Multimodal Optical Imaging and Modulation with Simultaneous Electrophysiology Through Smart Dura in Non‐Human Primates

open access: yesAdvanced Science, EarlyView.
This study demonstrates multimodal integration in non‐human primates, combining large‐scale, high‐density electrophysiology using Smart Dura with optical techniques such as multiphoton imaging (MPI), photothrombotic lesioning, optical coherence tomography angiography (OCTA), wide‐field intrinsic signal optical imaging (ISOI), and optogenetics.

Using Hydrogel Beads as a Blood Model in Optical Coherence Tomography

open access: yesCurrent Directions in Biomedical Engineering, 2023
Optical Coherence Tomography (OCT) is a standard imaging procedure in ophthalmology. OCT Angiography is a promising extension, allowing for fast and non-invasive imaging of the retinal vasculature analyzing multiple OCT scans at the same place.

Outcomes of optical coherence tomography guided percutaneous coronary intervention against angiography guided in patients with coronary artery disease: A systematic reviews and meta-analyses

open access: yesIndian Heart Journal, 2023
Background: Previous studies compared optical coherence tomography (OCT) guided percutaneous coronary intervention (PCI) and angiography-guided was still limited. Therefore, we performed comprehensive meta-analyses to investigate the clinical outcomes of

Ergonomic handheld OCT angiography probe optimized for pediatric and supine imaging.

open access: yesBiomedical Optics Express, 2019
OCT angiography is a functional extension of OCT that allows for non-invasive imaging of retinal microvasculature. However, most current OCT angiography systems are tabletop systems that are typically used for imaging compliant, seated subjects.

Bio‐Inspired Micro‐Fin‐Assisted Multi‐Modal Vascular Intervention

open access: yesAdvanced Science, EarlyView.
A magnetic guidewire with a micro‐fin–integrated tip is introduced for multimodal cardiovascular navigation. The micro‐fins exploit fluid drag to augment magnetic torque, enabling bifurcation traversal at 15 mT, tolerating 45° misalignment, bidirectional crawling, and buckle self‐correction.
