NIST modelled and built the prototype device and also developed and tested various solutions used in the mini-spheres as contrast-enhancing agents and measurement reference markers.
The Units applying for model design appraisement for a new measurement instrument and prototype testing should provide a prototype of the new product, and the relevant technical documents and data.
