2014-04-24Following robotic assisted laparoscopic prostatectomy (RALP), surgical margins are assessed for presence of cancerous tissues. An EIS/EIT based approach to identify benign and malignant tissues was evaluated. Excised prostates were probed using a micro-endoscopic EIT probe, and impedance measurements corresponding to benign and tumorous regions are compared.
2014-04-24We describe a simulation study evaluating different electrode configuration for a microendoscopic EIT probe intended to intraoperatively assess surgical margins during radical prostatectomy. In our simulation study, we analyze the performances of three probe designs with varying number of electrodes (8, 9, and 17) and configurations (dependent on number of electrodes).
