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.

Ultrasound imaging for non-invasive detection of ICP

Nisonic has developed the FAST ICP software for automated analysis of transorbital ultrasound images, implementing novel and patented methods for measuring the static and dynamic properties of the optic nerve sheath to predict 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 Nisonic FAST-ICP software is estimating image-derived biomarkers for raised ICP in real-time. The software can be installed in Windows based computers and in ultrasound devices. The unique FAST-ICP software has the potential to transform any standard medical ultrasound console to a device that can predict the intracranial pressure. To allow for non-invasive measurement of ICP, the user simply performs an transorbital ultrasound examination, which typically takes less than a minute.

The Fast-ICP software provides real-time guiding to simplify image acquisition, and performs automated AI-based image processing and quantification of multiple parameters to predict the patients ICP. The Nisonic methods has been clinically validated to detect raised ICP in children, adults with traumatic brain injuries and in adults with Aneurysmal Subarachnoid Hemorrhage.

The Company

Nisonic AS is a medical software 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. 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.

Development/Clinical trial

Started clinical study at Oslo University Hospital Ullevål (halted during Covid) in adults with Traumatic Brain Injury.

Continuous refinement of the automated measurement methods in the FAST-ICP software.

2021
First CE-marked product

Nisonic P-100 CE-marked May 2021 – Off the shelf ultrasound system running the Nisonic FAST-ICP software. It proves that the Nisonic software is able to perform image acquisition guidance and automated image processing in real time when installed on a ultrasound device.

The FAST-ICP software development was audited by Notified Body with respect to compliance with IEC 62304 and ISO 14971, without any findings. The Nisonic P-100 ultrasound device is used for data collection in clinical studies.

2023-2024
Publication of results in TBI study - initiation of new study

The results of the FAST-ICP processing in TBI patients resulted in two clinical papers. The results of the clinical trial shows that it is possible to differentiate low and high ICP by using the Nisonic methods to estimate optic nerve sheath diameter ONSD and the dynamics of the optic nerve sheath as expressed by the Deformability Index (DI).

Important papers, as it shows that the results obtained in children are replicated in an adult patient population.

 

New study initiated in 2023 at Oslo University Hospital, Rikshospitalet, in adults with subarachnoid hemorrhage (SAH).

2025 -
New clinical paper, new AI developments, expanding clinical trials

The first results of the SAH study published, demonstrating that the automated measurements of ONSD can detect the condition of raised ICP with high sensitivity, and in particular when excluding patients that have had surgical entry into the basal cisterns prior to the measurements.

It is the first study in the world that demonstrates that the optic nerve sheath diameter as automatically measured by the Nisonic FAST-ICP software can be used as a non-invasive measure raised ICP.

New studies are being initiated and planned, involving indications in children and in adults.

Nisonic reaches a milestone when it comes to number of ultrasound images collected from clinical studies: 200 000 records, most of them having associated invasive ICP measurement registered during the ultrasound examinations.

The images are used for training of neural networks (deep learning), and Nisonic is training a new refined AI-model with additional image based biomarkers for quantification of ICP. The prototype model has been launched and is to be used in retrospective and prospective clinical studies.

Preparing for market launch: Installing the FAST-ICP in established Point of Care Ultrasound devices for use in Europe and USA.

 

 

 

Our product

  • The FAST-ICP software is intended to be installed as an App in ultrasound scanners including handheld ultrasound devices, and offers:

Guidance for probe positioning during transorbital ultrasound imaging

Automatic measurements based on advanced machine-learning algorithms


The FAST-ICP Software is currently research only and is being used in ongoing clinical investigator initiated research in USA, Europe and Africa. The AI based processing is currently being evaluated for a wide range of indications in children and in adults.

The Nisonic P-100 ultrasound system is available in a limited number for hospitals doing research on ICP.
