Patent number: 11918300Abstract: An ultrasound imaging system for needle insertion guidance uses a curved array transducer to scan an image field with unsteered beams as a needle is inserted into the image field. Due to differences in the angle of incidence between the radially directed beams and the needle, echoes will return most strongly from only a section of the needle. This section is identified in an image, and the angle of incidence producing the strongest returns is identified. Beams with this optimal angle of incidence are then steered in parallel from the curved array transducer to produce the best needle image. The steep steering angles of some of the steered beams can give rise to side lobe clutter artifacts, which can be identified and removed from the image data using dual apodization processing of the image data.Type: GrantFiled: January 15, 2019Date of Patent: March 5, 2024Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Shannon Renee Fox, Changhong Hu, Kyong Chang, James Robertson Jago, Thanasis Loupas

Publication number: 20230329670Abstract: An ultrasound system is used to measure the percent stenosis of a vessel in terms of residual lumen area. A measurement of volume blood flow is made at an unobstructed point of the vessel near the site of the stenosis. A measurement of the time averaged mean blood flow velocity is made at the stenosis. The quotient of these two values is computed to produce an estimate of the residual lumen area and the percent stenosis at site of the obstruction.Type: ApplicationFiled: June 21, 2023Publication date: October 19, 2023Inventor: James Robertson Jago

Publication number: 20230143880Abstract: An ultrasonic diagnostic imaging system is used to measure volume flow. An ultrasound probe operating in the biplane mode is used to acquire a vessel in a long axis view in a first Doppler image, and simultaneously in a transverse view in a second Doppler image. Volume flow is calculated from the transverse view of the vessel. The plane of the second image is aligned with the Doppler angle of the first image so that angle correction determined for the first image can be used for angle correction in the volume flow calculation.Type: ApplicationFiled: April 14, 2021Publication date: May 11, 2023Inventors: James Robertson Jago, Thanasis Loupas

Publication number: 20220183655Abstract: An ultrasonic diagnostic imaging system acquires volume image flow data sets of subvolumes of a blood vessel over at least a cardiac cycle. Image data of the subvolumes is then aligned both spatially and temporally to produce 3D images of the volume flow of the blood vessel over a heart cycle. A volume flow profile curve is produced from the acquired volume image flow data sets. The subvolumes are scanned starting with the center of the blood vessel and proceeding outward therefrom. The blood vessel center may be designated manually by a user or automatically by the ultrasound system by Doppler or other methods. Each subvolume is scanned over a heart cycle, with the systolic phase in the temporal center of the acquisition interval. The subvolumes are scanned in synchronism with the heart cycle and the estimation of a heart cycle is updated during each subvolume data acquisition interval.Type: ApplicationFiled: March 19, 2020Publication date: June 16, 2022Inventors: SHENG-WEN HUANG, JAMES ROBERTSON JAGO, SIBO LI, SHIYING WANG, JUN SOEB SHIN, GERARD JOSEPH HARRISON, THANASIS LOUPAS, LIANG ZHANG

Patent number: 11006923Abstract: An ultrasound system includes a 3D imaging probe and a needle guide which attaches to the probe for guidance of needle insertion into a volumetric region which can be scanned by the 3D imaging probe. The needle guide responds to the insertion of a needle through the guide by identifying a plane for scanning by the probe which is the insertion plane through which the needle will pass during insertion. The orientation of the insertion plane is communicated to the probe to cause the probe to scan the identified plane and produce images of the needle as it travels through the insertion plane.Type: GrantFiled: June 28, 2013Date of Patent: May 18, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Gary Lee Andrews, Vijay Parthasarathy, Gary Cheng-How Ng, Douglas Allen Stanton, Andrew Lee Robinson, Jochen Kruecker, Christopher Stephen Hall, James Robertson Jago, Vijay Shamdasani

Patent number: 10410409Abstract: An ultrasound system and method are described for acquiring standard views of the fetal heart simultaneously with real-time imaging. A matrix array probe is manipulated until a first standard view such as a 4-chamber view is acquired. The first standard view image is matched to its corresponding plane in a fetal heart model. From the matched plane of the heart model, the orientations of the other standard views are known from the geometrical relationships of structures within the heart model. This orientation information is used to control the matrix array probe to automatically scan the planes of all of the standard views simultaneously in real-time.Type: GrantFiled: July 26, 2017Date of Patent: September 10, 2019Assignee: Koninklijke Philips N.V.Inventors: James Robertson Jago, Alasdair Dow, Antoine Collet Billon, Lisa Kay Pumphrey

Patent number: 10368844Abstract: An ultrasound system with a matrix array (500) probe (10) operable in the biplane mode is used to assess stenosis of a blood vessel by simultaneously displaying two color Doppler biplane images (60a, 60b) of the vessel, one a longitudinal cross-sectional view (60a) and the other a transverse cross-sectional view (60b). The two image planes intersect along a Doppler beam line (68) used for PW Doppler. A sample volume graphic (SV) is positioned over the blood vessel at the peak velocity location in one image, then positioned over the blood vessel at the peak velocity location in the other image. As the sample volume location is moved in one image, the plane and/or sample volume location of the other image is adjusted correspondingly. Spectral Doppler data (62) is then acquired and displayed from the sample volume location.Type: GrantFiled: September 27, 2013Date of Patent: August 6, 2019Assignee: Koninklijke Philips N.V.Inventors: James Robertson Jago, Keith William Johnson, Ashraf Saad, David Allen Hull

Patent number: 10290076Abstract: A system and method for image registration includes tracking (508) a scanner probe in a position along a skin surface of a patient. Image planes corresponding to the position are acquired (510). A three-dimensional volume of a region of interest is reconstructed (512) from the image planes. A search of an image volume is initialized (514) to determine candidate images to register the image volume with the three-dimensional volume by employing pose information of the scanner probe during image plane acquisition, and physical constraints of a pose of the scanner probe. The image volume is registered (522) with the three-dimensional volume.Type: GrantFiled: March 2, 2012Date of Patent: May 14, 2019Assignees: The United States of America, as represented by the Secretary, Department of Health and Human Services, Koninklijke Philips N.V.Inventors: Samuel Kadoury, Jochen Kruecker, James Robertson Jago, Bradford Johns Wood, Antoine Collet-Billon, Cecile Dufour
