A device (e.g., a valve) can be visualized in a patients body (e.g., in the patients heart) using an ultrasound system with added position sensors. One position sensor is mounted in the ultrasound probe, and another position sensor is mounted in the device installation apparatus. The devices position with respect to the imaging plane is determined based on the detected positions of the position sensors and known geometric relationships. A representation of the device and the imaging plane, as viewed from a first perspective, is displayed. The perspective is varied to a second perspective, and a representation of the device and the imaging plane, as viewed from the second perspective, is displayed. Displaying the device and the imaging plane from different perspectives helps the user visualize where the device is with respect to the relevant anatomy.
