The portable device is intended to assess exposure to electromagnetic fields produced by an MRI equipment. The device (dosimeter) allows to improve the analysis and study of the problems related to the exposure of the operators, starting from the technical-scientific aspects related to the exposure, also allowing to create a manual of best practices as well as to improve the professional training of operators. The dosimeter allows to: carry out the real-time measurement of exposure to the magnetic field, and to evaluate the induced electric field in different parts of the body thanks to the possibility of using several probes at the same time; to store the exposure values both in aggregate and detailed form; to provide staff with some recommendations on how to move around MRI room during the daily clinical practice; to archive personal exposure data on a remote server. The dosimeter can be used in all MR environments, characterized by static magnetic field values between 0.1T and 7T, for clinical or industrial applications.
To date, there are only a few examples on the market of devices for occupational exposure assessment to electromagnetic fields in magnetic resonance environments. The competitive advantages of our dosimeter concern the possibility of use in environments with high magnetic field scanners (up to 7T), of simultaneously measuring the exposure in multiple areas of the body with the use of different local probes, of analyzing data with innovative software, draw up a personal exposure report and use the data for training operators thanks to the use of interactive tools associated with the device (app, etc ...). The dosimeter could be included among the utilities provided by scanner manufacturers to their customers, in order to carry out a detailed risk assessment and contribute to epidemiological studies on the effects of electromagnetic fields.
