    en.wikipedia.org/wiki/Delayed-maturation_theory...

    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 ...

  3. Cyberknife (device) - Wikipedia

    en.wikipedia.org/wiki/Cyberknife_(device)

    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).

  4. Radiosurgery - Wikipedia

    en.wikipedia.org/wiki/Radiosurgery

    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.

  5. Stereotactic surgery - Wikipedia

    en.wikipedia.org/wiki/Stereotactic_surgery

    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.

  6. Therac-25 - Wikipedia

    en.wikipedia.org/wiki/Therac-25

    The Therac-25 is a computer-controlled radiation therapy machine produced by Atomic Energy of Canada Limited (AECL) in 1982 after the Therac-6 and Therac-20 units (the earlier units had been produced in partnership with Compagnie générale de radiologie (CGR) of France).

  7. John R. Adler - Wikipedia

    en.wikipedia.org/wiki/John_R._Adler

    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 ...

  8. Gamma irradiation - Wikipedia

    en.wikipedia.org/wiki/Gamma_irradiation

    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

  9. Vestibular schwannoma - Wikipedia

    en.wikipedia.org/wiki/Vestibular_schwannoma

    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 ...
