Free induction decay adalah
WebT2 *-weighted imaging is built from the basic physics of magnetic resonance imaging where there is spin–spin relaxation, that is, the transverse component of the magnetization vector exponentially decays towards its equilibrium value. It is characterized by the spin–spin relaxation time, known as T2. In an idealized system, all nuclei in a ... http://mriquestions.com/what-is-t2.html
