Abstract
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.
