Publication number: 20220096162Abstract: The invention relates to assisting a user in moving an insertion element within an object. A three-dimensional (3D) position and 3D local shape of the insertion element are tracked within the object. Based on the tracked 3D position and 3D local shape of the insertion element, an insertion element representation (42??) representing the insertion element within the object in its 3D position and 3D local shape is generated. Furthermore at least two different markings (78) applied along the length of the insertion element representation (42??) representing indications of the local shape of the insertion element are provided. A display image (60?) including the insertion element representation (42??) with the different markings (78) is displayed. Markings can for example include alternating ring-like structures (78) with alternating lighter and darker colors and/or different colors for the tip and the rest of the insertion element representation for improving 3D visualization of insertion elements.Type: ApplicationFiled: January 17, 2020Publication date: March 31, 2022Inventors: Roland Wilhelmus Maria BULLENS, Wilhelmus Henrica Gerarda Maria VAN DEN BOOMEN

Patent number: 11134917Abstract: Disclosed are an imaging system (10) or an interventional tool, such as a catheter (20), having a first ultrasound transducer array (23) and a second ultrasound transducer array (21) spaced by a fixed distance (D) from each other; wherein both arrays may be used to generate diagnostic images; and a processing arrangement (31, 32) to process a first sensor signal indicative of the first array imaging a reference location (X) at a first point in time, and to process a second sensor signal indicative of the second array imaging the reference location at a second point in time; and determine a translation (pullback) speed of the catheter from the set distance and the difference between the first point in time and the second point in time. Alternatively, a catheter may be provided comprising an ultrasound transducer array at a distal end of the catheter, and two pressure sensors for determining the translation speed.Type: GrantFiled: December 1, 2016Date of Patent: October 5, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Vincent Adrianus Henneken, Antonia Cornelia Van Rens, Roland Wilhelmus Maria Bullens, Arjen Van Der Horst, Ke Wang, Frank Michael Weber, Irina Waechter-Stehle

Patent number: 11031136Abstract: The invention relates to an assistance device, an assistance system and an assistance method for assisting a practitioner in an interventional hemodynamic (e.g fractional flow reserve (FFR)) measurement on a subject. The FFR pressure measurements are combined with an, for example, angiography-based assessment of the coronary vessel geometry. An advanced computational fluid dynamics model may be employed to add flow and myocardial resistance data based on the interventional pressure values and on a vascular model generated prior to the intervention. In case that these data are available prior to the intervention, the location of most optimal positions for pressure measurements can be pre-calculated and by overlay of the vessel tree, for example, on the X-ray projection, advice can be given for the interventional cardiologist during the intervention.Type: GrantFiled: July 26, 2016Date of Patent: June 8, 2021Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Michael Grass, Christian Haase, Peter Maria Johannes Rongen, Roland Wilhelmus Maria Bullens, Arjen Van Der Horst

Publication number: 20190069783Abstract: Devices, systems, and methods for evaluating a physiological condition of a vessel are disclosed. In an embodiment, a medical system is disclosed. One embodiment of the medical system comprises a medical processing unit in communication with a first pressure sensor, a second pressure sensor, and a radiographic imaging source configured to obtain radiographic images of at least one intravascular instrument positioned within a body lumen. The medical processing unit is configured to: receive the radiographic images obtained by the radiographic imaging source; detect, using the radiographic images, when the first pressure sensor is in a pre-determined orientation with respect to the second pressure sensor; and automatically initiate normalization of the first pressure sensor and the second pressure sensor in response to detecting that the first pressure sensor is in the pre-determined orientation with respect to the second pressure sensor.Type: ApplicationFiled: September 7, 2018Publication date: March 7, 2019Inventors: Roland Wilhelmus Maria BULLENS, Markus Johannes Harmen DEN HARTOG, Javier OLIVAN BESCOS, Willem-Jan SPOEL, Martijn Anne VAN LAVIEREN, Thijs ELENBAAS
