Abstract:
A magnetic resonance examination system comprises an RF-system for inducing resonance in polarized dipoles and receiving magnetic resonance signals from an object to be examined. A thermometry module dervies a temperature distribution of the object to be examined from the magnetic resonance signals. The magnetic resonance examination system further comprises a photonic-based hyperpolarization device with a photonic source for emitting electromagnetic radiation, a moder converter, such as a phase hologram to impart orbital angular momentum to the electromagnetic radiation and via spatial filter to select from the phase hologram a diffracted photonic beam endowed with orbital angular momentum for polarizing the dipoles via transferred orbital angular momentum.
