| 20090072826 | MAGNETIC RESONANCE IMAGING WITH BIPOLAR MULTI-ECHO SEQUENCES - A method for magnetic resonance imaging (MRI) is provided. A magnetic resonance excitation is provided. A plurality of k-space echoes is acquired bi-directionally wherein at least one echo is an even echo acquired in a first direction and at least one echo is an odd echo acquired in a second direction opposite from the first direction. K-space echo realignment is corrected between the even and odd echoes. Field inhomogeneity induced artifacts are corrected. Chemical shift induced artifacts between at least two species are corrected. | 03-19-2009 |
| 20090072827 | INDEPENDENT PHASE MODULATION FOR EFFICIENT DUAL-BAND 3D IMAGING - A method for magnetic resonance imaging (MRI) a first volume and a second volume spaced apart from the first volume is provided. The first volume is excited with a first linearly varying phase with respect to k-space. The second volume is excited with a second linearly varying phase with respect to k-space, wherein the first linearly varying phase has a different slope than the second linearly varying phase. Data in k-space is acquired line by line. The acquired data in k-space is Fourier transformed to image space. An image is formed with a first volume image and a second volume image from the transformed data. Use of phase modulation allows imaging with a reduced field-of-view, which can result in faster scan times or improved performance of parallel imaging acquisition strategies. | 03-19-2009 |

| 20090306496 | AUTOMATIC SEGMENTATION OF ARTICULAR CARTILAGE FROM MRI - A method for musculoskeletal tissue segmentation used in magnetic resonance imaging (MRI) is provided. MRI image data is collected using at least two different contrast mechanisms. Voxel values from data from each contrast mechanism are used as elements of a feature vector. The feature vector is compared with classification boundaries to classify musculoskeletal tissue type of the voxel. The previous two steps are repeated for a plurality of voxels. An image is generated from the classified musculoskeletal tissue types for the plurality of voxels to provide a musculoskeletal segmentation image. | 12-10-2009 |
| 20100033179 | DISTORTION-FREE MAGNETIC RESONANCE IMAGING NEAR METALLIC IMPLANTS - A method for 3D magnetic resonance imaging (MRI) with slice-direction distortion correction is provided. One or more selective cross-sections with a thickness along a first axis is excited using a RF pulse with a bandwidth, wherein a selective cross-section is either a selective slice or selective slab. A refocusing pulse is applied to form a spin echo. One or more 2D encoded image signals are acquired with readout along a second axis and phase encoding along a third axis. Slice-direction distortion is corrected by resolving the position by resolving the frequency offset. | 02-11-2010 |
| 20110210732 | Balanced steady-state free-precession transient imaging using variable flip angles for a predefined signal profile - A magnetic resonance imaging system or method is provided including a balanced steady-state free-precession transient imaging (transient bSSFP) device capable of increasing the overall signal during transient bSSFP acquisition by fully or better utilization of the magnetization through variable RF flip angles. The transient bSSFP device is capable of generating a series of echoes with a desired transverse magnetization profile M | 09-01-2011 |

| 20090028700 | APPLIANCE PUMP - A pump for washing appliance is described. The pump has a pump casing in which an impeller is located. The pump casing has an inlet and outlet, and an inlet conduit extending from the inlet at a small angle above the horizontal. The ceiling includes a downwardly extending dividing wall section extending radially from a central location to a side wall of the casing. The dividing wall is positioned between the inlet outlet. The ceiling incorporates a ramped surface rising around the central location, between the outlet side and the inlet side of the dividing wall. The ramped surface is higher adjacent the inlet side than the outlet side of the dividing wall section so that when the impeller is not rotating, air inside the pump chamber will rise up the ramped surface through the inlet and up the inlet conduit. | 01-29-2009 |
