The present invention includes a method for MR imaging of a biological matter having H2O17 content by performing T1\u03c1off imaging of said H2O17 content in said biological matter. In particular, it relates to applying corrections to pattern data, such as corrections for distortions in the field of an SLM exposure stamp. A confidence image is generated consisting of the confidence values at the position of the respective pixel. The process for coating the brake pad is adaptable for use at a repair facility or auto parts supply store.
