Magnetic resonance imaging (MRI) is an important imaging procedure in cardiology. To date, only qualitative imaging has been possible with MRI, since the measuring time is limited due to heart movements and breathing. A new image reconstruction procedure has now been developed at PTB. This method quantifies the biophysical parameters of the cardiac muscle with high spatial resolution and thus enables an objective diagnosis.

Accurate measurements of high voltages in the range of 200 kV require the use of voltage dividers. These devices divide high voltages into smaller ones that can only then be accurately measured. The size of the signal is determined by the scale factor. Up to now, this factor had to be determined by regularly calibrating the voltage dividers against national standards. At PTB, a self-traceable voltage divider has now been developed. It provides testing laboratories with a flexible tool. Its main principle is that seriesconnected resistors can be connected in parallel and adjusted. In this way, it is possible to save both operating expenses and time since there is no need for transporting the equipment to a metrology institute and setting it up there. (Technology Offer 484)
