What are RF amplifiers used for in the medical field?

Are they primarily used for MRIs, and if so, what is its function within an MRI?

Answer:
RF amplifiers are used for many things. While an MRI uses RF amplifiers to stimulate and detect the NMR signature of molecules (Reference 1), there are many other uses. For example, pacemakers today frequently have an RF interface for performance montoring and maintenance functions. High power RF transmitters are used to ablate tissue for cardiac rhythm, sleep apnea treatments, and other conditions (see Reference 2). Wireless patient montoring methods are just coming online (Reference 3).
Yes RF amplifiers are involved in MRI systems. They detect the radiation given off when the hydrogen atoms in the person change energy levels. I believe that they are also used to generate the disturbance that the atoms react to as well, but this is not my field.
