How does gamma radiation work
WebNov 18, 2014 · Processes that CreateCosmic Gamma Rays. There are several physical processes that generate cosmic gamma rays: A high-energy particle can collide with another particle. A particle can collide and annihilate with its anti-particle. An element can undergo radioactive decay. A charged particle can be accelerated. WebThe high-energy gamma photons meet a detector called a scintillation crystal, which converts them into light. This light is then amplified and processed by the camera to reveal the distribution of the radiopharmaceutical in two dimensions. Gamma cameras are an …

Webgamma ray, electromagnetic radiation of the shortest wavelength and highest energy. Gamma rays are produced in the disintegration of radioactive atomic nuclei and in the decay of certain subatomic particles. The commonly accepted definitions of the gamma-ray and … WebThe gamma camera detects the energy from the radiotracer in your body and converts it into an image. The gamma camera itself does not emit any radiation. It has radiation detectors called gamma camera heads. These are often shaped like a box and attached to a round, donut-shaped gantry.
WebThis uses radiation beams called gamma rays. The rays are sent from a machine and focused at the tumor from hundreds of angles at the same time. Treatment is usually done in 1 session. Linear accelerator based. Instead of sending many beams at once, this machine moves around the head to send radiation to the tumor from different angles.
