the Intera 3 T high field system, the first with a compact magnet, which is built on the same platform as the 1.5 T, is targeted to high-end neurological, orthopedic and cardiovascular imaging applications with maximum patient comfort and acceptance without compromising image quality and clinical performance. Useable for clinical routine and research. The Intera systems offer diffusion tensor imaging (DTI) fiber tracking that measures movement of water in the brain and can therefore detect areas of the brain where normal movement of water is disrupted.

Advantages of low field imaging are the small-sized 5 Gauss fringe field and therefore the less static magnetic field exposure for the surrounding area, as well as less contraindications causing lower risks for the MRI safety by implemented metal and magnetic devices and equipment.
Low field systems are sometimes for restricted use, e.g. dedicated extremity scanner or open MRI devices. Open MRI devices equipped with permanent magnets are well-suited for MR guided interventions because these machines combine the lower magnetic fields of this type of magnets and the better patient access of open MRI scanner.
In some cases, the contrast of different tissues is better at lower field strength, depending on their T1 or T2 relaxation times. The disadvantage of the lower signal to noise ratio are a poor resolution and a longer scan time for a good image quality.
