A New Theoretical Model and Direct Experimental Verification of Thermal Equilibrium in Countercurrent Microvessels

摘要许丽莎9523082将从理论和实验两方面研究血管与周围组织之间的热传递。这项工作的重点是直径在80到200微米之间的一对匹配的血管，其模型将是体外培养的大鼠斜方肌。实验方法包括组织制备的红外成像和血流的多普勒测速。现有的分析模型将被评估和扩展以支持实验结果。应用包括组织冷冻、低温保存、激光手术和低温方案。

ABSTRACT Lisa Xu 9523082 Heat transport between blood vessels and their surrounding tissues will be studied theoretically and experimentally. The focus of the work is on matched pairs of blood vessels between 80 and 200 microns in diameter, the model of which will be an exteriorized rat spinotrapezius muscle. The experimental approach includes infrared imaging of the tissue preparation and Doppler velocimetry of the blood flow. Exisitng analytical models will be evaluated and extended to support the experimental findings. Applications include tissue freezing, cryopreservation, laser surgery and hypothermia protocols.
