Publication number: 20220000580Abstract: The invention relates to an active marker device (100) for being introduced into a human tissue and for tracking a region of interest of a human body. The active marker device comprises a light source (101) for emitting light such that the emitted light can be detected by an optical sensor. In this way, the active marker device and/or the region of interest can be tracked by a tracking system comprising the optical sensor. The active marker device (100) further comprises a switch (102) for turning the light source on and off and for operating the light source in a pulsed mode.Type: ApplicationFiled: September 17, 2021Publication date: January 6, 2022Inventors: BERNARDUS HENDRIKUS WILHELMUS HENDRIKS, MICHAEL GRASS, THOMAS KOEHLER, HAROLD AGNES WILHELMUS SCHMEITZ, ROLAND PROKSA, VISHNU VARDHAN PULLY, MARCO ANDREAS JACOBUS VAN AS, WALTHERUS CORNELIS JOZEF BIERHOFF, FRANCISCUS MARINUS ANTONIUS MARIA VAN GAAL, DRAZENKO BABIC

Patent number: 11154199Abstract: A medical imaging system for identifying a target structure (TS), e.g. a tumor, in a biological tissue. A hyperspectral camera system is used for imaging a surface area (A1) of the tissue (BT), e.g. with a limited spectral resolution, but enough to allow identification of suspicious areas where the target structure (TS) may be, e.g. such areas can be visually indicated on a display to the operator. A probe (PR), e.g. an optical surface probe, is used to provide probe measurement of a smaller surface area (A2) of the tissue, but with more information indicative of the target structure. The probe is selected to provide a higher specificity with respect to identification of the target structure than the hyperspectral camera (HSC). The hyperspectral processing algorithm (PP) is then calibrated based on probe measurement data performed within the suspicious areas, thus providing a calibrated hyperspectral processing algorithm resulting in images with an enhanced sensitivity to identify the target structure.Type: GrantFiled: January 22, 2014Date of Patent: October 26, 2021Assignee: Koninklijke Philips N.V.Inventors: Bernardus Hendrikus Wilhelmus Hendriks, Johannes Joseph Hubertina Barbara Schleipen, Christian Reich, Gerhardus Eilhelmus Lucassen, Manfred Mueller, Vishnu Vardhan Pully

Patent number: 10531921Abstract: The present invention relates to a method for determining a state of tissue sealing during a tissue sealing process. According to the disclosed method, an optical probe beam is used to irradiate a tissue region. A signal indicative of optical scattering in the tissue region is generated from a portion of the optical probe beam that has passed through or been returned by the tissue region. The onset of tissue sealing is indicated by the successive occurrence in time of a turning point and a point of inflection in the optical scattering signal. An energy-based tissue sealing or tissue-cutting device for use in accordance with the method is also disclosed.Type: GrantFiled: July 14, 2015Date of Patent: January 14, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Bernardus Hendrikus Wilhelmus Hendriks, Torre Michelle Bydlon, Vishnu Vardhan Pully, Charles Frederik Sio, Sandra Martina Van Den Bosch, Gerhardus Wilhelmus Lucassen

Patent number: 10299684Abstract: A system and method to support exploring the interior of an object. The system 100, 200 includes a graphical user interface generator (GG) to generate a graphical user interface (GUI). The graphical user interface (GUI) includes an indicator (NC) of a current position of an interventional tool (IT) inside an object (OB). There is also an exploratory indictor (PC) to indicate material composition and/or type that surrounds the tool's tip (TP) at a current position in the object (OB). The exploratory indicator (PC) includes a pointer element for a current reading against a dial element for a range of possible values.Type: GrantFiled: December 17, 2014Date of Patent: May 28, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Bernardus Hendrikus Wilhelmus Hendriks, Torre Michelle Bydlon, Arnoldus Theodorus Martinus Hendricus Van Keersop, Gerhardus Wilhelmus Lucassen, Vijay Parthasarathy, Vishnu Vardhan Pully, Marjolein Van Der Voort, Manfred Mueller, Gerardus Henricus Maria Gijsbers

Patent number: 9867599Abstract: An interventional device, e.g. a Vacuum Assisted Biopsy (VAB) needle, incorporating optical fibers such that biological tissue in a volume at a side of the interventional device can be substantially completely optically probed by optical spectroscopy. In a VAB embodiment, a plurality of optical fiber pairs connected to respective optical ports, are placed at opposite positions along the suction cavity, and they are readout subsequently allowing to make a map of the tissue properties along the place where the tissue will be cut by the VAB needle. Based on decision software in an optical console, it can be determined whether the tissue present in the cutting cavity is completely normal tissue or not, prior to actually performing the biopsy on the tissue. In this way a well defined end point for VAB is created.Type: GrantFiled: October 16, 2013Date of Patent: January 16, 2018Assignee: Koninklijke Philips N.V.Inventors: Bernardus Hendrikus Wilhelmus Hendriks, Christian Reich, Waltherus Cornelis Jozef Bierhoff, Manfred Mueller, Franciscus Marinus Antonius Maria Van Gaal, Jozef Christiaan Mathieu Versleegers, Vishnu Vardhan Pully, Sven Stoffelen
