Publication number: 20240050163Abstract: A mechanism for adjusting the direction of one or more crossing electric fields that have been induced by a set of electrodes positioned on a patient, without necessitating movement of any of the electrodes. This is achieved through the use of one or more electrode patches, which effectively allow an electric field generator to control a position of a source/sink of an electric field, to thereby control a direction of the electric field.Type: ApplicationFiled: December 31, 2021Publication date: February 15, 2024Inventors: Gerardus Henricus Maria GIJSBERS, Rogier Rudolf WILDEBOER, Matthijs Joseph Maria CLUITMANS, Alexander Franciscus KOLEN, Walter RUETTEN, Josephus Arnoldus Johannes Maria KAHLMAN

Patent number: 11839509Abstract: The present invention relates to an ultrasound system. A first non-invasive ultrasound probe receives first ultrasound data having a first field of view and a second invasive ultrasound probe receives second ultrasound data having a second field of view which is different from the first field of view. A tracking unit determines tracking data including a position and orientation of the first non-invasive ultrasound probe relative to the second invasive ultrasound probe. A registration unit registers the second field of view into the first field of view based on the tracking data.Type: GrantFiled: June 1, 2018Date of Patent: December 12, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Gerardus Henricus Maria Gijsbers, Alexander Franciscus Kolen, Harm Jan Willem Belt, Nenad Mihajlovic, Jean-Luc Francois-Marie Robert

Publication number: 20230355213Abstract: An ultrasound image processing apparatus includes an image processor arrangement that receives a plurality of ultrasound images. Each ultrasound image shows an invasive medical device relative to an anatomical feature during a cardiac cycle. At different phases of the cardiac cycle, the anatomical feature has a different shape. The ultrasound processing apparatus compiles groups of the ultrasound images with ultrasound images in each group belonging to the same phase of the cardiac cycle. The ultrasound image processing apparatus generates an augmented ultrasound image from one of the ultrasound images by removing a shadow region on the anatomical feature of interest caused by the invasive medical device based on a displacement of the invasive medical device.Type: ApplicationFiled: July 7, 2023Publication date: November 9, 2023Inventors: Alexander Franciscus Kolen, Harm Jan Willem Belt, Godefridus Antonius Harks, Geert Gerardus Henricus Maria Gijsbers, Hong Liu

Publication number: 20230334679Abstract: A mechanism for registering ultrasound images with an anatomical map generated using a dielectric imaging process. The positions of electrodes that move with the ultrasound probe are monitored using the same dielectric imaging system that generated the anatomical map. The position at which ultrasound images are generated is captured, and this information is used to register the ultrasound image(s) with respect to the anatomical map.Type: ApplicationFiled: September 7, 2021Publication date: October 19, 2023Inventors: Alexander Franciscus KOLEN, Martinus Bernardus VAN DER MARK, Gerardus Henricus Maria GIJSBERS, Godefridus Antonius HARKS

Patent number: 11759176Abstract: A method for ultrasound image processing having steps of receiving sequences of ultrasound images imaging an anatomical feature of interest during two cardiac cycles one in the absence of, and the other in the presence of, an invasive medical device in said ultrasound images, each ultrasound image corresponding to a different phase of said cardiac cycle. The invasive medical device may at least partially obscure the anatomical feature of interest for each ultrasound image of the further sequence. The location of the invasive medical device is tracked and isolated in the ultrasound image, and the isolated invasive medical device is inserted into an ultrasound image of the first sequence of a corresponding phase of the cardiac cycle in the tracked location. The method also controls a display device to display the first sequence of ultrasound images including the inserted invasive medical device.Type: GrantFiled: November 24, 2021Date of Patent: September 19, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Alexander Franciscus Kolen, Harm Jan Willem Belt, Godefridus Antonius Harks, Gerardus Henricus Maria Gijsbers, Hong Liu

Publication number: 20230157614Abstract: A system (10) is for performing ECG measurements and comprises a probe (12) with an integrated one or more ECG electrodes (22) and an ultrasound sensing means (18), such as a transducer arrangement. The probe thus provides a mobile ECG electrode which can be sequentially moved between a set of different locations on the body for acquiring ECG measurements from different angles relative to the heart (i.e. different ‘leads’). Positioning of the probe in each required location is guided by a position guidance function which uses ultrasound data acquired by the ultrasound sensing means to locate the probe (with reference to an ultrasound body atlas (28) or map), and uses a stored set of reference body locations to guide a user with guidance information as to how to move the probe to arrive at a next target electrode location. In examples, the user may be guided through a sequence of electrode locations, with ECG data acquired at each one, thereby sequentially building up a set of standard ECG lead measurements.Type: ApplicationFiled: March 31, 2021Publication date: May 25, 2023Inventors: Robertus Leonardus Maria in 't Groen, Gerardus Henricus Maria Gijsbers, Fei Zuo, Mark Johnson, Biswaroop Chakrabarti, Sujitkumar Hiwale, Deep Bera
