Claim:
1. A method for operating a magnetic resonance system comprising a data acquisition scanner comprising a radio-frequency (RF) radiator and a gradient system, said method comprising: from a control computer, operating said data acquisition scanner according to a pulse sequence; in said pulse sequence, generating a gradient, with said gradient system, in a gradient direction, as a spatially dependent magnetic field; while said gradient is generated, radiating a selective RF excitation pulse with said RF transmission system, said selective RF excitation pulse being configured to excite nuclear spins of a first material in a first partial region of an examination subject and not to excite nuclear spins of a second material in said first partial region, and to not excite nuclear spins of said first material in a second partial region of the examination subject and to excite nuclear spins of said second material in said second partial region; in said pulse sequence, radiating a number of refocusing pulses and acquiring raw magnetic resonance data from said first and second partial regions resulting from excitation of said nuclear spins of said first material and excitation of said nuclear spins of said second material, and spatially coding said raw magnetic resonance data along said gradient direction; and storing said raw magnetic resonance data in electronic form in a memory and making said raw magnetic resonance data stored in said memory available in said electronic form for further processing.
