A method for generating a magnetic resonance (MR) image includes acquiring MR data from each of a plurality of RF coils and applying a prospective motion correction method to the MR data for each RF coil including determining a set of motion measurements that include a scan plane orientation associated with each data point in the MR data. The MR data for each RF coil is divided into a plurality of scan plane orientation groups based on motion changes. A set of unaliasing coefficients is generated for each scan plan orientation group and applied to the MR data to synthesize data for each RF coil. The acquired MR data and synthesized data for each RF coil is combined to generate a scan plane orientation data set. Each scan plane orientation data set is combined to generate a complete k-space data set.

System and method for generating a magnetic resonance image using prospective motion correction and parallel imaging

Present embodiments are directed towards a magnetic resonance imaging method. In one embodiment, the method includes (a) performing a first magnetic resonance imaging sequence including: (i) a first preparatory composite spin locking pulse sequence having a spin lock pulse bounded by similarly oriented spin tipping pulses; and (ii) an acquisition pulse sequence to acquire first magnetic resonance data. The method further includes (b) performing a second magnetic resonance imaging sequence including: (i) a second preparatory composite spin locking pulse sequence having a spin lock pulse bounded by oppositely oriented spin tipping pulses; and (ii) an acquisition pulse sequence to acquire second magnetic resonance data. The method also includes (c) storing the first and second magnetic resonance data.

Systems, methods and apparatus are provided through which multi-slice acquisitions of T1&#x3c1;-weighted data are combined to form quantitative T1&#x3c1; values without retrospective correction for the contaminating effects of other MR relaxation parameters.

Systems, methods and apparatus for multi-slice quantitative imaging

An MRI system includes a detector system which receives an ECG signal from a patient being scanned and produces a gating signal. The gating signal is produced when a detected peak in the ECG signal meets a set of R-wave criteria which includes a specified positive slope on the leading segment of the detected peak, a minimum duration of the leading segment, specified negative slope on the segment trailing the detected peak and a minimum peak amplitude.
