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 ...
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 ]
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.
Surgery of previously irradiated tissue has a very high failure rate, e.g. women who have received radiation for breast cancer develop late effect chest wall tissue fibrosis and hypovascularity, making successful reconstruction and healing difficult, if not impossible.
Comedian Bridget McGuire shares the intrusive thoughts with harm that her obsessive compulsive disorder caused, and how stand-up got her out of her own head.
The device consists of a small linear accelerator attached to a robotic arm, along with an integrated image guidance system. 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.
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.
A gamma camera (γ-camera), also called a scintillation camera or Anger camera, is a device used to image gamma radiation emitting radioisotopes, a technique known as scintigraphy. The applications of scintigraphy include early drug development and nuclear medical imaging to view and analyse images of the human body or the distribution of ...
