20090219023 | Method of and Software Application for Quantifying Objects in Magnetic Resonance Images via Multiple Complex Summations - A method comprises digitally representing a volume of space as a plurality of voxels and assigning real and imaginary values derived from magnetic resonance imaging data of the space to each of the voxels. Furthermore, the method comprises a steps of calculating a first complex summation of the real and imaginary values of a first set of the voxels, and calculating a second complex summation of the real and imaginary values of a second set of the voxels. Each set of voxels represents a different region of the volume of space. The regions are concentric. The method also comprises steps of using the first and second summations, along with another value quantitatively calculated from the magnetic resonance imaging data, to calculate a value that is dependent upon the approximate magnetic moment of an object within the volume of space, and digitally representing and storing said value. | 09-03-2009 |
20090261824 | Geometry Based Field Prediction Method for Susceptibility Mapping and Phase Artifact Removal - The present invention provides a method of handling rapid phase aliasing in magnetic resonance images arising from local magnetic susceptibility differences.

20150323635 | METHOD AND APPARATUS FOR MAGNETIC RESONANCE IMAGING WITH RADIO FREQUENCY PULSES GENERATED ACCORDING TO PHASE CRITERIA - In this disclosure, a process of imaging a target object using magnetic resonance (MR) includes an MRI scanner scanning the target object using a first transmit RF pulse. A processor associated with the MRI scanner can acquire magnitude and/or phase data associated with a first RF signal produced (or echoed) by the target object responsive to the MRI scan. The processor can determine a second transmit RF pulse for use to scan the target object based on the acquired data and according to a given phase criterion. The phase criterion can be configured to enforce mitigation of a phase distribution estimated based on the acquired data. | 11-12-2015 |
