Magnetic Resonance Imaging (MRI)
High-quality MRI images require a strong and extremely homogeneousA magnetic field with no or only a very small gradient. NMR teslameters can only be used in fields that... More magnetic field in the target area. MRI manufacturers measure the magnetic field and correct it, using special coils and/or small pieces of iron, in a process called shimmingIn magnet production, the process of making a magnetic field more homogeneous, by placing pieces of iron (shims) in the...

Magnetic resonance imagingMagnetic Resonance Imaging. Using NMR to image the interior of a solid body, usually for a medical diagnosis. More (MRI) has become a mainstay of medical imaging facilities. Superior soft-tissue contrast versus CT scans and the use of non-ionizing radio waves to visualize a rich matrix of functional information – including blood volume/oxygenation and localized metabolic activity within tumour sites – represent a winning combination for clinicians in the diagnosis and treatment of all manner of diseases.
Underpinning that clinical capability is an array of enabling technologies, the largest and most expensive of which is the superconducting magnetAn electromagnet built with superconducting wire. To remain superconducting, the coil has to be maintained at cryogenic temperatures, so it... More that sits at the heart of today’s cutting-edge MRI scanners. Clinical MRI
machines typically have a magnetic-field strength in the rangeThe range of a probe is defined by the minimum and maximum field strength it can measure. On an instrument,... More 0.1 to 3.0 T – though research systems for human and small-animal applications are available at much higher fields. In every case, these systems require a magnetic field that combines extreme stability with extreme uniformity (to within a few ppmParts per million, or 10-6. Bigger than a ppb, but still pretty darn small. More) to ensure optimal imaging performance.
To service that need, we have developed a portfolio of measurement tools and accessories to enable MRI equipment manufacturers to quantify and map the magnetic subsystems at the heart of their clinical MRI scanners.
