Patent number: 11540718Abstract: An imaging steering apparatus includes sensors and an imaging processor configured for: acquiring, via multiple ones of the sensors and from a current position (322), and current orientation (324), an image of an object of interest; based on a model, segmenting the acquired image; and determining, based on a result of the segmenting, a target position (318), and target orientation (320), with the target position and/or target orientation differing correspondingly from the current position and/or current orientation. An electronic steering parameter effective toward improving the current field of view may be computed, and a user may be provided instructional feedback (144) in navigating an imaging probe toward the improving. A robot can be configured for, automatically and without need for user intervention, imparting force (142) to the probe to move it responsive to the determination.Type: GrantFiled: December 5, 2014Date of Patent: January 3, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Irina Waechter-Stehle, Sabine Mollus, Christian Buerger, Emil George Radulescu, Sheng-Wen Huang, Juergen Weese

Patent number: 11506770Abstract: An ultrasound imaging system probe comprises an imaging transducer head and a reception circuit for processing received reflected ultrasound signals. The reception circuit comprises an analogue to digital sigma delta converter which comprises a closed loop which comprises a tunable band pass filter. This enables the analog to digital converter to process only the desired frequency band. The ADC conversion bandwidth and ENOB are in this way programmable giving a more efficient probe design, and also enabling analog to digital conversion early in the signal processing chain.Type: GrantFiled: December 9, 2016Date of Patent: November 22, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventor: Sotir Filipov Ouzounov

Patent number: 11497436Abstract: Apparatuses, systems, and methods for performing real-time analysis of bone tissue during a surgical procedure are disclosed herein. In some embodiments, the method includes receiving at least one measurement of at least one tissue sample from a hybrid multi-wavelength photoacoustic measurements (MWPM) component. The method can also include identifying one or more reference cases, from a plurality of reference cases, based on correlations between the at least one measurement and previous measurements in each of the plurality of reference cases. Once the reference cases are identified, the method can include determining at least one bone condition of the patient and sending the at least one determined bone condition to a computing device accessible by a surgeon. In some embodiments, the method also includes creating a three-dimensional (3D) map the tissue sample using the at least one measurement and sending the 3D map to the computing device.Type: GrantFiled: May 17, 2022Date of Patent: November 15, 2022Assignee: IX Innovation LLCInventors: Jeffrey Roh, Justin Esterberg, John Cronin, Seth Cronin, Michael John Baker

Patent number: 11306583Abstract: Systems and methods for transmitting power and information using acoustic energy produced by transducers are provided. The systems have particular application for powering and communication with electronics through drilling and pipe systems. Pairs of acoustic wedges holding transducers are provided for sending energy and information through a substrate which may be a steel pipe. Each wedge has an angled transducer which can be used to produce shear waves. The waves propagate through the substrate and are received by a second acoustic wedge. The shear waves, on reaching the second acoustic wedge, are converted back into electrical signals by a second transducer. Tangential shear waves, high, shallow wave transmission angles, and direct steel-steel bonding between wedges and substrates may be used.Type: GrantFiled: July 15, 2020Date of Patent: April 19, 2022Assignee: Rensselaer Polytechnic InstituteInventors: Henry A.
