Into the Future with Metrology - The Challenges of Medical Technology

Innovation Cluster for Health

Medical measurements have a long tradition at PTB, but they have an even greater future as the development towards quantitative and individualized medicine represents a great challenge for metrology. The measurements have to be accurate and reliable, and they have to create confidence. This is where PTB has its core competence. PTB ensures the traceability of many important measurement procedures required, for example, by the EU's In Vitro Diagnostic Medical Devices Directive, but also by the German Medical Devices Act. With its measurement capabilities, PTB is the world leader in this field. According to the Measures and Verification Act, it is the only notified body in Germany to carry out type examinations of sound level meters. With its statutory mandate, PTB also plays an important role in dosimetry. Metrology is indispensable for one of the most important developments in medicine: the trend towards an increasing number of quantitative measurements. PTB is at the forefront of this research, for example, in the field of quantitative magnetic resonance imaging. Here, the aim is to make the measurements more and more reliable and comprehensible. In this extremely complex interdisciplinary field, intensive collaborations with suggestions and ideas coming from all participants are essential. Therefore, PTB wishes to further intensify its existing good contacts with physicians, hospitals and the medical technology industry. If you are interested, please do not hesitate to contact us!

Audiometers are calibrated based on reference hearing thresholds. These thresholds are determined by standardized procedures and based on a representative, normal hearing group of test subjects. Often, also at PTB, these data are measured by means of automated routines, which evaluate response times of the test subjects to a stimulus. The evaluation of the response times by the applied algorithms...

Teilnehmende des NGS-Workshops in der PTB Berlin

How great is the need for metrologically assured, i.e., standardized and reliable, new methods of gene sequencing? This was the question that researchers from the PTB in Berlin asked experts from science and industry at a workshop ("Metrology Needs for Next Generation Sequencing") on September 28. The answer was clear: the need is very high. PTB sees this as a mandate to continue working...

Künstliche Intelligenz, meist in Form neuronaler Netze, wird bereits häufig eingesetzt, um Empfehlungen für menschliche Entscheiderinnen und Entscheider auszusprechen oder die Entscheidungen gleich selbst zu treffen. Doch aufgrund welcher Kriterien eine bestimmte Entscheidung getroffen wird, bleibt für Nutzerinnen und Nutzer oft undurchschaubar. Dem Bedürfnis entsprechend, KI erklärbar zu machen,...

Mit weltweit mehr als 100 Millionen Untersuchungen pro Jahr ist die Magnetresonanztomografie (MRT) das zweitwichtigste medizinische Bildgebungsverfahren nach dem Röntgen. Doch wer ein Implantat trägt, muss oftmals auf diese potenziell lebensrettende Diagnosemöglichkeit verzichten oder eine geringere Bildqualität in Kauf nehmen. Insbesondere aktive Implantate wie Herzschrittmacher und...

Bisher weiß man nicht genug darüber, wie Schall auf Menschen wirkt. Eine große Studie der Physikalisch-Technischen Bundesanstalt (PTB) Braunschweig soll das ändern. In diesem und dem nächsten Jahr will die PTB-Arbeitsgruppe 1.61 „Hörschall“ an etwa 200 Personen die Wirkung von Geräuschen untersuchen, denen die Bevölkerung durch voranschreitende technologische Entwicklungen, auch aufgrund des...
