Patent number: 11678859Abstract: Systems and methods for generating an electromechanical map are disclosed herein. The methods includes obtaining ultrasound data comprising a series of consecutive image frames and radio frequency (RF) signals corresponding to the location in the heart; measuring displacements and strains based on the ultrasound data to determine an electromechanical activation in the location; converting the ultrasound data into a series of isochrone maps; and combining the series of isochrone maps to generate the electromechanical map. The electromechanical map illustrates the electromechanical activation and internal wall structures of the heart.Type: GrantFiled: September 16, 2019Date of Patent: June 20, 2023Assignee: THE TRUSTEES OF COLUMBIA UNIVERSITY IN THE CITY OF NEW YORKInventors: Elisa Konofagou, Pierre Nauleau, Elaine Wan, Lea Melki, Julien Grondin

Publication number: 20220022955Abstract: System and methods for monitoring cardiac ablation procedures are disclosed. The system can comprise an imaging device and an image processor. The imaging device can be configured to acquire successive frames and radio frequency signal data of a heart. The image process, coupled to the imaging device, can be configured to obtain a signal envelope of the radio frequency signal data, generate a strain map based on the signal envelope, apply a strain threshold to the strain map for classification of lesion tissue, and provide an image which visualizes lesion formation during the cardiac ablation procedures in real-time.Type: ApplicationFiled: October 4, 2021Publication date: January 27, 2022Applicant: THE TRUSTEES OF COLUMBIA UNIVERSITY IN THE CITY OF NEW YORKInventors: Elisa E. KONOFAGOU, Vincent SAYSENG, Elaine WAN

Publication number: 20200163646Abstract: Techniques for mapping behavior of a heart include acquiring a series of two or more images of the heart. The series of images is taken at one or more pixel locations, each pixel location corresponding to a region of the heart. Image data corresponding to the pixel locations can be obtained, and a periodicity of the image data measured for each of the pixel locations over the series of images. The periodicity corresponds to an electromechanical signal of the heart in the region corresponding to the measured one or more pixel locations.Type: ApplicationFiled: November 7, 2019Publication date: May 28, 2020Applicant: THE TRUSTEES OF COLUMBIA UNIVERSITY IN THE CITY OF NEW YORKInventors: Elisa E. Konofagou, Jean Provost, Alok Gambhir, Alexandre Costet, Elaine Wan, Julien Grondin

Patent number: 8234139Abstract: A system for manufacturing a product receives a formulation specification that includes a plurality of ingredients for the product. The system further receives cost information for the ingredients and inventory information. The system then generates a least cost formulation for the product based on the formulation specification, cost information and inventory information.Type: GrantFiled: October 15, 2007Date of Patent: July 31, 2012Assignee: Oracle International CorporationInventors: Elaine Wan, Thomas Daniel, Rajender Nalla, Graceann Iannacchino, Karen Theel

Publication number: 20090187265Abstract: A system that determines product quantities for a process manufacturing formula that generates a first product and a second product receives a quantity of a first ingredient and a quantity of a second ingredient. The first and second ingredients contribute to a formula yield. The system further receives a quantity of a byproduct of the formula and a percentage of the formula for the output first product and a percentage of the formula for the output second product. The system then automatically determines a first product quantity based on the quantity of the first ingredient, the quantity of the second ingredient, the quantity of the byproduct of the formula, and the percentage of the formula for the first product.Type: ApplicationFiled: January 23, 2008Publication date: July 23, 2009Applicant: Oracle International CorporationInventors: Elaine WAN, Thomas Daniel, Kapil Motupalli, Rahul Krishan, Rajendar Nalla

Publication number: 20050060214Abstract: A computer implemented method for managing a stability or shelf life study is provided. Requirements for a stage in a plurality of stages are determined and interfaces are output that define the requirements. Information may then be input for fulfilling the requirements. The input information is then validated against business rules that define logic to determine if the input information is acceptable. The input information is then stored.Type: ApplicationFiled: September 17, 2003Publication date: March 17, 2005Applicant: Oracle International CorporationInventors: Karen Theel, Elaine Wan, Sanjay Rastogi, Brenda Stone, Chetan Nagarbandhara, Richard Persen
