The present invention relates to a system for indicating a position of an interventional device feature () of an interventional device () respective an image plane () defined by an ultrasound imaging probe () of a beamforming ultrasound imaging system () in which the position of the interventional device feature () is determined based on ultrasound signals transmitted between the ultrasound imaging probe () and an ultrasound transducer () attached to the interventional device at a predetermined distance (Lp) from the interventional device feature (). 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.

Tracking a feature of an interventional device

System () for determining a position of an interventional device () respective an image plane () defined by an ultrasound imaging probe (). The position is determined based on ultrasound signals transmitted between the ultrasound imaging probe () and an ultrasound transducer () attached to the interventional device (). An image reconstruction unit (IRU) provides a reconstructed ultrasound image (RUI). A position determination unit (PDU) computes a lateral position (LAP) of the ultrasound transducer () respective the image plane () based on a time of flight (TOF) of a maximum detected intensity (I) ultrasound signal. The position determination unit (PDU) also computes an out-of-plane distance (D) between the ultrasound transducer () and the image plane (). Computing the out-of-plane distance (D) involves comparing the maximum detected intensity (I) with a model (MO) describing an expected variation of in-plane maximum detected intensity (I) with time of flight.

Tracking an interventional device within an ultrasound image plane

System () for determining a position of an interventional device () respective an image plane () defined by an ultrasound imaging probe (). The position is determined based on ultrasound signals transmitted between the ultrasound imaging probe () and an ultrasound transducer () attached to the interventional device (). An image reconstruction unit (IRU) provides a reconstructed ultrasound image (RUI). A position determination unit (PDU) computes a position (LAP) of the ultrasound transducer () respective the image plane (). The position determination unit (PDU) indicates the computed position (LAP) in the reconstructed ultrasound image (RUI). The position determination unit (PDU) suppresses the indication of the computed position (LAP) under specified conditions relating to the computed position (LAP) and the ultrasound signals.

Interventional device positioning relative to an ultrasound image plane

An interventional device includes an elongate shaft () with a longitudinal axis (A-A'), and an ultrasound detector (). The ultrasound detector () comprises a PVDF homopolymer foil strip (). The foil strip () is wrapped around the longitudinal axis (A-A&#x2032;) of the elongate shaft () to provide a band having an axial length (L) along the longitudinal axis (A-A&#x2032;). The axial length (L) is in the range 80-120 microns.

Interventional device with PVDF ultrasound detector

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. The frame is adapted for attachment to an ultrasound imaging probe. The position triangulation unit determines a spatial position of the ultrasound detector relative to the at least three ultrasound emitters based on signals received from an ultrasound detector that is attached to the medical device. The frame includes a detachable reference volume comprising a background volume and an inclusion or void. When the detachable reference volume is attached to the frame and the frame is attached to the ultrasound imaging probe the inclusion or void provides a corresponding image feature within the field of view of the ultrasound imaging probe for use in calibrating the field of view of the ultrasound imaging probe with the coordinate system of the localization system.

Ultrasound based tracking

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.
