Summary
This study presents an integrated optical coherence tomography (OCT) and laser microsurgery system for enhanced blood coagulation. The system uses continuous-wave laser diodes and an OCT-based algorithm for precise targeting and real-time monitoring during procedures.
Area of Science:
- Biomedical Engineering
- Medical Imaging
- Laser Microsurgery
Background:
- Inducing blood coagulation is challenging for patients with hemostasis dysfunction or during surgery.
- Current methods may lack precision and real-time monitoring capabilities.
Purpose of the Study:
- To develop an integrated system combining optical coherence tomography (OCT) and laser microsurgery for effective blood coagulation.
- To create an algorithm for precise treatment site localization using OCT imaging.
- To utilize continuous-wave laser diodes (CW-LDs) for efficient and controlled blood coagulation.
Main Methods:
- Integration of OCT for real-time 2D/3D imaging and angiography.
- Development of an imaging-based feedback algorithm for precise laser microsurgery positioning.
- Application of CW-LDs at 450 nm and 532 nm for enhanced hemoglobin absorption and coagulation.
Main Results:
- Accurate laser exposure positioning was achieved using the OCT-based feedback system.
- Efficient blood coagulation was successfully induced using CW-LDs.
- Real-time OCT monitoring allowed for effective observation of the coagulation process.
Conclusions:
- The integrated OCT and CW-LD laser microsurgery system offers precise targeting and real-time monitoring for blood coagulation.
- This technology has the potential to improve surgical outcomes by enabling controlled laser exposure and minimizing collateral damage.
