Today, both Gamma Knife and Linac radiosurgery programs are commercially available worldwide. While the Gamma Knife is dedicated to radiosurgery, many Linacs are built for conventional fractionated radiotherapy and require additional technology and expertise to become dedicated radiosurgery tools.
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]
Stereotactic surgery is a minimally invasive form of surgical intervention that makes use of a three-dimensional coordinate system to locate small targets inside the body and to perform on them some action such as ablation, biopsy, lesion, injection, stimulation, implantation, radiosurgery (SRS), etc.
The Gamma Knife relied on a stereotactic frame screwed into the patient's skull as an external surrogate to triangulate the location of the subject's tumor; Adler instead wanted to rely on recent medical imaging advancements and internal anatomical structures to guide the beam. Dr. Adler also sought to eliminate the costs to secure and ...
Gamma irradiation is exposure to ionizing radiation with gamma rays. It may also refer to the following processes in particular: Ionizing radiation sterilization; Food irradiation; Gamma knife, used in radiosurgery
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.
Radiosurgical methods such as Gamma knife, Cyberknife and Novalis Radiosurgery are used as well. [43] Endovascular neurosurgery utilize endovascular image guided procedures for the treatment of aneurysms, AVMs, carotid stenosis, strokes, and spinal malformations, and vasospasms.
