A method for acquiring magnetic resonance measurement data from a subject, comprising:loading a control protocol into a control computer of a magnetic resonance apparatus, said control protocol causing said control computer to operate a magnetic resonance data acquisition scanner of the apparatus to acquire magnetic resonance data from a subject in a data acquisition sequence;
in said control computer, automatically determining sequence control data that are relevant to the control protocol, said sequence control data defining different functional sub-sequences of said acquisition sequence, wherein said sub-sequences cause nuclear spins in at least two sub-volumes of the subject to be simultaneously manipulated or used to acquire said magnetic resonance data;
in said control computer, for each functional sub-sequence, determining a respective effective volume dependent on the sub-volumes that are associated with the respective sub-sequence;
in said control computer, for each effective volume, individually determining applicable underlying conditions that exist in the data acquisition scanner for the determined sequence control data and for the respective effective volumes determined for the associated sub-volumes;
in said control computer, generating control signals for operating said data acquisition scanner from said sequence control data, said effective volumes, and said underlying conditions in order to perform said acquisition sequence with the respective sub-sequences being individually locally optimized for each effective volume of an associated sub-volume; and
making the generated control signals available from the control computer in electronic form while operating the data acquisition scanner.

SYSTEM AND METHOD FOR IMAGE PROCESSING WITH HIGHLY UNDERSAMPLED IMAGING DATA

Arizona Board of Regents ...

1. A system for processing magnetic resonance imaging data from an MRI device, comprising:an interface configured to receive the imaging data generated by the MRI device, the imaging data being generated using a multi-echo spin-echo (MESE) pulse sequence and being highly undersampled;
a set of training curves generated from imaging data for a range of expected T2 values;
a set of principal components derived from the set of training curves, the principal components being representative of T2 decay curves in the presence of indirect echoes generated by imperfections in the radio frequency refocusing pulses associated with the MRI device, wherein the refocusing pulses are not 180° across the entire imaging slice/volume; and
a processor configured to apply the set of principal components to the imaging data to compensate for the imperfections in the refocusing pulses used in the MRI device that distort the generated imaging data to thereby generate a corrected T2 map that reduces T2 value dependence on the imperfection in the MRI device and to display a more accurate MRI image.

METHOD FOR CORRECTING PHASE OFFSETS IN QUANTITATIVE CHEMICAL SHIFT ENCODED MAGNETIC RESONANCE IMAGING

Wisconsin Alumni Research...

1. A method for correcting phase errors in chemical shift encoded data acquired with a magnetic resonance imaging (MRI) system, the steps of the method comprising:(a) acquiring chemical shift encoded data from a subject using an MRI system operating a pulse sequence that induces linear phase errors in multiple different echoes;
(b) generating first complex-valued estimates of a water image, a fat image, and a field map using a complex fitting of the acquired chemical shift encoded data, wherein the initial complex-valued estimates are indicative of a proton density fat fraction dynamic range of zero to one hundred percent;
(c) generating magnitude estimates of a water image and a fat image independently on a voxel-by-voxel basis using a magnitude fitting of the acquired chemical shift encoded data in which the first complex-valued estimates of the water image and the fat image are used as initial values;
(d) generating second complex-valued estimates of a water image and a fat image independently on a voxel-by-voxel basis using a complex fitting of the acquired chemical shift encoded data in which the first complex-valued estimates of the water image, the fat image, and the field map are used as initial values;
(e) producing a phase-corrected water image and a phase-corrected fat image by estimating linear phase offsets associated with the linear phase errors induced by the pulse sequence, wherein estimating the linear phase offsets is based on minimizing an objective function that includes a difference between the magnitude estimates of the water image and the fat image and the second complex-valued estimates of the water image and the fat image; and
(f) generating a proton density fat fraction map based on the phase-corrected water image and the phase-corrected fat image.

1. A gradient coil arrangement comprising:an integrated magnet device for use in an magnetic resonance imaging (MRI) system comprising:
field-shifting shield magnets;
