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.

Scanning :

 
  Prior to treatment with the CyberKnife System, the patient undergoes imaging procedures to determine the size, shape and location of the tumor. The process begins with a standard high-resolution CT scan, or for certain tumors other imaging techniques, such as MRI, angiography or PET, may also be used.    
       
 

Planning :

   
 
Following the scanning, the image data is then digitally transferred to the CyberKnife System's treatment planning workstation, where the treating physician identifies the exact size, shape and location of the tumor. A qualified physicist then uses the CyberKnife software to generate a treatment plan to provide the desired radiation dose to the identified tumor location while avoiding damage to the surrounding healthy tissue. The patient does not need to be present during this step in the process.
 
 

 

   
 

Treatment :

   
  During a CyberKnife procedure, a patient lies comfortably on the treatment table, which automatically positions the patient. Anesthesia is not required, as the procedure is painless and non-invasive. 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 .  
       
  Follow-up :    
  Follow-up imaging, generally performed with a combination of CT, MRI and/or PET scanning, is usually performed in the months following treatment to assess the tumor's response to the delivered radiation.
