A primary standard in metrology is a standard that is sufficiently accurate such that it is not calibrated by or subordinate to other standards.
Primary standards are defined via other quantities like length, mass and time. Primary standards are used to calibrate secondary measurement standards.

“The MetroMRT project was a watershed in that it is the first time that the disciplines of clinical science and metrology have combined to solve the problem of individual patient dosimetry in molecular radiotherapy, and to bring it into line with all other modalities of radiotherapy.”

“Dosimetry is difficult, and with no standard methods available the implementation requires a level of commitment that regular non- research clinics cannot afford. So there is a considerable inertia to be overcome before individual MRT dosimetry becomes the standard of care in every clinic.”

Aim: To provide the metrology for the clinical implementation of absorbed dose calculations in Molecular Radiotherapy (MRT). The project builds on the results and outputs from MetroMRT. The focus of this follow-on project is clinical implementation and it is strongly directed by the involvement of leading MRT clinics across Europe as well as building on metrology expertise.

The ultimate aim of the project is to encourage and assist European MRT clinics, and those worldwide, to adopt dosimetry as a routine part of patient treatment and to bring MRT into line with other radiotherapy modalities.
The project will also support compliance with the EC Directive 2013/59/EURATOM, which states that individual dose planning for radiotherapy patients (including MRT) must be enforced in legislation by EU member states by 6th February 2018.
