The LIGHT program (Linac for Image-Guided Hadron Therapy) hopes to create a design capable of accelerating protons to 200MeV or so for medical use over a distance of a few tens of metres, by optimising and nesting existing accelerator techniques [28] The current design (2020) uses the highest practical bunch frequency (currently ~ 3 GHz) for a ...
1977/1978 - Raymond Damadian built the first MRI scanner and achieved the first MRI scan of a healthy human body (1977) with the intent of diagnosing cancer. [4] Additionally, Peter Mansfield develops the echo-planar technique, producing images in seconds and becoming the basis for fast MRIs. [5] 1983 - Introduction of the k-space by D B Twieg [6]
Other radiation therapy machines which incorporate real-time MRI tracking of tumors are currently in development. MRI-guided radiation therapy enables clinicians to see a patient's internal anatomy in real-time using continual soft-tissue imaging and allows them to keep the radiation beams on target when the tumour moves during treatment.

Linear accelerator Animation of the operation of a medical use linear accelerator. The French company CGR manufactured the Neptune and Sagittaire linear accelerators.. In the early 1970s, CGR and the Canadian public company Atomic Energy of Canada Limited (AECL) collaborated on the construction of linear accelerators controlled by a DEC PDP-11 minicomputer: the Therac-6, which produced X-rays ...
Gantry of an MRI scanner. 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 ...
