Abstract
A sensor coil is located on guidewire or perfusion catheter and introduced into the body. First the sensor coil is isolated from blood flow and used to make a set of static measurements. Next the sensor coil is heated in the presence of blood flow and a set of dynamic measurements are made which reflect the blood flow past the sensor coil.
