Claims38
A magnetic resonance imaging system (MRI) comprising:
- a main magnet having a field strength less than 1.0 Tesla;
- a gradient coil assembly;
- an RF coil system;
- and
- a control system configured for acquisition and processing of magnetic resonance imaging data from a human patient and configured to utilize a sparse sampling imaging technique without parallel imaging and to utilize an RF bandwidth to maintain artifacts due to chemical shift and magnetic susceptibility below one half of a millimeter.
A computer program product comprising a non-transient, machine-readable medium storing instructions which, when executed by at least one programmable processor, cause the at least one programmable processor to perform operations comprising:
- acquiring magnetic resonance imaging data from a human patient through a magnetic resonance imaging system (MRI) having a main magnet with a field strength less than 1.0 Tesla, a gradient coil assembly and an RF coil system, the acquiring utilizing a sparse sampling imaging technique without parallel imaging and utilizing an RF bandwidth to maintain artifacts due to chemical shift and magnetic susceptibility below one half of a millimeter;
- and
- processing the magnetic resonance imaging data, the processing including reconstructing images of the human patient.
