Abstract
An apparatus for measuring intracranial pressure constituted of: a transmitter arranged to transmit a first acoustic signal through a first cranial point; a receiver arranged to receive a second acoustic signal from a second cranial point; and a control circuitry, wherein the control circuitry is arranged to: extract from the detected second acoustic signal a first set of frequency components associated with the transmitted first acoustic signal; extract from the detected second acoustic signal a second set of frequency components associated with intracranial processes; and determine intracranial pressure responsive to the extracted first set of frequency components and the extracted second set of frequency components.

An apparatus for measuring intracranial pressure comprising:
- a transmitter arranged to transmit a first acoustic signal through a first cranial point;
- a receiver arranged to receive a second acoustic signal from a second cranial point, the second acoustic signal comprising:
- the first acoustic signal after having traveled from the first cranial point to the second cranial point;
- and
- a third acoustic signal comprising acoustic vibrations of intracranial processes, and
- a control circuitry,
- wherein said control circuitry is arranged to:
- extract from said received second acoustic signal a first set of frequency components, said first set of frequency components associated with said transmitted first acoustic signal;
- extract from said received second acoustic signal a second set of frequency components, said second set of frequency components associated with the third acoustic signal;
- determine intracranial pressure responsive to said extracted first set of frequency components and said extracted second set of frequency components;
- and
- output said determined intracranial pressure.
