This tool allows you to perform parameter mapping or curve fitting to canonical MRI signal equations. You may calculate diffusion weighted imaging (DWI), relaxometry (T1 relaxation, T2 relaxation, T2* relaxation)] parameters directly from your browser. The fitting is performed using non-linear least squares. Get started by choosing the parameters you wish to fit, and entering the data in the fields below.

Hint: The data you enter may be separated by any combination of the following delimiters: comma, space, semicolon, newline.

Hint: Advanced users can choose initial parameters for the curve fitting.
