Abstract
The invention relates to a new method, as well as diagnosis. A non-invasive marker, systems and equipment are also included.
Claims20
A method for non-invasively determining a state of at least one marker selected from the group consisting of:
- a marker indicating possibly increased intracranial pressure of a patient and a marker indicating another condition affecting an optic nerve sheath of the patient, the method comprising:
- locating the patient's optic nerve sheath;
- monitoring motion of the optic nerve sheath using at least one of:
- a transducer device and data recorded with a transducer device, to detect displacements of the optic nerve sheath;
- using the detected displacements to determine a measure of stiffness of the optic nerve sheath;
- and
- using the detected displacements and the measure of stiffness to determine the state of the at least one marker.
An apparatus for non-invasively calculating at least one of a marker indicating possibly increased intracranial pressure of a patient and a marker indicating another condition affecting an optic nerve sheath of the patient, the apparatus comprising:
- an imaging system for locating the optic nerve sheath and for monitoring displacements arising from motion of the optic nerve sheath, the imaging system including at least one of a transducer device and data recorded with a transducer device;
- and
- a data analysis device configured to:
- use the displacements to determine a measure of stiffness of the optic nerve sheath;
- and use the detected displacements and the measure of stiffness to estimate the state of the marker.
A method for detecting pulsatile dynamics of an optic nerve sheath (ONS) or in a region surrounding the ONS, comprising the steps of:
- locating the ONS;
- choosing one or more locations around the ONS or in the region surrounding the ONS;
- and
- measuring the pulsatile dynamics at the one or more locations over a given time period or frequency.
