RTI Mako Receives PTB Approval and Continues Its Success Story in X-ray Dosimetry
In July 2026, RTI Mako achieved PTB approval, one of the highest certification levels for an X-ray dosimeter. This represents a significant milestone in the ongoing development of the Mako platform.
The PTB (Physikalisch-Technische Bundesanstalt) in Germany is one of the world's leading reference laboratories for X-ray dosimetry. As part of the approval process, the PTB evaluates the performance of a measuring instrument based on the requirements of the German Measurement and Calibration Ordinance (MessEV), the Measurement and Calibration Act (MessEG), and relevant IEC standards, including IEC 61674 for dosimeters for diagnostic X-rays.
Mako underwent comprehensive testing that included measurement accuracy, energy dependence, dose rate dependence, the effects of temperature and humidity, long-term stability, repeatability, and electromagnetic compatibility (EMC). The entire firmware and software chain was also evaluated as part of the certification process.
Mako received certification for all three application areas: R/F (radiography/fluoroscopy), mammography, and CT. Certification across this broad range of applications serves as strong, independent validation of Mako’s performance and versatility as a comprehensive solution for quality assurance in diagnostic radiology.
This certification allows for the sale of certified Mako configurations in Germany as well as in other markets where PTB certification is recognized or required. It also provides customers worldwide with an important independent benchmark for Mako’s measurement quality and performance.
Trust from Customers Worldwide
Mako represents the latest generation of X-ray QA technology from RTI. The PTB certification provides customers and sales partners with further independent confirmation of its performance.
For customers in regulated markets, this certification is an important requirement. For customers in other parts of the world, it provides additional assurance that Mako has been independently tested by one of the most respected metrology institutions in this field.
A Tradition of Innovation in X-Ray Dosimetry
RTI's experience with PTB type testing dates back to around 1990, when the PMX-III became the first solid-state dosimeter to successfully pass the PTB type test.
Since then, RTI has continuously developed new generations of X-ray measurement technology. Barracuda, Piranha, and Cobia also successfully obtained PTB approval as technology and regulatory requirements continued to evolve.
With the PTB certification now granted to Mako, the latest generation of RTI measurement technology continues this tradition.
“PTB approval has been an important benchmark for RTI’s measurement technology for more than 35 years. The fact that Mako has successfully completed this rigorous process is a strong endorsement of the development work that went into the product, as well as its metrological performance. It gives our customers additional assurance that Mako meets the high standards they expect from RTI.” Sören Sturesson, Product Management & Technical Manager, Calibrations, RTI Group
