Abstract
A physiological information processing method for automatically acquiring information relevant to a fluid flowing through a body of a subject using an ultrasonic sensor. The ultrasonic sensor includes a plurality of ultrasonic elements. The physiological information processing method includes acquiring reflection signals of ultrasonic waves, identifying, among the ultrasonic elements, two or more ultrasonic elements facing a vessel through which the fluid flows, analyzing a reflection signal of an ultrasonic wave associated with a first ultrasonic element of the two or more ultrasonic elements, analyzing a reflection signal of an ultrasonic wave associated with a second ultrasonic element of the two or more ultrasonic elements, identifying an angle of the vessel with respect to the irradiation direction of the ultrasonic wave, analyzing the reflection signal of the ultrasonic wave associated with the first ultrasonic element or the second ultrasonic element, and acquiring information relevant to the fluid.
