Publication number: 20240125927Abstract: Systems and methods for network-based ultrasound imaging are provided, which can include a number of features. In some embodiments, an ultrasound imaging system images an object with three-dimensional unfocused pings and obtains digital sample sets from a plurality of receiver elements. A sub-set of the digital sample sets can be electronically transferred to a remote server, where the sub-set can be beamformed to produce a series of two-dimensional image frames. A video stream made up of the series of two-dimensional images frames can then be transferred from the remote server to a display device.Type: ApplicationFiled: June 7, 2023Publication date: April 18, 2024Inventors: Josef R. CALL, Henry A. DAVIS, David M. SMITH, David J. SPECHT, Viet Nam LE, Lang J. MCHARDY, Joseph James DIGIOVANNI, II, Nathan W. OSBORN, Bruce R. RITZI

Publication number: 20240081787Abstract: A method of full-field or “ping-based” Doppler ultrasound imaging allows for detection of Doppler signals indicating moving reflectors at any point in an imaging field without the need to predefine range gates. In various embodiments, such whole-field Doppler imaging methods may include transmitting a Doppler ping from a transmit aperture, receiving echoes of the Doppler ping with one or more separate receive apertures, detecting Doppler signals and determining the speed of moving reflectors. In some embodiments, the system also provides the ability to determine the direction of motion by solving a set of simultaneous equations based on echo data received by multiple receive apertures.Type: ApplicationFiled: November 21, 2023Publication date: March 14, 2024Inventors: Donald F. SPECHT, Kenneth D. BREWER, David M. SMITH, Josef R. CALL, Viet Nam LE, Bruce R. RITZI

Publication number: 20230277158Abstract: A multiple aperture ultrasound imaging system may be configured to store raw, un-beamformed echo data. Stored echo data may be retrieved and re-beamformed using modified parameters in order to enhance the image or to reveal information that was not visible or not discernible in an original image. Raw echo data may also be transmitted over a network and beamformed by a remote device that is not physically proximate to the probe performing imaging. Such systems may allow physicians or other practitioners to manipulate echo data as though they were imaging the patient directly, even without the patient being present. Many unique diagnostic opportunities are made possible by such systems and methods.Type: ApplicationFiled: May 15, 2023Publication date: September 7, 2023Inventors: Josef R. CALL, Kenneth D.

Patent number: 7668186Abstract: A buffer management system for a data processing system can include a plurality of tokens wherein each token is associated with one of a plurality of buffers, and a plurality of first-in-first-out (FIFO) memories. Each FIFO memory can be associated with a stage of the data processing system and is configured to store at least one of the tokens. The buffer management system also can include control logic configured to determine a state of one or more selected buffers and transfer the token associated with the selected buffer from a source FIFO memory to a target FIFO memory. The target FIFO memory can be selected according to the state of the selected buffer.Type: GrantFiled: March 7, 2006Date of Patent: February 23, 2010Assignee: XILINX, Inc.Inventors: Roscoe Conkling Nelson, IV, Stacey Secatch, Thomas E.
