1. A system, comprising:
an acoustic probe having an array of acoustic transducer elements; and
an acoustic imaging instrument connected to the acoustic probe, the acoustic imaging instrument comprising:
a processor configured to:
provide transmit signals to at least one of the acoustic transducer elements to cause the array of acoustic transducer elements to transmit an acoustic probe signal to an area of interest,
produce acoustic images of an image plane of the area of interest in response to acoustic echoes received from the area of interest in response to the acoustic probe signal,
receive a sensor signal from a sensor disposed on a surface of an intervention device disposed in the area of interest, wherein the sensor signal is produced in response to the acoustic probe signal, and wherein the sensor is located at a fixed distance from a tip of the intervention device,
estimate a location of the sensor from the sensor signal,
estimate an angular orientation of the intervention device with respect to the image plane, and
estimate a range of locations of the tip of the intervention device in the image plane based on the estimated location of the sensor, the estimated angular orientation of the intervention device with respect to the image plane, and the fixed distance from the sensor to the tip of the intervention device; and
a display device configured to display (i) the acoustic images of the image plane in the area of interest and (ii) one or more markers on the acoustic images to indicate the estimated range of locations of the tip of the intervention device in the image plane.
