<p>MR imaging method which is notably suitable for applications where an as short as possible acquisition time is desired. The method is based on the SENSE method which enables the image acquisition to be performed with a reduced FOV (field of view); parallel, multi-channel detection is then performed by means of receiving elements having different spatial sensitivity profiles. The method is based on the recognition of the fact that conventional birdcage resonators can be tuned to different resonance modes whose spatial sensitivity profiles deviate strongly. A birdcage resonator that is composed of a plurality of sub-resonators can operate simultaneously in different resonance modes at one resonance frequency and enables parallel, independent signal detection with different sensitivity profiles; this feature is used to carry out the SENSE method.</p> |
