Publication number: 20230335264Abstract: Point of care ultrasound examinations can be routed and processed in a computer network via the platforms, systems, and methods disclosed herein. The platforms, systems, and/or methods can use computing devices that are configured to provide a client application and at least one server processor for enabling use of an application. The examinations can be managed using an interface that allows an administrator user to assign user roles to other users, which can enable interactions within the network for processing and serving an ultrasound exam object. The ultrasound exam object can include patient data, images, and/or other relevant information.Type: ApplicationFiled: April 14, 2023Publication date: October 19, 2023Inventors: Annik RAGSDALE, Michael PUPO, Ann LAMBERT, Sandeep AKKARAJU, Drake GUENTHER

Publication number: 20230129012Abstract: Acoustic imaging artifacts produced by imaging systems and devices can be reduced or eliminated by including a multisink medium in the systems or devices. The multisink material can be disposed between an acoustically reflective component of the imaging system or device and an ultrasound transducer of the imaging system or device. Inclusion of a multisink medium that is thermally conductive and acoustically non-conductive can reduce acoustic imaging artifacts while maintaining or improving heat management within imaging systems and devices.Type: ApplicationFiled: October 21, 2021Publication date: April 27, 2023Inventors: Killian SULLIVAN, Huseyin Kagan OGUZ, Anthony BROCK, Michael CONROY, Thomas TARTER, Drake GUENTHER, Brian BIRCUMSHAW

Patent number: 10863972Abstract: An apparatus includes a memory device with computer readable instructions and a processor configured to execute the computer readable instructions encoded on the memory device. The processor, in response to executing the computer readable instructions, obtains an ensemble of ultrasound images with diversity in an ensemble dimension, extracts a sub-set of data from each of the images, constructs a data matrix with the extracted data, wherein the data matrix has a dimension of space versus the ensemble dimension, identifies a largest eigenvalue(s) and a corresponding eigenvector(s) in the data matrix, computes a coherent signal projection matrix with the identified corresponding eigenvector(s), filters the data matrix with the coherent signal projection, and generates an ultrasound image with the filtered data matrix.Type: GrantFiled: March 27, 2017Date of Patent: December 15, 2020Assignee: B-K Medical ApSInventor: Drake A. Guenther

Patent number: 9064321Abstract: Methods, systems and system components for optimizing contrast resolution of an imaging or sensing system utilizing multiple channels of broadband data associated with an array of transducers. Channels of data are filtered by passing the channels of data through finite impulse response (FIR) filters on each channel. The filters each have multiple taps having tap weights pre-calculated as a function of distance of the array from an object that energy is being transmitted to or reflected from. The weights are pre-computed through a deterministic equation based on an a priori system model.Type: GrantFiled: June 2, 2014Date of Patent: June 23, 2015Assignee: University of Virginia Patent FoundationInventors: William F. Walker, Drake A. Guenther, Kevin Owen
