A Parametric Study of Flushing Conditions for Improvement of Angioscopy Visibility
Journal of Functional Biomaterials, 2022 During an angioscopy operation, a transparent liquid called dextran is sprayed out from a catheter to flush the blood away from the space between the camera and target. Medical doctors usually inject dextran at a constant flow rate.

Efficacy of Angioscopy for the Detection of Mobile Carotid Artery Lesions [PDF]
Stroke: Vascular and Interventional Neurology, 2023 Case presentation A 78‐year‐old man with a mobile lesion was diagnosed with thrombus using carotid ultrasonography, but the lesion was not completely resolved with dual antiplatelet and anticoagulation therapy. Direct visualization by angioscopy showed a

Catheter pose-dependent virtual angioscopy images visualized on augmented reality glasses
Current Directions in Biomedical Engineering, 2019 Fluoroscopy and digital subtraction angiography provide guidance in endovascular aortic repair (EVAR) but introduce radiation exposure and require the administration of contrast agent. To overcome these disadvantages, previous studies proposed to display
