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 position (LAPTOFSmax, ?IPA) of the ultrasound transducer (15) respective the image plane (12). The position determination unit (PDU) indicates the computed position (LAPTOFSmax, ?IPA) in the reconstructed ultrasound image (RUI). The position determination unit (PDU) suppresses the indication of the computed position (LAPTOFSmax, ?IPA) under specified conditions relating to the computed position (LAPTOFSmax, ?IPA) and the ultrasound signals.

Abstract: An interventional device includes an elongate shaft (101) with a longitudinal axis (A-A?), and an ultrasound detector (102). The ultrasound detector (102) comprises a PVDF homopolymer foil strip (103). The foil strip (103) is wrapped around the longitudinal axis (A-A?) of the elongate shaft (101) to provide a band having an axial length (L) along the longitudinal axis (A-A?). The axial length (L) is in the range 80-120 microns.

Abstract: The present invention relates to an ultrasound-based system for localizing a medical device within the field of view of an ultrasound imaging probe. A localization system is provided that includes at least three ultrasound emitters that are arranged on a frame; and a position triangulation unit.

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.
