Abstract
Ultrasound US) imaging is widely used for guiding percutaneous needle procedures, but accurate visualisation of the needle tip and patient anatomy in 3D and in real-time is challenging. We introduce a system that integrates 3D US imaging with a needle tip tracking modality for guiding minimally invasive procedures such as nerve blocks and tumour biopsies. Using a 256-element sparse spiral array for real-time 3D imaging, the system also provides precise 3D tracking information of the needle tip with an integrated fibreoptic US sensor (FOS) that communicates with the US imaging probe. FOS data were beamformed to generate an image of the needle tip, precisely pinpointing its location on the B-mode images. The tracking accuracy of the systems was tested in a water tank using a 3D translation stage. The accuracy in the vertical direction (Z, depth) was 0.32 mm ± 0.16 mm (RMSE ± SD). In the lateral and elevational directions, the accuracies were 1.21 mm ± 0.55 mm and 0.63 mm ± 0.15 mm, respectively. The clinical translational potential of the system was further demonstrated with needle insertions into ex vivo chicken tissue. Future development aims to enhance image quality and tracking speed, offering significant advancements in the efficiency and safety of needle-based interventions.
