High Bandwidth Acoustic Sensor Array For Laser Based Surgeries

Timeline

Status: Active

Description

Over the last few Laser scalpels have been explored as a minimally invasive method for soft tissue surgeries and tumor removal. While proven to be more precise, accurate, and versatile than traditional surgical tools, the technology has seen a suboptimal pace of adoption due to a lack of intuitive sensory feedback. 

The project stems from an ongoing research project in the Brain Tools Laboratory that attempts to bridge this sensory gap. The overarching project seeks to create a flexible, non-nvasive sensor array with that extrapolates the tissue type and laser position from the acoustic signals generated during laser surgeries. 

Our work with the Innovation Co-Lab will focus on the development of a functional rigid acoustic sensor array prototype as a demonstration of feasibility for one of the core goals: using piezoelectric transducers for localization across the bandwidth of acoustic signals generated during laser ablation (20 KHz – 500 KHz).

Additional project deliverables will include a test fixture for localization validation, featuring a 2 axis linear stage with a sound generation source.
