  • Publication number: 20240320834
    Abstract: A method (100) is disclosed for determining a signal indicative of a state of a subject during a diagnostic imaging or therapeutic procedure based on camera observation. The method comprises acquiring (101) camera images from a camera configured to monitor a body part of the subject during the procedure, e.g. via a reflection thereof in a reflective surface. The method comprises detecting (102) a shape or contour of the reflective surface in at least one acquired camera image to define a region of interest in the image that contains image information corresponding to the body part of interest, and segmenting (103) the region of interest in one or more camera images to select pixels that correspond to a feature of the body part of interest. The method also comprises determining (105) the signal indicative of the state of the subject from the selection. The invention further relates to a corresponding device, system and computer-program.

  • Patent number: 11751952
    Abstract: A medical sensing system (100) includes an elongate interventional device (101) and an adjustable capacitance circuit (102). The elongate interventional device (101) includes a sensor (103) having a capacitance (Css). The elongate interventional device (101) also includes a first electrical conductor (104) and a second electrical conductor (105). The first electrical conductor (104) and the second electrical conductor (105) are in electrical contact with the sensor (103) and extend along the elongate interventional device (101). The elongate interventional device (101) also includes i) an electrically conductive shield (106) that overlaps the electrical conductors (104, 105) and/or ii) an electrically conductive shaft (107).
