Power-Efficient Control of Non-Linear Magnetic Field Generators for MPI

The scaling of electrical power constitutes a significant challenge when adapting Magnetic Particle Imaging (MPI) to a human scale. The use of coils incorporating soft-iron cores serves to reduce power usage, but also introduces spatial imperfections and

Application of conjugate gradient least squares method in solving magnetic moments of magnetic targets based on magnetic dipole array model

AIP Advances
In order to solve the problem of magnetic targets magnetic field modeling, a magnetic dipole array model was established, a modeling inversion equation system was constructed, and the degree of sickness of the solved equation system under different ...

Finite-time singularity formation at a magnetic neutral line in Hall magnetohydrodynamics

, 2015
The formation of a current sheet in a weakly collisional plasma can be modelled as a finite-time singularity solution of magnetohydrodynamic equations.

Avian magnetoreception: elaborate iron mineral containing dendrites in the upper beak seem to be a common feature of birds

, 2010
The magnetic field sensors enabling birds to extract orientational information from the Earth’s magnetic field have remained enigmatic. Our previously published results from homing pigeons have made us suggest that the iron containing sensory dendrites ...

Measurements of magnetic field variations in the human brain using a 3D-FT multiple gradient echo technique

, 1995
A magnetic resonance 3DFT multiple gradient-echo technique was used for measurements of the proton spectrum for each voxel in the measured slice. Water, fat, magnetic field and T2 distributions in the head of a normal volunteer and a patient with ...

Stern-Gerlach effect without magnetic-field gradient

, 2003
The Stern-Gerlach effect is the well-known spin-dependent splitting of a neutral particle beam by a magnetic-field gradient. Guided by the pseudomagnetic analogy, we performed a similar experiment where no magnetic-field gradient is involved. The effect
