Ionising radiation primary beam
WebMagnetic Resonance Imaging (MRI) is a groundbreaking non-ionising imaging modality that revolutionised the field of diagnostic medicine. Developed in the 1970s, MRI uses a combination of powerful magnetic fields, radiofrequency pulses, and sophisticated computer algorithms to generate detailed images of the body’s internal structures.
