Web27 apr. 2016 · (iii) Magnetic field gradient coils, which induce a spatial dependence of the nuclear precession frequency and can be used for coherence order selection, measurements of diffusion, and MRI. (iv) Shim coils, which are used to produce as homogeneous a magnetic field as possible throughout the sample. Web14 aug. 2016 · The magnetic field generated by an electromagnet has been used in protein crystallization for several decades. The first electromagnet (NPS 60 TS, Nihon Kohmitsu Co., Ltd., Nagoya, Japan) for protein crystallization has a static magnetic field of 0.1–1.6 T (homogeneity ±1%). The gap between the two poles for a deposited sample is 12 mm.

Web1 mrt. 2007 · Magnetic field homogeneity is crucial in many magnetic resonance … WebThis paper presents a mathematical analysis of the magnetic field homogeneity for an Equilateral Triangular Helmholtz (ETH) coil. The magnetic field analysis is based on the Biot-Savart law in which a Taylor series approximation is performed to obtain the analytical distance that complies with the Helmholtz condition between the pair of coils.

WebFor the analysis of magnetic field homogeneity and power consumption, two scenarios were considered: by taking the radius of the circular coil equal to half of the side length of the square and equilateral triangular coils and then equating the perimeters of all of them. WebBackground: Magnetic field inhomogeneity in magnetic resonance imaging (MRI) is caused by the inherent properties of the main magnet, external ferromagnetic components surrounding the magnet, and the patient itself. Significant deviations from magnetic field inhomogeneity can create artifacts in MRI images, thereby compromising image quality.

WebDepending on the value of the desired magnetic field, these can be permanent magnets or electromagnets and, more frequently, various coils (solenoids) fed by DC, AC or impulse current.
