Gantry (medical)
In a medical facility, such as a hospital or clinic, a gantry holds radiation detectors and/or a radiation source used to diagnose or treat a patient's illness. Radiation sources may produce gamma radiation, x-rays, electromagnetic radiation, or magnetic fields depending on the purpose of the device. CT scanner The gantry of a computed tomography scanner (CT) is a ring or cylinder, into which a patient is placed. The x-ray tube and x-ray detector spin rapidly in the gantry, as the patient is moved in and out of the gantry. The CT scanner produces 3-dimensional x-ray images of the patient. Nuclear magnetic resonance imaging An MRI gantry remains fixed, and contains cryogenically cooled superconducting electromagnets and radio transmitters that flip protons in hydrogen atoms in the human body via proton nuclear magnetic resonance. The machine then listens and processes the signals given off by the hydrogen atoms as the protons flip back in order to produce a 3D image of the ...
