Abstract
An imaging system includes determination of a first range of values of an imaging parameter, determination of a cost function expressing a difference between a first pulse profile and a second pulse profile, the second pulse profile generated based on respective values of each of a set of pulse parameters, identification of first coefficient values of each function of a set of functions which substantially minimize the cost function over the first range of values of the imaging parameter, where each of the set of functions determines a value of a respective one of the set of pulse parameters based on a value of the imaging parameter, and storage of the first coefficient values of each function of the set of functions in association with the first range of values.
