Abstract Over almost five decades of development and improvement, Magnetic Resonance Imaging (MRI) has become a rich and powerful, non-invasive technique in medical imaging, yet not reaching its physical limits. Technical and physiological restrictio

We derive exact expressions for the relativistic redshift and timing between observers in various configurations in stationary spacetimes for the purpose of chronometry, i.e., relativistic gravimetry based on clocks. These observers are assumed to be

One major objective of Geodesy is the observation of the Earth, its gravity field and climate. To study subtle but impactful changes in the gravitational field, novel paradigms and high-precision measurement schemes are emerging.According to Einstein

Conventional geodesy builds on (the concepts of) Newtonian gravity. Thus, at the level of a relativistic theory of gravity, the underlying framework needs to be extended and basic notions need to be generalized. This opens an entirely new perspective

Metamaterials, in particular 2D metasurfaces, offer great potential to advance the measurement efficiency in Magnetic Resonance Imaging (MRI). The signal-to-noise ratio (SNR) can be improved significantly in a multifold of applications. One major dra

A height definition in terms of geopotential numbers offers a variety of advantages. Moreover, from the theoretical point of view, such a definition is considered more fundamental. We know, however, that relativistic gravity (here General Relativity)
