Sub-sampled moving table MRI for at least two adjacent fields of view

A magnetic resonance imaging apparatus for obtaining a dynamic image from a plurality of signals of an object moving relative to at least one RF receiving antenna, comprising:

• a patient table configured for movement through the bore of a magnet,
• at least one RF receiving antenna,
• means for providing a sensitivity map of the at least one RF receiving antenna at each position relative to the object determined by each of at least two adjacent fields of view (FOV) prior to imaging,
• means for sampling data from the object to be imaged for each of the at least two adjacent FOVs with a reduced number of phase encoding steps with respect to the full set thereof at a fixed position relative to the main magnetic field, and
• means for reconstructing an image from the sampled data, which sampled data are weighted with the sensitivity factor of the RF receiving antenna at the respective imaging position.

A computer readable medium on which is stored a program for forming a dynamic image with the magnetic resonance method by causing a computer to control the execution of:

• moving a patient table for through the bore of a magnet which operates a main magnetic field,
• sampling data from at least one RF receiving antenna array,
• providing a sensitivity map of the at least one RF receiving antenna array at each position relative to a region of interest of an object which region of interest includes at least two adjacent fields of view (FOV) prior to imaging,
• sampling data from the object to be imaged for each of the at least two FOVs with a reduced number of phase encoding steps with respect to the full set thereof at a fixed position relative to the main magnetic field, the sampled data of each FOV being folded into sampled data of an adjacent FOV, and
• reconstructing the image from the sampled signals, including weighting with the sensitivity factor of the RF receiving antenna array at the respective imaging position and unfolding the folded data.
