Abstract
A system and method that determines a blood flow rate in an area of a subject. The system includes a transmitter operable to transmit an electrical signal in the range of about 20 GHz to about 300 GHz to the area, a temperature sensor positioned adjacent the area, and a processor operable to determine the blood flow rate in the area based on the rate of change of temperature in the area as a result of the application of the electrical signal on the area and a power density value.
