Need for a simpler method for ICP measurement
Several neurological conditions are associated with raised intracranial pressure. Traumatic Brain Injury alone affects nearly 70 million people each year worldwide. Today ICP is measured invasively by inserting a pressure sensor through a cranial burr hole. The invasive procedure is performed by highly specialized personnel and carries along a high cost and risk of infection and bleeding. Early diagnostics and treatment is important. Nisonic has developed the technology to enable non-invasive detection of increased intracranial pressure.
Dr. Llewellyn Padayachy introducing Nisonic’s non-invasive method to detect increased intracranial pressure using ultrasound
Ultrasound imaging for non-invasive detection of ICP
Nisonic has developed a novel method for measuring the static and dynamic properties of the optic nerve sheath to detect the patient’s intracranial pressure. The method has been developed by engineers at SINTEF, Trondheim, Norway and neurosurgeons at Red Cross War Memorial Children’s Hospital, University of Cape Town in South Africa. The ultrasound system consists of a dedicated probe for transorbital ultrasound imaging together with advanced machine learning algorithms for automatic measurements and guiding.
Fast and simple
A few minutes per eye
No equipment calibration
Easy to use
Guided probe positioning
Better patient care
Enables earlier treatment
Reduced invasive interventions
Nisonic AS is a medical device company developing products for non-invasive detection of intracranial pressure (ICP) using ultrasound imaging and machine learning. The company was established in 2017 in Trondheim, Norway, and is a spin-out from SINTEF Medical Technology. Ultrasound experts and neurosurgeons have been working together since 2013 combining world leading ultrasound technology with clinical expertise to develop the new method for detecting intracranial pressure.
