cyber knife procedure?

My mil has brain and bone cancer, her mother keeps everyone updated on fb. She just said she has to undergo more radiation and something called a cyber knife for a spot in her brain. My husband never checks fb so I relay the updates to him and I'm sure he's going to ask what it is. Anyone know and can explain?

What is the Treatment Process?


CyberKnife® treatments involve a team approach in which several specialists participate.

Prior to the procedure, the patient is imaged using a high-resolution CT scan, to determine the size, shape and location of the tumor.

Following scanning, the image data is digitally transferred to the CyberKnife System’s workstation, where the treatment planning begins.

A qualified clinician then uses the CyberKnife software to generate a treatment plan. The plan is used to match the desired radiation dose to the identified tumor location while limiting radiation exposure to the surrounding healthy tissue.

Once the treatment plan has been developed, the patient is ready to undergo the CyberKnife procedure. After arriving at the CyberKnife Center, patients are comfortably positioned on the treatment table. Then the CyberKnife System’s computer-controlled robot will slowly move around the patient to the various locations from which it will deliver radiation to the tumor.

Each treatment session will last between 30 and 90 minutes, depending on the type of tumor being treated. If treatment is being delivered in stages, patients will need to return for additional treatments over several days (typically no more than five), as determined by the patients doctor. Patients may experience some minimal side effects, but those often go away within the first week or two after treatment.

Thank you. He will be happy to hear its not actually cutting/surgical.
