| Description: |
Objective. Ultrasound is commonly used to guide minimally invasive procedures; however, these are often hindered by poor needle-tip visibility. This work aims to develop a multilateration-based needle tracking system that is significantly faster than our previous one approach. Approach. The proposed system integrates a fiber-optic hydrophone within a medical needle to receive ultrasound transmissions from a sparse 2D matrix array probe, used for 3D imaging. Chirped excitation was employed to improve the signal-to-noise ratio and enable robust time-of-arrival estimation required for multilateration-based 3D localization. Main results. The system achieved spatial tracking accuracy of 2.49 ± 0.95 mm using only 13 active elements, representing an order-of-magnitude increase in tracking speed from 3.77 to 45.45 Hz compared to the previously used delay-and-sum-based tracking algorithm. 3D imaging and accurate needle-tip localization were demonstrated with ex vivo chicken tissue and a clinically realistic femoral nerve block phantom. Significance. These results demonstrate the feasibility of the system that combines 3D imaging and accurate needle tracking, showing strong potential to improve the precision and safety of ultrasound-guided interventions. |
