RiP #1: Title:   Comparison Study of Intraoperative Surface Acquisition Methods for Surgical Navigation via Tracked Intraoperative Ultrasound

RIP #1 Description: Soft-tissue image-guided interventions often require the digitization of organ surfaces for providing correspondence from medical images to the physical patient in the operating room, and the deformation of the organ represents a significant error source in current surgical navigation systems used for open hepatic procedures. However, clinical validation of the proposed methods, which rectifies the tissue deformation, has been limited to surface-based metrics, and subsurface validation has largely been performed via phantom experiments. In this talk I will present two surface digitization method involving the analysis of two registration approaches for open hepatic image-guided surgery systems via subsurface targets digitized with tracked intraoperative ultrasound (iUS).

Bowen Xiang received his BS in Biomedical Engineering from the University of Virginia in 2020 where he was researching genetically encoded fluorescent indicator for neurotransmitters under Dr. J.Julius Zhu. At Vanderbilt, he works with Dr. Miga in the Biomedical Modeling Lab to research localization methods of subsurface targets during liver surgery.

Speaker #2: Jared P. Lawson, PhD Candidate, Department of Mechanical Engineering

RiP #2: Towards Sensing and Control of Stroke Thrombectomy Microcatheters

RIP #2 Description:  Ischemic stroke from large vessel occlusions (LVO’s) is a leading cause of death and disability around the globe. While endovascular mechanical thrombectomy (MT) has been shown to significantly improve patient outcomes if performed <24hrs from stroke onset, the required catheter navigation techniques of this procedure demand highly skilled/trained interventionalists, which prohibits the widespread use of emergent MT. In this talk I will present our group’s work towards enabling semi-autonomous catheter navigation and enabling sensory augmentation for the MT procedure, which we hope will lower the skill barrier and improve access to this effective procedure.

Jared P. Lawson received his B.S. in Mechanical Engineering from Boston University in 2018, where he began to learn about and work with surgical robotics. After spending time working with surgical robotics in industry, he joined Dr. Nabil Simaan’s ARMA Lab where he focuses on steerable robotic catheters for neurointerventional surgery.
