Non-invasively measuring physiological process

摘要

Equipment (10) for non-invasively measuring a physiological process includes at least one receiver (12) to be placed relative to a body of a subject being examined to detect at least one signal from the body of the subject. A discrimination unit (20.1) determines if the at least one signal is a signal of interest associated with the physiological process. A processor (20) processes the signal of interest to enhance the signal of interest and suppresses other received signals that are not of interest.
