The CyberKnife system is a radiation therapy device manufactured by Accuray. The system is used to deliver radiosurgery for the treatment of benign tumors , malignant tumors and other medical conditions.
The treatment field's length (the width of the radiation slice) is adjustable using collimator jaws. In static-jaw delivery, the field length remains constant during a treatment. In dynamic-jaw delivery, the field length changes so that it begins and ends at its minimum setting. Patient undergoing tomotherapy, face and body covered, to prevent ...
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.
The field of radiation therapy began to grow in the early 1900s largely due to the groundbreaking work of Nobel Prize–winning scientist Marie Curie (1867–1934), who discovered the radioactive elements polonium and radium in 1898. This began a new era in medical treatment and research. [119]

External beam radiation therapy (EBRT) is a form of radiotherapy that utilizes a high-energy collimated beam of ionizing radiation, from a source outside the body, to target and kill cancer cells. The radiotherapy beam is composed of particles, which are focussed in a particular direction of travel using collimators [ 1 ] .
The studies are titled, “Prostate CyberKnife Stereotactic Body Radiotherapy: Report on the Early Experience at a Community-based CyberKnife Center” Year 1 and Year 2. [ 6 ] In February 2012, a group of physicians from Mexico City traveled to the U.S. and were trained by the Reno CyberKnife staff to prepare for the arrival of the second ...
