Physics of MRI. Physics of MRI - Detailed. Magnetism is a property of matter that is a result of the orbiting electrons in atoms. The orbiting electrons cause the atoms to have a magnetic moment associated with an intrinsic angular momentum called spin. Spin will be discussed in more detail a little bit further down hensive overview of the field, as the subject of magnetic resonance imaging (MRI) physics is large and complex.

Magnetic resonance imaging (MRI) basic physics can be described at many different levels, ranging from purely descriptive all the way to quantum mechanics. Here, MRI physics is dealt with mostly in a descriptive manner, and simple mathematics are introduced only if necessary. The simple vector-based model for representing the magnetization is. In MRI, contrast in the image is obtained through three mechanism i.e. T1 recovery, T2 decay and proton density. The image contrast depends on how much we allow each process to happen.
