Systems and methods for making non-invasive physiological assessments by detecting induced acoustic emissions

Abstract

Systems and methods for assessing a physiological parameter of a target tissue wherein a pulse of focused ultrasound is applied to a target tissue site thereby inducing oscillation of the target tissue. By these systems and methods, a property of an acoustic signal emitted from the oscillating target tissue is measured and related to a physiological property of the tissue. Specific applications for systems and methods of the present invention include the assessment and monitoring of intracranial pressure (ICP), arterial blood pressure (ABP), CNS autoregulation status, vasospasm, stroke, local edema, infection and vasculitus, as well as diagnosis and monitoring of diseases and conditions that are characterized by physical changes in tissue properties.
