Abstract
A non-invasive cerebral spinal fluid pressure method and apparatus applies at least one signal to a head of a subject, where that at least one signal is provided at a frequency range that includes the brain resonant frequency. The received signal strength is an indication of the amount of cerebral spinal fluid pressure in the head of the subject.
Claims10
A method of estimating an intracranial pressure within a head of a subject, comprising:
- providing a signal to the head of the subject;
- measuring an amplitude of a received signal at a location on the head of the subject different from where the signal was provided to the head of the subject;
- and
- determining the intracranial pressure based on the amplitude of the received signal.
A method of estimating an intracranial pressure within a head of a subject, comprising:
- providing a signal to the head of the subject at at least two different times and at at least two different frequency values, respectively, that correspond to a brain resonant frequency and a harmonic of the brain resonant frequency;
- measuring an amplitude of a received signal at a location on the head of the subject different from where the signal was provided to the head of the subject, the measuring being performed at the first and second times;
- and
- determining the intercranial pressure based on the amplitude of the received signal at the first and second times.
The method according to claim 8, further comprising:
- providing a second signal to the head of the subject;
- measuring an amplitude of a second received signal at a location on the head of the subject different from where the second signal was provided to the head of the subject;
- and
- determining a change in the intracranial pressure based on a difference between the amplitude of the received signal and the amplitude of the second received signal.
An apparatus for estimating an intracranial pressure within a head of a subject, comprising:
- an adjustable headband that includes at least one transducer and one sensor, the at least one transducer providing a signal to the head of the subject;
- and
- a computation unit that estimates the intracranial pressure and that provides a signal to the at least one transducer to output the signal,
- wherein an amplitude of a received signal is measured by the at least one sensor at a location on the head of the subject different from where the signal was provided to the head of the subject, and
- wherein the intracranial pressure is estimated based on the amplitude of the received signal as provided to the computation unit by the at least one sensor.
