Mpi based intracranial pressure (Icp) monitor for hydrocephalus patients

Intraventricular shunts are the conventional medical devices for the treatment of hydrocephalus. The most common and life threatening complication of the implanted devices is the probability of the blockage or the misalignment of shunts after the implantation procedure. The most common way to diagnose these complications is the application of Computed Tomography. Unfortunately, frequent exposure to x-ray radiation can have degrading effects such as memory loss, stroke-like symptoms, poor brain function and even it can lead to cancer. In this study, an elastic capsule filled with super paramagnetic iron oxide nanoparticles is used for the measurement of the intracranial pressure (ICP). The diameter of the capsule is measured by the magnetic particle imaging method (MPI). The performance of the proposed method is evaluated with a Matlab/SIMULINK model. © 2020 Sener et al.; licensee Infinite Science Publishing GmbH.
