Patent number: 10952706Abstract: An ultrasound microbeamformer for one or more transducer arrays includes a plurality of channels, each of which has two transmitters and a receiver which is selectively coupled to two or more transducer elements by T/R switches and dynamically switchable receive switches (RXSW). The transmitters enable different transducers to be actuated differently, such as transmitting a high frequency pulse or waveform with one transmitter and a low frequency pulse or waveform with the other transmitter. The transmitters may both be used during the same transmit-receive cycle to simultaneously transmit and receive both high and low frequency signals for the formation of a common image.Type: GrantFiled: November 23, 2016Date of Patent: March 23, 2021Assignee: Koninklijke Philips N.V.Inventor: Steven Russell Freeman

Patent number: 10939896Abstract: Battery-powered ultrasound scanner for veterinary applications, and operating method. Ultrasound measurements are processed to determine if an ultrasound probe is not being moved and, if it is not being moved, the average rate at which ultrasound pulses is generated, thereby reducing power consumption. The average rate at which ultrasound pulses are generated is reduced step-wise if non-movement persist but increase rapidly when movement recommences.Type: GrantFiled: February 28, 2018Date of Patent: March 9, 2021Assignee: IMV IMAGING (UK) LTDInventors: Adam Somerville, John Fothergill

Patent number: 10925577Abstract: A Multiple Aperture Ultrasound Imaging (MAUI) probe or transducer is uniquely capable of simultaneous imaging of a region of interest from separate physical apertures of ultrasound arrays. The probe can include separate backing plates configured to secure the ultrasound arrays in predetermined positions and orientations relative to one another. Some embodiments of the probe include flex circuit connected to the ultrasound arrays. In additional embodiments, a flex/PC board comprising flex connectors and an array of terminals is connected to the ultrasound arrays. Algorithms can solve for variations in tissue speed of sound, thus allowing the probe apparatus to be used virtually anywhere in or on the body.Type: GrantFiled: October 16, 2017Date of Patent: February 23, 2021Assignee: MAUI IMAGING, INC.Inventors: Sharon L. Adam, David M. Smith, Donald F. Specht, Kenneth D. Brewer

Patent number: 10925634Abstract: A sterile needle guide system for directing needle entry during a medical procedure includes a needle guide plate extending in a plane and having a plurality tubular needle guides extending through the plate at an normal angle to the plane of the plate. A movable base translatable along an axis normal to the plane of the plate defines features to removably receiving the plate. A calibrator attachment is removably securable to the needle guide plate and enables attachment of the needle guide plate to the base and calibration of the needle guide position in a sterile manner. In embodiments, the movable base includes a base body, a rail component over which the base body is movably coupled, and a ratchet mechanism for releasably securing the base body to the rail component. The disclosed needle guide system enables the needle guide plate to be positioned directly adjacent to the patient's perennial to reduce the curvature of deflection of the needle upon entry into the patient's body during the biopsy procedure.Type: GrantFiled: November 19, 2018Date of Patent: February 23, 2021Assignee: HARMONUS, INC.Inventors: Peter Tia, Phillip John Marathakis
