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 ...
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.
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.
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.
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
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.
An Iranian teenager who claims she had 50 plastic surgeries to make herself look more like her idol is turning heads online. Sahar Tabar, 19, from Tehran, Iran, says she underwent dozens of ...
DBS for OCD, [32] Tourette's Syndrome, [33] and dystonia were first completed in 1999. [34] DBS for OCD received a humanitarian device exemption from the FDA in 2009. [35] In Europe, the CE Mark for DBS for OCD was active from 2009 to 2022 but not renewed thereafter due to a lack of coverage by government health agencies. [36] [37]
