Abstract
A system (200) performs a medical procedure in a region of interest of a patient. The system includes an interventional medical device (214) insertable into the region of interest, and a sensor (215) attached to a portion of the interventional device, the sensor being configured to convert an ultrasonic wave from an ultrasound imaging probe (211) to a corresponding electrical radio frequency (RF) signal. The corresponding RF signal is received by a wireless receiver (209) outside the region of interest, enabling determination of a location of the sensor within the region of interest.
