MRI Shielding Optimization in Opera – 15 minute overview

Published on 25 Aug 2017

In this 15-minute presentation we show the benefits Opera Optimizer offers when used in conjunction with magnetostatic analysis for MRI shielding applications. We also demonstrate the benefits of the new “thin plate” boundary condition, which increases efficiency without compromising accuracy, and how Opera provides the ability for MRI shielded room designers to customize the Modeller [...] Posted in Magnets,Magnets Paper,MRI / NMR Magnets

How to design for MRI magnets

Published on 11 Jul 2017

In this blog we’ll look at the design of shielding for a known MRI magnet, but also at the solution to developing a model of the magnet when only fringe-field maps are available. The basic ground-work of what has become known as MRI was laid in the 1950’s but it wasn’t until the 1970’s that [...] Posted in How to...,Magnets,Magnets Paper,MRI / NMR Magnets

Optimization and inverse modelling for MRI shielding applications

Published on 07 Feb 2017

By Chris Riley In this blog post I take a look at MRI shielding, both looking at the design of the shield and the inverse issue when there is a need to develop a suitable model for the magnet. It’s true to say the first work in this area began in the 1950s but it was [...] Posted in MRI / NMR Magnets

Optimization and inverse modelling for MRI shielding applications (part 2)

Published on

By Chris Riley The left view shows the objective function space and the right the design variable space. In the 3 dimensional space the blue crosses mark the most optimal Pareto solutions, the red crosses mark other feasible solutions and the green crosses mark results that have failed the constraints so are not feasible. We can [...] Posted in MRI / NMR Magnets

MRI main field magnets

Published on 10 Nov 2016

Authors: Johan Overweg, Philips Research, Hamburg, Germany Abstract: MRI scanners come in various shapes and they are based on several distinctly different technologies to create the static background field (B0). Whatever the shape and the technology, all B0 magnets for MRI have in common that they generate a strong field, which has, within narrow tolerances, […]
