Patent number: 10324624Abstract: According to examples, an apparatus may include a processor and a non-transitory computer readable medium storing instructions that cause the processor to classify files stored on a source storage into files for deletion and files for migration based on a storage policy and meta-data, generate aliases to link the files classified for migration to a location on a target storage, copy the files classified for migration from the source storage to the linked location on the target storage, and determine whether the files copied onto the target storage are identical to the files classified for migration on the source storage using a digital key. In response to a determination that the copied files are identical to the files classified for migration, the processor may activate the generated aliases and may decommission the source storage.Type: GrantFiled: June 26, 2017Date of Patent: June 18, 2019Assignee: ENTIT SOFTWARE LLCInventors: Michael Peter McGrath, Veena Setlur, Samuel Hald Yan, Jay Fu, Meide Zhao, Kit Man So

Patent number: 8472690Abstract: Methods and systems are described for optimizing particular protocol parameters used in phase contrast magnetic resonance (PCMR) imaging. Optimal settings for PCMR protocol parameters such as coordinates, field of view (FOV), frequency/phase encoding lines, number of excitations (NEX), slice thickness, views per segment (VPS), and coil setting may be determined based upon the cut position/orientation of an image containing a vessel of interest, vessel size, length of the vessel segment, and heart rate. An optimal velocity encoding gradient (VENC) for PCMR may also be determined that both avoids aliasing and ensures an adequate signal-to-noise ratio.Type: GrantFiled: November 25, 2008Date of Patent: June 25, 2013Assignee: VASSOL Inc.Inventor: Meide Zhao

Patent number: 8000768Abstract: A method and system are disclosed for presenting anatomical and blood flow information contained in a magnetic resonance imaging (MRI) dataset. A three-dimensional (3D) representation of blood flow is generated which varies with time, referred to herein as a four-dimensional (4D) presentation or display. The system allows the visualization of the dynamics of blood flow and the visualization of anatomical information via the fusion of different types of MRI data sets.Type: GrantFiled: January 10, 2005Date of Patent: August 16, 2011Assignee: Vassol Inc.Inventors: Meide Zhao, Ning Meng, Anthony Curcio

Patent number: 7904136Abstract: A method and system are disclosed for evaluating symptomatic vertebrobasilar disease VBD which uses quantitative hemodynamic assessment in order to identify patients at high risk for stroke and provide appropriate guidance for intervention. Patients with symptomatic VBD may be considered for intervention to provide blood flow augmentation if evidence of sufficient flow compromise is present as defined by specific flow criteria, and treated medically otherwise.Type: GrantFiled: February 19, 2008Date of Patent: March 8, 2011Assignee: Vassol Inc.Inventors: Fady T. Charbel, Fady Charbel, II, Meide Zhao, Anthony Curcio, Sepideh Amin-Hanjani

Patent number: 7848554Abstract: A method and system are described for image registration using an information theoretic approach that can be used for correcting motion in blood flow studies as well as other applications. The joint probability distribution between two MRI (or other modality) images is estimated where the interpolation method is referred to as a continuous histogram.Type: GrantFiled: February 19, 2008Date of Patent: December 7, 2010Assignee: Vassol Inc.Inventors: Meide Zhao, Xiang He

Patent number: 7739090Abstract: A method and apparatus are provided for modeling circulation in a living subject. The method includes the steps of developing a model for living subjects in general and correcting the model to substantially conform to the overall cerebral physiology of the living subject. The method further includes the step of calculating a cerebral flow of the living subject based upon the corrected model and a selected cerebral blood flow perturbation.Type: GrantFiled: December 30, 2005Date of Patent: June 15, 2010Assignee: University of Illinois, Board of TrusteesInventors: Fady T. Charbel, Marlyn E. Clark, Meide Zhao

Patent number: 7515742Abstract: A method and system are described for compensating for the phase error in PCMR images due to eddy current effects. The phase noise due to eddy currents may be measured and characterized from phase images at selected regions near a vessel of interest.Type: GrantFiled: June 29, 2007Date of Patent: April 7, 2009Assignee: Vassol. Inc.Inventors: Meide Zhao, Tao Cai, Xiang He

Publication number: 20080146951Abstract: A method and system for evaluating the cerebral circulation of a patient is described. The arterial network of the brain is partitioned into a plurality of different regions where each region is supplied with blood by particular cerebral arteries. Volume flows into the regions are calculated from the measured volume flows of the cerebral arteries using quantitative magnetic resonance angiography. The cerebrovascular circulation of an individual patient may therefore be evaluated for the presence of disease by comparing the regional blood flows of the patient to normal values as obtained from population data.Type: ApplicationFiled: September 20, 2007Publication date: June 19, 2008Inventors: Meide Zhao, Sepideh Amin-Hanjani, Sean Ruland, Anthony Curcio, Lauren Ostergren, Fady T.
