Abstract
The proposed method integrates an optical probe to detect blood and prevent internal bleeding during biopsy, by acquiring reflected signals to identify the presence of blood in real time. This approach is validated using a modulated peristaltic pump that simulates blood flow in an artificial vein. During testing, the phantom is illuminated while a spectrometer collects the reflected light. To enhance detection, a lock-in technique tracks heartbeat-related light variations. Results confirm reliable blood detection, using a biopsy-compatible probe and a prism that replicates the lateral aperture of a typical biopsy needle.
