Update on Intravascular Ultrasound
Journal of Interventional Cardiology, 1998 Intravascular ultrasound (IVUS) has moved from being predominately a research tool at tertiary interventional centers to a clinical instrument used routinely to assess interventional success and resolve diagnostic challenges. Advances in instrumentation technology, along with emerging clinical data, have contributed to the wider application of IVUS ...

Geo-UNet: A Geometrically Constrained Neural Framework for Clinical-Grade Lumen Segmentation in Intravascular Ultrasound [PDF]
arXivPrecisely estimating lumen boundaries in intravascular ultrasound (IVUS) is needed for sizing interventional stents to treat deep vein thrombosis (DVT). Unfortunately, current segmentation networks like the UNet lack the precision needed for clinical adoption in IVUS workflows.

Classifier-guided registration of coronary CT angiography and intravascular ultrasound [PDF]
arXivCoronary CT angiography (CCTA) and intravascular ultrasound (IVUS) provide complementary information for coronary artery disease assessment, making their registration valuable for comprehensive analysis. However, existing registration methods require manual interaction or extensive segmentations, limiting their practical application.

Bifurcation Identification for Ultrasound-driven Robotic Cannulation [PDF]
IEEE/RSJ International Conference on Intelligent Robots and
Systems (IROS) 2024In trauma and critical care settings, rapid and precise intravascular access is key to patients' survival. Our research aims at ensuring this access, even when skilled medical personnel are not readily available. Vessel bifurcations are anatomical landmarks that can guide the safe placement of catheters or needles during medical procedures.
