About

Karthik Krishnan is a researcher whose work focuses on the intersection of robotics and medical interventions, particularly in the domain of nonholonomic needle steering. His key contributions center on enhancing the precision of needle placement in clinical procedures such as biopsy, anesthesia, and cholangiography. Krishnan’s research addresses the challenge of using small-diameter needles, which are preferred for minimizing patient trauma but are notoriously difficult to steer accurately. His notable work, "Evaluation of nonholonomic needle steering using a robotic needle driver" (2010), explores the use of a robotic system to control needle trajectory, improving placement accuracy in soft tissues. While this paper has garnered 2 citations, it represents a foundational step in the development of robotic-assisted needle steering technologies. Krishnan’s contributions are significant for advancing minimally invasive procedures, where precision is critical for diagnostic and therapeutic outcomes. His work has implications for reducing procedural errors and improving patient safety, making him a notable figure in the field of medical robotics.
