Structural reinforcements

The installation of low-field open magnetic resonance tomographs is becoming increasingly common. The increasing popularity of these heavy diagnostic apparatuses, increases the likelihood that Clients will retreat to install them no longer only in the basements of buildings, but also on upper floors. This clashes with the need to make structural adjustments so that the considerable weight of these permanent magnets (ranging from 1 to 20 tons even!) can be tolerated.

Techno Shield over the past five years has also considered offering structural consulting to its clients, manufacturing custom metal structural supports on site , in materials compatible with MRIs. These are mostly metal frames, designed to support the weight of the magnets without interfering with the building footprint, to be erected in a couple of days at most, and to allow magnetostatic shields and Faraday cages to be assembled in a short time frame (one week to one month for higher field machines, with more complex installations).

Optimizations

Of course, the choice of materials is decisive in order not to compromise the homogeneity of static magnetic field in the volume of investigation of magnetic resonance tomographs, indispensable for the restitution of high quality diagnostic images. The appropriate choice and distribution of the materials of which the supports are made, makes even more easy the operations of shimming of the magnets, characteristics of the first commissioning and calibration of this type of diagnostic tools.

These supports, finally, are optimized and harmonized with the magnetostatic screens, which is often necessary to install around the Faraday cages to contain the magnetic fields generated by the MRI tomographs, confining them according to the dictates of the regulations and laws in force.
