Abstract

An apparatus and method for measuring intracranial pressure non-invasively includes a frame that holds an acoustic sensor (e.g. a piezoelectric sensor) in place on the eyelid of a patient. The frame includes a means to adjust and control the amount of pressure that is exerted at the region of the eyelid that is in direct contact with the sensor. Changes intracranial pressure (which result in changes in dampening of acoustic signals transmitted through the cranium of the patient) are non-invasively detected by the acoustic sensor on the eyelid.
