N2 - Image-guided surgery is today considered to be ofsignificant importance in neurosurgical applications.However, oneof its major shortcomings is its reliance on preoperative imagedata, which does not account for brain deformations and displacementsthat occur during surgery. In this work, we propose totackle this issue through the incorporation of an ultrasound devicewithin the type of biopsy needles commonly used as an interventionaltool to provide immediate feedback to neurosurgeonsduring surgical procedures. To identify the most appropriate pathto access a targeted tissue site, single-element transducers thatlook either forward or sideways have been designed and fabricated.Micromolded 1–3 piezocomposites were adopted as theactive materials for feasibility tests and epoxy lenses have beenapplied to focus the ultrasound beam. Electrical impedance analysis,pulse-echo testing, and wire phantom scanning have been carriedout, demonstrating the functionality of the needle transducersat ∼16 MHz. The capabilities of these transducers for intraoperativeimage guidance were demonstrated by imaging withinsoft-embalmed cadaveric human brain and fresh porcine brain.
