Abstract

The invention provides for a magnetic resonance imaging system (100) which comprise a magnet (104) and a magnetic field gradient generator (110, 112) for generating a gradient magnetic field within an imaging zone (108). The gradient magnetic field is aligned with a predetermined direction. The magnetic resonance imaging system further comprise a memory (134, 136) for storing machine executable instructions (150, 152, 154), a pre-calculated magnetic resonance fingerprinting dictionary (144), and pulse sequence instructions (140). The pulse sequence instructions cause the magnetic resonance imaging system to acquire the magnetic resonance data according to a magnetic resonance fingerprinting technique. The magnetic resonance fingerprinting technique encodes the magnetic resonance data as slices (125). The pre-calculated magnetic resonance fingerprinting dictionary contains a listing of calculated magnetic resonance signals in response to execution of the pulse sequence instructions for a set of predetermined substances. Execution of the machine executable instructions causes a processor (130) controlling the magnetic resonance imaging system to: acquire (300) the magnetic resonance …
