Abstract:
A magnetic resonance tomography apparatus comprising:a magnetic resonance data acquisition system which acquires magnetic resonance data using a plurality of operating parameters;a system control for setting said operating parameters, with a system control resolution, for said magnetic resonance data acquisition system; anda control device connected between said system control and said magnetic resonance data acquisition system for setting at least one of said operating parameters as a time-variable output quantity, with a resolution finer than said system control resolution, said control device comprising an input at which a slope value for said output quantity is present, and an output for said output quantity, and a clock adder, supplied with clock pulses, having an adder output connected to said output of said control device and an adder input connected to said input of said control device, said adder having a further adder input connected to said adder output, and said adder adding a current output quantity to a quantity dependent on said slope value at each of said clock pulses.
