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.
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 ...
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 ...
Accuray's (ARAY) CyberKnife S7 System gets selected by the CARTI medical care team, thereby offering better cancer care in Arkansas via expanded access to advanced technology.
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]
It is the developer of innovative technologies, the CyberKnife and TomoTherapy platforms, including the Radixact System, the latest generation TomoTherapy platform. [2] The company is headquartered in Sunnyvale, CA, the United States. [3] The platforms are installed in leading healthcare centres in approximately 50 countries globally.
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.
This technology allows radiotherapy treatment planners great flexibility in shielding organs-at-risk (OARSs), while ensuring that the prescribed dose is delivered to the target organs. A typical multi-leaf collimator consists of two sets of 40 to 160 leaves, each around 5–10 mm thick and several centimetres long in the other two dimensions.
