Abstract
A noninvasive method of quantitative assessment of cerebral blood flow based on heat clearance from brain tissues is described. The rate of heat clearance depends essentially on the blood flow. The employment of microwave techniques permits to warm the investigated brain zone and to record the temperature decrease extracranially. As a thermometer, a microwave radiometer was used. The experiments were carried out on cats. The method was tested by current vasoactive drugs.
摘要
描述了一种基于脑组织热清除的无创性脑血流量定量评估方法。热清除率主要取决于血流量。采用微波技术可以使被研究的脑区升温，并在颅外记录温度下降情况。使用微波辐射计作为温度计。实验在猫身上进行。该方法通过使用当前的血管活性药物进行了测试。
