Abstract
An acoustic imaging apparatus and method receive a sensor signal from a passive sensor disposed on a surface of an intervention device which is disposed in an area of interest, wherein the passive sensor is located at a fixed distance from the tip of the intervention device. A processor is configured to ascertain an estimated range of locations of the tip of the intervention device in an image plane by using the sensor signal and an estimated effective distance, projected onto the image plane, from the passive sensor to the tip of the intervention device.
