Acoustic 3d tracking of interventional tool

A system, comprising:

• an interventional tool;
• and
• a plurality of acoustic sensors spatially aligned relative to the interventional tool,
• each of the plurality of acoustic sensors being structurally configured to output a composite acoustic sensing waveform derived from an acoustic sensing of an acoustic image plane, and
• wherein each composite acoustic sensing waveform includes an array of acoustic beam sensing waveforms.

A method for tracking an interventional tool based on a spatial alignment of at least two acoustic sensors relative to the interventional tool, the method comprising:

• operating an acoustic imaging device to generate an acoustic image plane;
• operating each acoustic sensor to output an composite acoustic sensing waveform derived from an acoustic sensing of the acoustic beam array,
• wherein each composite acoustic sensing waveform includes an array of acoustic beam sensing waveforms;
• and
• operating a tracking workstation to track a position of the interventional tool relative to the acoustic image plane derived from a waveform profile analysis of the composite acoustic sensing waveforms.
