Within the bore of an MRI scanner the protons are aligned to the magnetic field. The MRI machine produces repeating sequences of radiofrequency pulses to 'excite' protons in the body. As protons in the body 'relax' they … WebX-rays are produced by means of a cathode ray tube, which is similar to the tube of a television. Electrons are accelerated from a cathode at high speed towards a metal anode. As they hit the metal anode, they release energy. Over 95% of this energy is released as heat and less than 5% of the electrons' energy is converted into x-rays. f1 gp belgica 2022
