Noninvasive Measurement of Cerebrospinal Fluid Flow in Shunted Hydrocephalus: Protocol for Scanner Calibration and Multisite Data Collection [PDF]

JMIR Research Protocols
BackgroundVentricular shunts divert cerebrospinal fluid (CSF) in patients with hydrocephalus, which can be lifesaving. Untreated shunt failure may lead to increased intracranial pressure and neurological injury.

Adjustable shunts and proton therapy: a magnetic combination

Child's Nervous System, 2023
Due to evidence for proton beam therapy (PBT) in pediatric central nervous system (CNS) tumors, compact proton therapy systems became commercially available to allow better integration in a hospital setting. However, these systems have a non-zero magnetic field at the level of the patient.

White matter changes should not exclude patients with idiopathic normal pressure hydrocephalus from shunt surgery

Fluids and Barriers of the CNS, 2022
Introduction White matter changes (WMC) on brain imaging can be classified as deep white matter hyperintensities (DWMH) or periventricular hyperintensities (PVH) and are frequently seen in patients with idiopathic normal pressure hydrocephalus (iNPH ...

Leakage Inductance Calculation for Planar Transformers With a Magnetic Shunt [PDF]

IEEE Transactions on Industry Applications, 2013
The magnetic shunt is generally inserted in a planar transformer to increase the leakage inductance, which can be utilized as the series inductor in resonant circuits such as the LLC resonant converter. This paper presents a calculation methodology for the leakage inductance of the transformer with a magnetic shunt by means of the stored magnetic ...
