This is not possible with conventional pocket exposimeters. Hence, this device allows head\u2010level field exposure to be measured, which can induce physiological effects on MRI workers, and which are required to be covered by managing the laboratory\u2010related safety hazards directive 2013\/35\/EU.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Using on\u2010chip monolithic three\u2010axis Hall effect magnetometers, recently introduced on the market, we developed an exposimeter with unprecedented accuracy, which allows the measurement of the magnetic field closed to the organs which are the most impacted by strong magnetic fields: the brain, the eyes, and the tongue.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The exposimeter prototypes were successfully tested around 3 T, 7 T, and 11.7 T MRI scanners on different workers and volunteers in real conditions. Comparisons with chest\u2010level measurements lead typically to lower values than exposure recorded at the head\u2010level, confirming the need for such head\u2010level assessments. Exposure of the head above the limits established by the directive was also recorded (&gt;2 T or &gt;2.7 T\/s).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This new exposimeter allows for a more accurate assessment of field exposure of MRI workers. Further improvements in the miniaturization and the usability of the exposimeter will allow us to disseminate the device and open the way to a larger\u2010scale study.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/mrm.30513","type":"journal-article","created":{"date-parts":[[2025,3,30]],"date-time":"2025-03-30T18:47:21Z","timestamp":1743360441000},"page":"867-875","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Monitoring the head exposure of MRI workers around 3 T, 7 T, and 11.7 T scanners using smart goggles equipped with a network of magnetometers"],"prefix":"10.1002","volume":"94","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8009-1210","authenticated-orcid":false,"given":"Hugo","family":"Nicolas","sequence":"first","affiliation":[{"name":"School of Life Sciences University of Applied Sciences  Muttenz Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6599-4988","authenticated-orcid":false,"given":"Corentin","family":"F\u00e9ry","sequence":"additional","affiliation":[{"name":"School of Life Sciences University of Applied Sciences  Muttenz Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4919-278X","authenticated-orcid":false,"given":"Thomas","family":"Quirin","sequence":"additional","affiliation":[{"name":"School of Life Sciences University of Applied Sciences  Muttenz Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-7777-6678","authenticated-orcid":false,"given":"Nicolas","family":"Weber","sequence":"additional","affiliation":[{"name":"IADI INSERM\u2010U1254 CHRU Nancy Brabois  Vandoeuvre\u2010l\u00e8s\u2010Nancy France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6090-0834","authenticated-orcid":false,"given":"Julien","family":"Oster","sequence":"additional","affiliation":[{"name":"IADI INSERM\u2010U1254 CHRU Nancy Brabois  Vandoeuvre\u2010l\u00e8s\u2010Nancy France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9245-6595","authenticated-orcid":false,"given":"Jacques","family":"Felblinger","sequence":"additional","affiliation":[{"name":"IADI INSERM\u2010U1254 CHRU Nancy Brabois  Vandoeuvre\u2010l\u00e8s\u2010Nancy France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9203-0247","authenticated-orcid":false,"given":"Alexandre","family":"Vignaud","sequence":"additional","affiliation":[{"name":"CEA NeuroSpin Universit\u00e9 Paris\u2010Saclay\/CNRS  Gif\u2010sur\u2010Yvette France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6049-3271","authenticated-orcid":false,"given":"Joris","family":"Pascal","sequence":"additional","affiliation":[{"name":"School of Life Sciences University of Applied Sciences  Muttenz Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,3,28]]},"reference":[{"key":"e_1_2_7_2_1","unstructured":"ICNIRP.Static Magnetic Fields (0 Hz).https:\/\/www.icnirp.org\/en\/frequencies\/static\u2010magnetic\u2010fields\u20100\u2010hz\/index.html"},{"key":"e_1_2_7_3_1","unstructured":"ICNIRP.LF (1 Hz\u2010100 kHz).https:\/\/www.icnirp.org\/en\/frequencies\/low\u2010frequency\/index.html"},{"key":"e_1_2_7_4_1","unstructured":"ICNIRP.Static Electric Fields (0 Hz).https:\/\/www.icnirp.org\/en\/frequencies\/static\u2010electric\u2010fields\u20100\u2010hz\/index.html"},{"key":"e_1_2_7_5_1","unstructured":"Directive 2013\/35\/EU of the European Parliament and of the Council of 26 June 2013 on the Minimum Health and Safety Requirements Regarding the Exposure of Workers to the Risks Arising From Physical Agents (Electromagnetic Fields) (20th Individual Directive Within the Meaning of Article 16(1) of Directive 89\/391\/EEC) and Repealing Directive 2004\/40\/EC;
