In a magnetic resonance transmission method and magnetic resonance transmission operating therewith a high-frequency power amplifier emits an output signal with an actual amplitude and an actual phase to a magnetic resonance transmission antenna. A fraction of the signal is digitilized in a magnetic resonance receiver and is supplied to a pulse controller that is realized in software. An analog magnetic resonance reception signal of an object can be supplied to the magnetic resonance receiver during the pulses. The pulse controller determines correction values for a generator amplitude and a generator phase with which a pulse generator is driven, the pulse generator being connected upstream relative to the high-frequency amplifier.

Magnetic resonance transmission method supplying fraction of output signal to receiver and using intermediate signal as scanning signal

A medical diagnostic apparatus has a computer, a bus, processors, memories and an input arrangement, the imput arrangement including an adjustment arrangement for the nearly simultaneous adjustment of at least two input parameters, to which a processor is allocated for conversion into control parameters.

Imaging system for a medical diagnostic apparatus

In a method in the form of a pulse sequence for operating a diagnostic magnetic resonance apparatus, a predecessor gradient field and a successor gradient field are generated in an examination volume. The predecessor and successor gradient fields are spatially rotated relative to one another by an angle unequal to 90.degree.. The predecessor gradient and the successor gradient field are generated partially overlapping in time.

Pulse sequence for a diagnostic magnetic resonance apparatus

In a method for operating a magnetic resonance apparatus, having a radio frequency system for transmitting radio frequency excitation pulses and/or for receiving magnetic resonance signals and a gradient system for generating temporally variable, magnetic gradient fields the excitation pulses and gradient fields are activated dependent on time-variant signals. The time-variant signals are made available in the form of discrete signal values. Each discrete signal value of at least one signal is generated by a virtual machine by processing a virtual machine program.
