WebNon-ionising imaging is used in medical physics to see the interior of the body, such as internal organs and joints. Non-ionising imaging includes ultrasound imaging, magnetic resonance imaging, and endoscopy. These methods are used in important areas of medical physics. Ultrasound imaging can reveal internal organ movement as well as blood ... Negatively charged ions are produced when a free electron collides with an atom and is subsequently trapped inside the electric potential barrier, releasing any excess energy. The process is known as electron capture ionization. Positively charged ions are produced by transferring an amount of energy to a bound electron in a collision with charged particles (e.g. ions, electrons or positrons) or with photons. The threshold …
