T2 relaxation is the process by which the transverse components of magnetization (M xy) decay or dephase. As originally described by Felix Bloch (1946), T2 relaxation is considered to follow …

In physics, the spin–spin relaxation is the mechanism by which Mxy, the transverse component of the magnetization vector, exponentially decays towards its equilibrium value in nuclear …

The decay of RF-induced NMR spin polarization is characterized in terms of two separate processes, each with their own time constants. One process, called T1, is responsible for the …

The general time-dependent solution for the transverse component, Equations B3.1.22 and B3.1.23, is seen to have sinusoidal terms modified by a decay factor. The sinusoidal term …

Certain MR sequences using gradient echoes and relatively long TE values are called T2*-weighted. They are used to accentuate local magnetic homogeneity effects to aid in the …

Apr 2, 2020 · T2* decay refers to an exponential decrease in M xy (i.e. signal strength) following the initial excitation pulse as a function of time constant T2*. A picture of the signal or free …

Jan 23, 2023 · Relaxation Magnetization returns exponentially to equilibrium: Longitudinal recovery time constant is T1 Transverse decay time constant is T2 Relaxation and precession …

Mar 21, 2024 · The Spin-Spin Relaxation Equation The T2 relaxation equation describes how the transverse magnetization (M xy) of a sample decays over time. The general form of this …

Jun 29, 2020 · The process by which the magnetization in the xy plane decays away, over time, to its equilibrium value of zero, is known as T2 relaxation, transversal relaxation, relaxation on …

Sep 11, 2023 · The solution to Eq. 2 is given in Eq. 3, where Mxy (t) depends on the initial transverse magnetisation Mxy (0), a time delay t and the time constant T2 which represents …
