  • Patent number: 12004899
    Abstract: The present invention relates to a system for indicating a position of an interventional device feature (11a) of an interventional device (11) respective an image plane (12) defined by an ultrasound imaging probe (18) of a beamforming ultrasound imaging system (15) in which the position of the interventional device feature (11a) is determined based on ultrasound signals transmitted between the ultrasound imaging probe (18) and an ultrasound transducer (16) attached to the interventional device at a predetermined distance (Lp) from the interventional device feature (11a). An icon providing unit (IPU) provides a first icon (Cde) indicative of a circular zone with a radius corresponding to the predetermined distance (Lp). The first icon (Cde) is displayed in a fused image that includes a reconstructed ultrasound image (RUI) from the beamforming ultrasound imaging system.

  • Patent number: 11986339
    Abstract: System (10) for determining a position of an interventional device (11) respective an image plane (12) defined by an ultrasound imaging probe (13). The position is determined based on ultrasound signals transmitted between the ultrasound imaging probe (13) and an ultrasound transducer (15) attached to the interventional device (11). An image reconstruction unit (IRU) provides a reconstructed ultrasound image (RUI). A position determination unit (PDU) computes a lateral position (LAPTOFSmax, ?IPA) of the ultrasound transducer (15) respective the image plane (12) based on a time of flight (TOFSmax) of a maximum detected intensity (ISmax) ultrasound signal. The position determination unit (PDU) also computes an out-of-plane distance (Dop) between the ultrasound transducer (15) and the image plane (12).

  • Patent number: 10405761
    Abstract: One or more sensors and/or sensing techniques are used individually or in combination to detect and/or measure heart rate and/or heart rate variability. The sensors may be wearable and/or portable and may operate on different principles and may include different power profiles. The sensors and/or sensing techniques may be used at the same time or at different times that may overlap partially or completely, or may be mutually exclusive. A controller may select one or more sensors and/or sensing techniques based on operating conditions and/or based on conservation of power.

    Abstract: The present invention relates to a device for skin conductance measurement in a frequency range up to at least 50 Hz. The proposed device comprises two measurement terminals (23, 24) for applying a constant DC voltage to a skin area, a first measurement path (27) coupled between a first of said measurement terminals (23) and a first output terminal (25), a second measurement path (28) coupled between the second measurement terminals (24) and a second output terminal (26), two output terminals (25, 26) each providing a respective measurement voltage, the difference of which being related to the skin conductance of said skin area. This provide for cancelation of noise when measuring the difference at the output terminals.
