread out and the way it’s delivered is really the crux of the differences, and the speed, do treatment times are the important part. Much like the Novalis system, the CyberKnife does have stereoscopic imaging that allows us to image the patient and confirm that the patient’s in the right location during the entire course of treatment.
