Magnetic resonance tomography (MRT) imaging, employing RF receive coils with temporal sensitivity profile modulation

A magnetic resonance imaging (MRI) device, comprising:

• a magnetic resonance scanner being configured for accommodating an object to be imaged, including a static magnetic field device being configured for creating a static magnetic field, at least one RF transmit coil being configured for creating RF pulses, at least two RF receive coils, each having a self-resonance frequency and a spatially restricted sensitivity profile and being configured for acquiring magnetic resonance signals, and a gradient device being configured for creating magnetic field gradients;
• a control device being configured for controlling the magnetic resonance scanner;
• and
• a reconstruction device being configured for reconstructing an object image based on the acquired magnetic resonance signals, wherein:
• the magnetic resonance scanner includes at least one modulation device, which is further adapted for subjecting the sensitivity profile of at least one of the RF receive coils to a temporal profile modulation during the step of acquiring the magnetic resonance signals, wherein the sensitivity profile of the at least one of the RF receive coils is temporally changed relative to the at least one of the RF receive coils as a function of time and the self-resonance frequency is set within a predetermined receive bandwidth of a constant resonance frequency value;
• and
• the reconstruction device is configured for reconstructing the object image by utilizing the temporal profile modulation for obtaining spatial image information from the spatially encoded magnetic resonance signals.
