摘要： Measurement of blood flow rate in a convenient manner has been enabled by using a simple device constitution and a simple signal processing technique. A measurement mechanism having both the function of measuring temperature of the measurement site and the function of applying a thermal load to the measurement site is used, and a process of extracting temperature change associated with the recovery of the surface temperature by the blood flow is conducted from the measurement results obtained by the measurement mechanism.
