3. NMI measurement capabilities for magnetic quantities compared to health technologies demands
4. Discussion and Conclusion
Innovations in the healthcare sector along the last half-century have created a growing demand for metrological traceability of measurement results regarding magnetic quantities. This work discusses these challenging requests for traceability, from the lowest to the highest values of magnetic flux densities associated with
the recently developed biomedical technologies as well as other relevant health demands. The worldwide availability of quality metrological infrastructure for providing measurement standards appropriate to the demanding quantity range is analyzed based on the information of the BIPM key comparison database (KCDB) appendices. Results indicate that the demands for metrologically traceable measurement results regarding power frequency magnetic field exposure have demonstrated to be a notable driver toward the
establishing of metrological infrastructure by National Metrology Institutes. Although limitations of available measurement standards for magnetic quantities produce significant impacts on the possibility of meeting medical innovations’ demands, the recent fast expansion of comprehensiveness of declared CMC capabilities for ensuring metrological traceability of magnetic quantities points toward the possibility of meeting the demanding values from healthcare sector in the near future.
