20100220909 | METHOD AND APPARATUS FOR REDUCING IMAGE ARTIFACTS - A method and apparatus are provided for reducing motion related imaging artifacts. The method includes determining an internal motion for of two regions of the object, each region having a different level of motion, scanning the first region using a first scan protocol based on the motion, scanning a second region using a second different scan protocol based on the motion, and generating an image of the object based on the first and second regions. | 09-02-2010 |
20110158477 | REDUCING EFFECTS OF ROTATIONAL MOTION - A method and system for improving image quality by correcting errors introduced by rotational motion of an object being imaged is provided. The object is associated with a fiducial mark. The method provides a computer executable methodology for detecting a rotation and selectively reordering, deleting and/or reacquiring projection data. | 06-30-2011 |
20120206140 | System And Method For Generating A Magnetic Resonance Image Using Prospective Motion Correction And Parallel Imaging - 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. | 08-16-2012 |
20140347048 | SYSTEMS AND METHODS FOR REDUCING MAGNETIC RESONANCE (MR) IMAGING ACOUSTIC NOISE IN MR INFLOW IMAGING - Systems and methods for reducing acoustic noise in a Magnetic Resonance Imaging (MRI) are provided. One method includes applying a labeling phase of an arterial spin labeling (ASL) pulse sequence to a region of interest, applying a three-dimensional (3D) radial pulse sequence to the region of interest to generate a tag image, applying a control phase of the ASL pulse sequence to the region of interest, and applying the 3D radial pulse sequence to the region of interest to generate a control image. | 11-27-2014 |

20160051490 | NEUROPROTECTIVE EFFECT OF CAROTENOIDS IN BRAIN - The present invention provides use of composition containing molecular dispersions of carotenoids for the prevention of neurodegenerative disorders which are safe for human consumption and are particularly useful as dietary supplements for nutrition and health promoting benefits. The present invention particularly relates to the use of highly water soluble composition with enhanced bioavailability containing at least 80% by weight of total xanthophylls, out of which the trans-lutein content is 80-95% w/w; (R,R)-zeaxanthin is 14-20% w/w; (R,S)-zeaxanthin is 0.01-1% w/w and traces of other carotenoids derived from the plant extracts/oleoresin containing xanthophylls/xanthophylls esters. The present invention also provides use of the said composition in treatment of neurodegenerative disorders when co-administered along with reduced dose of Levodopa and Carbidopa. | 02-25-2016 |

20100138703 | IDENTIFYING AND MONITORING ASYNCHRONOUS TRANSACTIONS - Monitoring asynchronous transactions in a computing environment is disclosed. A first unique identifier is determined when a first method executes. The identifier is associated with an asynchronous transaction. A second unique identifier is determined when a second method executes. If it is determined that the first unique identifier and the second unique identifier match, then is it determined that the asynchronous transaction started with the first method and completed with the second method. In one embodiment, code that identifies a routine that has instructions for determining the first unique identifier at runtime is added to the first method, and code that identifies a routine that has instructions for determining the second unique identifier at runtime is added to the second method. | 06-03-2010 |

20090150908 | MONITORING MULTI-PLATFORM TRANSACTIONS - A monitoring system monitors and provides performance data for a transaction performed by multiple applications over different platforms. The monitoring system provides the ability to initiate collection of transaction data from applications on multiple platforms. A request for a multi-platform transaction such as an SAP transaction is received by a first application, such as a JAVA application, on a first platform. Processing of the transaction triggers the first application to invoke a second application, such as an ABAP application, on a second platform. Code inserted into the first application intercepts the invocation of the second application, remotely executes a function on the second platform while providing a transaction identifier to an application server providing the second platform, and returns control back to the first application, which proceeds to invoke the second application to complete the multi-platform transaction. Performance data for the first application and the second application is accessed and correlated based on the transaction identifier to enable reporting of transaction performance over the two platforms. | 06-11-2009 |
