The development of a new MRI magnet requires a rapid and reliable magnetic measurement system to verify and perfect the magnet model. Our standard product line covers most of your needs in this area. In addition, we work with you to develop custom and semi-custom solutions – for example, an adaptation to a new field strength or geometry, or for the passage from a reduced-scale to a full-sized model. Specifically adapted to your system, the solutions we provide for the Research & Development phases can also be used during production and installation, thus optimizing your investment and saving time in the complete product cycle.
Metrolab's single-point NMR magnetometers are as sophisticated as they are tough and easy to use. These versatile, ultra high-precision instruments are perfect for measuring the B0 fields typically encountered in MRI applications. They are suitable for simple hand-held field-strength checks, for example during ramping, as well as sophisticated long-term stability studies, simultaneous measurements at several locations, or even a simple field map. Metrolab's unique multi-point NMR teslameter systems allow computational models to be verified to a high order, thanks to their ultra high precision, a geometry adapted to the magnet, a high density of measurement points, and rapid acquisition time. The same field maps form the basis for a robust and rapid shimming procedure that can handle even the relatively poor field quality of a first prototype.
Metrolab's handheld three-axis magnetometer allows fringe fields to be mapped quickly and conveniently, whereas precision integrators – a standard tool for mapping accelerator magnets – can also be used effectively for high-precision studies of dynamic effects such as eddy currents.
