The process to produce an MR image includes nuclear alignment, RF excitation, spatial
encoding, and image formation. In simple terms, an magnetic resonance imaging (MRI) …

This paper proposes a finite-difference (FD)-based method for the design of gradient coils in
MRI. The design method first uses the FD approximation to describe the continuous current …

Standard gradient coils are designed by minimizing the inductance or resistance for an
acceptable level of gradient field nonlinearity. Recently, a new method was proposed to …

Gradient coil windings are typically constructed from either variable width copper tracks or
fixed width wires. Excessive power dissipation within these windings during gradient coil …

Gradient and shim coils were designed using boundary element methods with convex
optimisation. The convex optimisation framework permits the prototyping of many different …

Creating an effective gradient coil is essential for enabling portable, high-quality magnetic
resonance imaging (MRI). This study introduces a method that incorporates a power …

Ohmic heating is a serious problem in gradient coil operation. A method is presented for
redesigning cylindrical gradient coils to operate at minimum peak temperature, while …

Background Non-destructive structural evaluation of the osteochondral unit is challenging.
Here, the capability of high-field magnetic resonance imaging (μMRI) at 9.4 Tesla (T) was …

The operation of gradient coils typically requires large currents to be driven in resistive
copper wires. A major problem in gradient coil design is therefore the correspondingly large …

An important requirement for a gradient coil is that the uniformity of the generated magnetic
field gradient should be maximal within the active volume of the coil. For a cylindrical …
