Abstract
While the use of tissue-mimicking (TM) phantoms has been ubiquitous in surgical robotics, the translation of technology from laboratory experiments to equivalent intraoperative tissue conditions has been a challenge. The increasing use of lasers for surgical tumor resection has introduced the need to develop a modular, low-cost, functionally relevant TM phantom to model the complex laser-tissue interaction. In this paper, a TM phantom with mechanically and thermally similar properties as human brain tissue suited for photoablation studies and subsequent visualization is developed. The proposed study demonstrates the tuned phantom response to laser ablation for fixed laser power, time, and angle. Additionally, the ablated crater profile is visualized using optical coherence tomography (OCT), enabling high-resolution surface profile generation.

Siobhan Oca's research focusses on medical robotics and robotics education. Specifically, she is interested in developing safe and effective autonomous medical procedures. Her doctoral research focussed on development of autonomous ultrasound scanning with robotic arm, implemented in a human study, which also assessed trust and safety. Since starting as faculty, she studies the methods used in teaching robotics to understand their efficacy in student learning and perception of robotics as a future career field.
She leads the Masters programs in Robotics for MEMS and is passionate about robotics curricula development that prepares students for their future in robotics and impacts on society, including through her Case Studies of Ethics in Robotics and Autonomy course.
