The gamma knife directs more than 200 thin beams of gamma radiation at different angles toward a single point in a person's brain. While each beam delivers a trivial amount of radiation, the spot where they converge receives enough energy to destroy that tissue, making the gamma knife a precision tool for attacking small tumors , malformed ...
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. [2] The system is designed for stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT).
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.
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.
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
Leeds Gamma Knife Centre is based in the Institute of Oncology at St James's University Hospital in Leeds, West Yorkshire, England. St. James's Institute of Oncology (Bexley Wing), a National Health Service (NHS) hospital, is the largest cancer research hospital in Europe. [ 1 ]
The first Gamma Knife machine was operable in Sweden in 1969, and the first Gamma Knife in the U.S. was installed in 1987 at the Presbyterian University Hospital in Pittsburgh, PA. Departments of radiation oncology at major medical centers began to modify X-ray linear accelerators (linacs) to do single-session radiosurgery and multiple-session ...
Image guided surgery systems use cameras, ultrasonic, electromagnetic or a combination of fields to capture and relay the patient's anatomy and the surgeon's precise movements in relation to the patient, to computer monitors in the operating room or to augmented reality headsets (augmented reality surgical navigation technology).
