我们以前已经开发了一种混合微波光学系统,以监测微血管的变化,在肌肉中的热激发。混合探头能够使用温和的微波(1-3 W)从皮肤表面诱导深层热量,并将组织温度提高几摄氏度。这会导致血管舒张,并且混合探头使用近红外光谱检测随后的血容量增加。混合探头还配备了皮肤冷却系统,可以降低皮肤温度,同时允许微波加热更深的组织。混合系统可用于评估脉管系统响应于热刺激的状况。在本确认研究中,使用热成像评估微波加热后体模和人小牛表面的温度分布。结果表明,该混合系统能够改变皮肤温度与微波加热和皮肤冷却的组合。它还可以检测氧合/脱氧血红蛋白浓度变化方面的热响应。
We have previously developed a hybrid microwave-optical system to monitor microvascular changes in response to thermal provocation in muscle. The hybrid probe is capable of inducing deep heat from the skin surface using mild microwaves (1–3 W) and raises the tissue temperature by a few degrees Celsius. This causes vasodilation and the subsequent increase in blood volume is detected by the hybrid probe using near infrared spectroscopy. The hybrid probe is also equipped with a skin cooling system which lowers the skin temperature while allowing microwaves to warm up deeper tissues. The hybrid system can be used to assess the condition of the vasculature in response to thermal stimulation. In this validation study, thermal imaging has been used to assess the temperature distribution on the surface of phantoms and human calf, following microwave warming. The results show that the hybrid system is capable of changing the skin temperature with a combination of microwave warming and skin cooling. It can also detect thermal responses in terms of changes of oxy/deoxy-hemoglobin concentrations.
