Doppler Blood Flow Detector
Content Overview
The Blood Flow Detector is primarily used during surgery to provide: navigational assistance, navigation replacement without external systems, and elimination of guesswork based on experience. It enables precise intraoperative vessel localization, replacing tactile sensation and optimistic estimation. As an A-mode ultrasound device, it utilizes the Doppler effect principle to perform real-time monitoring of blood flow within vessels.
