Understanding CyberKnife And Gamma Knife Procedures
Before deciding on a treatment, it’s important to understand the differences in procedures between CyberKnife and Gamma Knife.
The Gamma Knife procedure requires a head frame to be bolted into the skull, providing stability for treatment. On the other hand, CyberKnife treatments are non-invasive and use a soft mesh mask for patient positioning, ensuring comfort throughout the procedure.
Another key difference is the timing of the imaging, treatment plans, and actual treatment. With the Gamma Knife, all of these steps typically occur on the same day, allowing for immediate action. In contrast, CyberKnife treatments offer more flexibility, as imaging and scans can be completed days before the treatment. This means that patients can have a better understanding of their condition and have a more organized treatment plan.
CyberKnife treatments can be completed over the course of two to five days, delivering smaller doses of radiation with extreme accuracy. This approach minimizes side effects compared to the Gamma Knife’s single high-dose treatment. Patients often appreciate the convenience of a shorter treatment timeline and the reduced likelihood of experiencing adverse effects.
By understanding the procedures of both CyberKnife and Gamma Knife, patients can make informed decisions about which treatment option is best suited for their specific needs.
