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!

Patientin im MRT

Riesenchancen oder Hochrisiko – oder beides? Künstliche Intelligenz (KI)  in der Medizin kann helfen, Menschenleben zu retten oder Geld im Gesundheitssystem zu sparen. Aber die sprichwörtliche Black Box, also der KI-Algorithmus, der schließlich eine Diagnose ausspuckt, macht vielen Menschen Angst. Deswegen forscht die PTB intensiv an Methoden, die die Qualität der eingesetzten Algorithmen oder der...

Ein MRT-Bild auf der Intensivstation (ungvar/ Adobe Stock)

Ein Magnetresonanztomograf liefert ganz ohne Strahlenbelastung äußerst detailreiche Bilder etwa von Herz oder Hirn. Aber zurzeit sind die Geräte so teuer, dass nur Kliniken und große Spezialpraxen sie sich leisten können. In einem EU-Projekt entwickelt die PTB ein MRT-Gerät, das kleiner, leichter und wesentlich preiswerter ist. Es bietet dank Open-Source-Hard- und Software ganz neue Möglichkeiten...

"KI-Tetris"

Eine Challenge für KI-Bilderkennungsmethoden: Bekannte Formen werden als bewusste Störung in ein Bild eingebaut. Die Frage lautet: Wird die KI diese Störung (quasi den "Tumor") erkennen? PTB-Forschende ermitteln, wie gut KI-Bilderkennungsmethoden dabei abschneiden. Die Frage lautet: Liefert die KI die richtige Erklärung?

Auf einer Intensivstation

Da echte Patientendaten strengem Datenschutz unterliegen, erzeugen Forschende synthetische Daten zum Trainieren ihrer KI-Systeme. Die PTB will ihnen einen Werkzeugkasten für die Qualitätsbewertung ihrer Daten zur Verfügung stellen. Er hilft auch dabei, das Recht der Einzelnen auf Privatsphäre zu schützen.
