The OrthoJet project aims to develop an innovative medical water jet ablation method and tool for efficient, bone-friendly, and patient-friendly prosthesis loosening and bone cement removal. The goal is to pioneer an ablation instrument using pulsed fluid jet technology. The tool will be investigated to determine feature vectors for classification, and implement algorithms for sensor data preprocessing, potentially including signal processing techniques on Cyber-Physical Systems (CPS) and deep learning models to distinguish between material properties.
