Publication number: 20210205025Abstract: A controller (240/340) for simultaneously tracking multiple interventional medical devices includes a memory (242/342) that stores instructions and a processor (241/341) that executes the instructions. When executed by the processor (241/341), the instructions cause the controller to execute a process that includes receiving timing information from a first signal emitted from an ultrasound probe (252/352) and reflective of timing when the ultrasound probe (252/352) transmits ultrasound beams to generate ultrasound imagery. The process executed by the controller also includes forwarding the timing information to be available for use by a first acquisition electronic component (232/332). The first acquisition electronic component (232/332) also receives sensor information from a first passive ultrasound sensor (S1) on a first interventional medical device (212/312).Type: ApplicationFiled: June 6, 2019Publication date: July 8, 2021Inventors: RAMON QUIDO ERKAMP, HENDRIK ROELOF STAPERT, GUNTHER LAMPARTER, AMEET KUMAR JAIN, ALVIN CHEN, SHYAM BHARAT, KUNAL VAIDYA, FRANCOIS GUY GERARD MARIE VIGNON

Patent number: 10945702Abstract: A diagnostic ultrasound system for carotid artery diagnosis has a two dimensional array probe with a low element count and relatively large element size which can cover an area of the carotid artery at its bifurcation. The elements are operated independently with no phasing, and detect Doppler flow spatially beneath each element. The system produces maps of carotid blood flow in two or three dimensions and can assemble an extended view of the flow by matching segments of the carotid flow as the probe is moved over the vessel. Once the carotid artery has been localized, the degree of stenosis is assessed by automated measurements of peak systolic velocity and blood flow turbulence.Type: GrantFiled: July 2, 2014Date of Patent: March 16, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Krishnamoorthy Palanisamy, Sushanth Govinahallisathyanarayana, Rajendra Singh Sisodia, Nagaraju Bussa, Shankar Mosur Venkatesan, Shriram Sethuraman, John Petruzzello, Ajay Anand, Shiwei Zhou, Ramon Quido Erkamp, Vikram Basawaraj Patil Okaly

Publication number: 20200237337Abstract: A method for using an interactive visual guidance tool for an imaging acquisition and display system and configured for user navigation with respect to a blockage of a field of view detects, and spatially defines, the blockage. It also integrates, with the image for joint visualization, an indicium that visually represents the definition. The indicium is moved dynamically according to movement, relative to the blockage, of the field of view. The indicium can be shaped like a line segment, or two indicia can be joined in a āVā shape to frame a region of non-blockage. The defining may be based on determining whether ultrasound beams in respective directions are blocked. Included, for deriving the image, in some embodiments are imaging channels for receiving image data for which a metric of coherence, i.e., similarity among channel data, is computed. The determination for a direction is based on the metric for locations in that direction.Type: ApplicationFiled: April 1, 2020Publication date: July 30, 2020Inventors: SHENG-WEN HUANG, EMIL GEORGE RADULESCU, RAMON QUIDO ERKAMP, SHOUGANG WANG, KARL ERHARD THIELE, DAVID PRATER

Patent number: 10368832Abstract: Issuance of ultrasound pulses to a volume and receiving echo data is followed by estimating, based on the received data, center frequency subvolume-by-subvolume. Distinguishing between heart and lung tissue occurs based on a result of the estimating, and may include automatically identifying a spatial boundary (332) between the heart and lung tissue (324, 328), or a user display of center frequencies that allows for visual distinguishing. The issuance can include issuing, ray line by ray line, pair-wise identical, and/or pair-wise mutually inverted, ultrasound pulses. Center frequency calculations may be made for incremental sampling locations of respective imaging depth along each of the A-lines generated from echo data of the rays. The distinguishing might entail averaging center frequencies for locations along an A-line, and applying a central frequency threshold to the average.

Patent number: 10357224Abstract: A medical ultrasound acquisition-data analysis device acquires channel data (144) via ultrasound received on the channels, uses the acquired channel data to estimate data coherence and derive dominance of an eigen-value of a channel covariance matrix and, based on the estimate and dominance, distinguishes microcalcifications (142) from background. Microcalcifications may then be made distinguishable visually on screen via highlighting, coloring, annotation, etc. The channel data operable upon by the estimating may have been subject to beamforming delays and may be summed in a beamforming procedure executed in the estimating. In the estimating and deriving, both field point-by-field point, multiple serial transmits (116, 118) may be used for each field point. In one embodiment results of the estimating and deriving are multiplied point-by-point and submitted to thresholding.Type: GrantFiled: March 12, 2014Date of Patent: July 23, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Jean-Luc Robert, Sheng-Wen Huang, Emil George Radulescu, Francois Guy Gerard Marie Vignon, Ramon Quido Erkamp
