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
