The inaugural CyberKnife system was installed at Stanford University in 1991, receiving clearance for clinical investigation by the U.S. Food and Drug Administration (FDA) in 1994. Following extensive clinical research, the FDA granted approval for the treatment of intracranial tumors in 1999 and for tumors throughout the body in 2001 ...
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. There is not a clear difference in efficacy between these different approaches.
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]
Cyberknife may refer to: Cyberknife (horse), a Thoroughbred race horse, winner of the 2022 Arkansas Derby; Cyberknife (device), is a radiation therapy device manufactured by Accuray Incorporated; Oklahoma CyberKnife, is a cancer treatment center based in Oklahoma; Reno CyberKnife, is a cancer treatment center based in Reno, Nevada
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 ...
Compton scattering is the dominant interaction between a megavoltage beam and the patient, while the photoelectric effect dominates at keV energies. Additionally, Compton scattering is much less dependent on atomic number than the photoelectric effect; while kilovoltage beams enhance the distinction between muscle and bone in medical imaging ...
Radiation therapy is a local treatment that is designed to treat the defined tumour and spare the surrounding normal tissue from receiving doses above specified dose tolerances. There are many factors that may contribute to differences between the planned dose distribution and the delivered dose distribution.
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.
