Abstract
In a magnetic resonance imaging apparatus, a main magnet assembly ( ) produces a uniform magnetic field through an imaging region ( ). An imaging region is defined within a subject by selecting gradient magnetic fields spatially encode the main magnetic field. A whole body birdcage radio frequency coil ( ) excites magnetic resonance in dipoles of the subject. The resonance signals are received by the whole body coil ( ) and by a second, local birdcage radio frequency coil ( ). The first radio frequency coil ( ) produces and is sensitive to a uniform radio frequency field in the imaging region ( ) while the second radio frequency coil ( ) is sensitive to a field that varies sinusoidally in space. From one radio frequency excitation, the two birdcage coils ( ) receive different sets of data with which to fill k-space, accelerating data collection.
