Mechanically, Thermally, and Geometrically-Tuned
Phantom Models for Laser Ablation Experiment
08/2022 - Present
Phantom models, or anatomically accurate models of human organs for surgical robotics testing, are an integral component for accurate surgical robotics workspace analysis testing and evaluation. I am exploring gel-based phantom models that can be mechanically and thermally tuned to mimic the properties of brain tissue. By doing so, we can conduct pseudo-realistic experiments on how CO2 cutting lasers interact with "brain tissue".
Sample Phantom Model
To compare and validate the mechanical and thermal properties of the phantom model to literature values on brain tissue, we need to conduct tests to obtain values that can be used to represent the mentioned properties. Indentation testing carried out on the phantom models to obtain the stress-strain curve to measure and calculate the Young's Modulus of these soft phantom models. The thermal conductivity of the phantoms will also be measured and calculated through steady-state heat flux experimentation.
