Abstract:
The effects of subcooled boiling of water and blood in the experimental cuvette and rabbit hepatic vessels under the influence of optical fiber-guided continuous IR laser radiation (1.94 μm) were studied using optical methods and ultrasonic diagnostics near the tip of the laser optical fiber. The liver was chosen as a model of vascular abnormality with a conglomerate of blood vessels. In the proposed approach, modification (obliteration and coagulation) of the vascular anomalies occurred as a result of intense subcooled boiling of the blood with generation of heated submerged jets.
