[Microwave method of determining cerebral blood flow]. / Mikrovolnovyi metod opredeleniia mozgovogo krovotoka.

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.
