Radiosurgery is surgery using radiation, [1] that is, the destruction of precisely selected areas of tissue using ionizing radiation rather than excision with a blade. Like other forms of radiation therapy (also called radiotherapy), it is usually used to treat cancer.
To assure quality of patient care the procedure involves a multidisciplinary team consisting of a radiation oncologist, medical physicist, and radiation therapist. [9] [10] Dedicated, commercially available stereotactic radiosurgery programs are provided by the irrespective Gamma Knife, [11] CyberKnife, [12] and Novalis Radiosurgery [13 ...
Stereotactic treatments can be confusing because many hospitals call the treatments by the name of the manufacturer rather than calling it SRS or SBRT. Brand names for these treatments include Axesse, Cyberknife, Gamma Knife, Novalis, Primatom, Synergy, X-Knife, TomoTherapy, Trilogy and Truebeam. [75]
Gamma knife surgery is a form of radiotherapy, more specifically radiosurgery that uses beams of gamma rays to deliver a certain dosage of radiation to the tumor. Gamma knife surgery is incredibly effective at treating neurocytoma and maintaining tumor control after the procedure when a complete excision has been performed.
The facility is based in the Balestier Road-based ParkwayHealth Day Surgery & Medical Centre. [3] An independent medical centre, any member of the public, local or foreigner, is entitled to make use of it. [5] The centre promotes itself as "Asia's leading gamma knife centre" and "the only gamma knife facility in Singapore". [3]
In the procedure called gamma-knife surgery, multiple concentrated beams of gamma rays are directed to the growth in order to kill the cancerous cells. The beams are aimed from different angles to concentrate the radiation on the growth while minimizing damage to surrounding tissues.
Neurosurgery products, such as the Leksell Stereotactic System, [10] an arc-based stereotactic frame, based on a polar coordinate system, that is fixed to the patient's head when performing minimally invasive stereotactic neurosurgery procedures. Leksell Gamma Knife, used to treat brain tumors by administering high intensity gamma radiation ...
The device consists of a small linear accelerator attached to a robotic arm, along with an integrated image guidance system. During treatment, the image guidance system captures 3D images, tracks the movement of tumors, and guides the robotic arm to accurately aim the treatment beam at the moving tumor.
