Gradient echo signal and contrast calculator

First choose tissue T1 and T2 values.
Then select your scanning TR, TE  and flip angle. You can also set a field inhomogeneity factor. The calculator uses an estimated value of T2* based upon this and the tissue T2.
The graph shows the signal intensity (max = 1) for both tissues, the contrast and the relative contrast to noise ratio (CNR).

The calculator currently works on computers and Android devices only.
