Eversion-based robots can enable safe access,steering and endoscopic imaging within the spinal subarachnoid space
Zicong Wu, Panagiotis Kalozoumis, S. M. Hadi Sadati +8
Safe navigation within the spinal subarachnoid space is constrained by its narrow, compliant, and delicate anatomy. Conventional catheters and continuum robots rely on proximal pus…
Real-time 3D Ultrasonic Needle Tracking with a Photoacoustic Beacon
Christian Baker, Weidong Liang, Richard Colchester +7
Many minimally invasive procedures, such as core needle biopsy of focal liver lesions, nerve blocks, and fetal and vascular interventions, are typically performed under ultrasound…
Three-dimensional intraoperative light field fluorescence imaging system for PpIX-guided tumour resection
Yucheng Bian, Sebastien Ourselin, Yijing Xie
Conventional 2D fluorescence imaging in glioma surgery cannot separate intrinsic fluorophore strength from attenuation with depth, creating depth-intensity ambiguity that can compr…
Volumetric ultrasound imaging with a sparse matrix array and integrated fiber-optic sensing for robust needle tracking in interventional procedures
Weidong Liang, Javad Rostami, Christian Baker +7
Accurate visualization of interventional devices, such as medical needles, is essential for the safe and effective guidance of minimally invasive procedures. Ultrasound (US) imagin…
Light Focusing through Dynamic Media via Real-Valued Intensity Transmission Matrix
Xuan Liu, Sebastien Ourselin, Tianrui Zhao
Precise light delivery through biological tissue is essential for deep-tissue imaging and phototherapeutic applications. Wavefront shaping enables control over scattered light by m…
A Fully Open and Generalizable Foundation Model for Ultrasound Clinical Applications
Hongyuan Zhang, Yuheng Wu, Mingyang Zhao +22
Artificial intelligence (AI) that can effectively learn ultrasound representations by integrating multi-source data holds significant promise for advancing clinical care. However,…
