Patent number: 12229600Abstract: Parameters of a pool of computing resources to be utilized for machine learning tasks from a set of entities are stored, including a category of the computing resources, and a post-task-completion retention period during which, after completion of a task, at least a portion of data stored at the resource is not to be deleted. A compute instance of the pool is assigned to a task requested from the set of entities after determining that one or more configuration settings of the instance satisfy a preference indicated in the request for the task, and that the retention period of the instance relative to a completion of an earlier task on the instance has not expired. A result of the task is stored.Type: GrantFiled: September 22, 2021Date of Patent: February 18, 2025Assignee: Amazon Technologies, Inc.Inventors: Ramyanshu Datta, Zhihan Li, Arun Babu Nagarajan, Arvind Sowmyan, Kohen Berith Chia, Wei You, Ishaaq Chandy, Kunal Mehrotra, Andrea Olgiati, Lakshmi Naarayanan Ramakrishnan, Saurabh Gupta

Patent number: 9675820Abstract: Methods and systems for passively detecting stable cavitation and enhancing stable cavitation during sonothrombolysis are provided. The method of passively detecting stable cavitation includes providing a determined level of ultrasonic energy and detecting a scattered level of ultrasonic energy. The system for inducing and passively detecting stable cavitation includes a dual-element annular transducer array configured to provide a fundamental ultrasonic frequency and to detect an ultrasonic frequency that is a derivative of the fundamental frequency. The method of enhancing stable cavitation includes administering a nucleating agent and a thrombolytic agent to a treatment zone, providing a determined level of ultrasonic energy, and detecting a scattered level of ultrasonic energy.Type: GrantFiled: January 28, 2016Date of Patent: June 13, 2017Assignee: University of CincinnatiInventors: Christy K.

Patent number: 9398898Abstract: Spatially distinct Spectral Doppler information is acquired. Spatially distinct transmit beams are formed at a same time or in parallel. One or more receive beams are formed in response to each transmit beam, providing samples for a plurality of laterally spaced locations. A spectrum is determined for each of a plurality of spatial locations. In another approach, samples are acquired for different regions at different times. The scanning for each region is interleaved based on the anatomic operation. Since spectral estimation relies on a time-continuous series of transmission and reception, the scanning for a region occurs over a sufficient period for spectral estimation before the scanning for a different region occurs. By using anatomic operation, sufficient time is provided for spectral estimation. Due to anatomic operation, different regions are associated with flow at different times.Type: GrantFiled: February 23, 2011Date of Patent: July 26, 2016Assignee: Siemens Medical Solutions USA, Inc.Inventors: Wilko Wilkening, Saurabh Datta, Paul Freiburger, Chi-Yin Lee

Patent number: 9320496Abstract: Volumetric quantification is provided in medical diagnostic ultrasound. By acquiring both B-mode and color flow data without stitching or acquiring in real-time at tens of volumes a second, more reliable quantification may be provided. Using multiple regions of interest in a volume may allow for more accurate and/or complete flow information, such as averaging flow from different locations in the same structure (e.g., use preservation of mass to acquire multiple measures of the same flow).Type: GrantFiled: February 25, 2010Date of Patent: April 26, 2016Assignee: Siemens Medical Solutions USA, Inc.Inventors: Saurabh Datta, Seshadri Srinivasan, Christophe Duong

Patent number: 9033887Abstract: A mitral valve is detected in transthoracic echocardiography. The ultrasound transducer is positioned against the chest of the patient rather than being inserted within the patient. While data acquired from such scanning may be noisier or have less resolution, the mitral valve may still be automatically detected. Using both B-mode data representing tissue as well as flow data representing the regurgitant jet, the mitral valve may be detected automatically with a machine-learnt classifier. A series of classifiers may be used, such as determining a position and orientation of a valve region with one classifier, determining a regurgitant orifice with another classifier, and locating mitral valve anatomy with a third classifier. One or more features for some of the classifiers may be calculated based on the orientation of the valve region.Type: GrantFiled: May 30, 2013Date of Patent: May 19, 2015Assignees: Siemens Corporation, Siemens Medical Solutions USA, Inc., Siemens AktiengesellschaftInventors: Razvan Ioan Ionasec, Dime Vitanovski, Yang Wang, Bogdan Georgescu, Ingmar Voigt, Saurabh Datta, Dorin Comaniciu

Patent number: 9033883Abstract: Velocities are unaliased using conditional random fields. To constrain the energy minimization function, a global term includes a measure of a level of aliasing. In one example, the measure of the level of aliasing is based on a change in volume, such as the volume of the left ventricle. The unaliasing is performed along one or more surfaces, such as surfaces intersecting the mitral annulus and the left ventricle outflow tract. The anatomy used is identified and/or tracked using one or more machine-learnt detectors. Both B-mode and velocity information may be used for detecting the anatomy.Type: GrantFiled: November 20, 2012Date of Patent: May 19, 2015Assignee: Siemens CorporationInventors: Yang Wang, Bogdan Georgescu, Saurabh Datta

Patent number: 9028413Abstract: Flow estimation is provided. The flow is predicted. A mathematical, logic, machine learning or other model is used to predict flow. For example, the boundary conditions associated with a previous flow, the previous flow, and current boundary conditions are used to predict the current flow. The current flow is corrected using the predicted flow. Velocities may be unaliased based on the predicted flow. The predicted flow may replace the current flow. Prediction may additionally or alternatively be used in determination of lateral or elevational flow.Type: GrantFiled: March 8, 2010Date of Patent: May 12, 2015Assignee: Siemens Medical Solutions USA, Inc.Inventors: Seshadri Srinivasan, Saurabh Datta, Helene Houle

Publication number: 20130245441Abstract: Pressure-volume analysis is provided in medical diagnostic ultrasound imaging. The heart of a patient is scanned multiple times during a given cycle. B-mode and flow information are obtained for various times. The flow information is used to estimate pressure over time. A reference pressure, such as from a cuff, may be used to calibrate the pressure waveform. The B-mode information is used to determine a heart volume over time, such as a left ventricle volume over time. The heart volume over time and pressure over time are plotted, providing a pressure-volume loop. The pressure-volume loop is determined non-invasively with ultrasound.Type: ApplicationFiled: March 13, 2012Publication date: September 19, 2013Applicant: Siemens Medical Solutions USA, Inc.Inventor: Saurabh Datta
