Time Constant Tool: y = exp(-x/400)
By introducing a minus sign, the exponential curve becomes a decay curve.
Navigate below to the next equation in the list: 1 - exp (-x/400).
Remember, T1, T2 and T2* are time constants.
An understanding of time constants allows easier understanding of MRI signal equations. This tool allows you to build up the equations describing the change of magnetisation in basic pulse sequences.
