Cyberknife Radiosurgery
Treatment Process
Treatment consists of imaging with a CT scan. The CT scan is then imported into the Cyberknife Treatment Planning System. The neurosurgeon or otolaryngologist then team up with the radiation oncologist and radiation physicist to create a plan which will appropriately treat the tumor while avoiding surrounding important sensitive structures. This process is done over several days’ time so that appropriate input can be garnered from all involved, and so that an extensive quality assurance program can be completed prior to treatment.
When it is time for the patient to be treated, they are brought into the treatment room. A mask which was made at the time of the initial CT was placed, which increases accuracy, while keeping the patient in a stable, but comfortable position. Treatment is generally completed within 1-1 ½ hours. The treatment is painless and generally does not require sedation or analgesia.
