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).
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).
Typical uses for this technology include detection of items for commercial loss prevention, smuggling, and screening for weapons at government buildings and airport security checkpoints. It is one of the common technologies of full body scanner used for body imaging; a competing technology is backscatter X-ray .
Cobalt therapy is the medical use of gamma rays from the radioisotope cobalt-60 to treat conditions such as cancer.Beginning in the 1950s, cobalt-60 was widely used in external beam radiotherapy (teletherapy) machines, which produced a beam of gamma rays which was directed into the patient's body to kill tumor tissue.
Image-guided radiation therapy is a method that uses imaging to correct for positional errors of each treatment session. [citation needed] The response of a tumor to radiation therapy is also related to its size. Due to complex radiobiology, very large tumors are affected less by radiation compared to smaller tumors or microscopic disease ...
Tomotherapy is a type of radiation therapy treatment machine. [1] [2] [3] In tomotherapy a thin radiation beam is modulated as it rotates around the patient, while they are moved through the bore of the machine. The name comes from the use of a strip-shaped beam, so that only one “slice” (Greek prefix “tomo-”) of the target is exposed ...
Elon Musk announced on Monday that the first human has received a brain implant through his Neuralink startup—marking a new step forward for the company and its goal to connect the human brain ...
Scintigraphy (from Latin scintilla, "spark"), also known as a gamma scan, is a diagnostic test in nuclear medicine, where radioisotopes attached to drugs that travel to a specific organ or tissue (radiopharmaceuticals) are taken internally and the emitted gamma radiation is captured by gamma cameras, which are external detectors that form two-dimensional images [1] in a process similar to the ...
