摘要： 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.

摘要： One or more light beam endowed with photonic orbital angular momentum generating devices are mounted at preselected locations on an insertable instrument to hyperpolarize nuclear magnetic dipoles in a region of interest. The hyperpolarized nuclear magnetic dipoles are caused to resonate, generating magnetic resonance signals. A controller controls gradient coils to induce a magnetic field gradient across the region of interest, such that the frequency of the resonance signals is indicative of spatial positions. A frequency-to-position decoder converts the resonance signal frequencies into spatial positions. A video processor combines the spatial positions and a portion of a diagnostic image from a diagnostic image memory into a combined image which depicts the location of the region of interest or a portion of the instrument marked on the diagnostic image and displays the combined image on a monitor.

摘要： The present invention relates to a device capable of producing a high resolution chemical analysis of a sample, such as fluid, based upon nuclear magnetic resonance (NMR) spectroscopy, where the nuclear magnetic polarizations of the sample are generated by sequentially illuminating the sample with a focused beam of light carrying angular orbital angular momentum (OAM) and possibly momentum (spin). Unlike in usual NMR used for magnetic nuclear resonance imaging (MRI) or spectroscopy, the invention does not make use of a strong magnet.

摘要： In magnetic resonance imaging (MRI), selected magnetic dipoles in a subject are aligned with a main magnetic field for later manipulation, and signals received after such manipulations are used to create image representations of the subject. One drawback is that even powerful magnetic fields can only align a very small percentage of dipoles in the region of the field. Electromagnetic radiation endowed with orbital angular momentum (OAM) aligns dipoles along the direction of travel of the radiation, but at a much higher percentage; as high as 100% of the dipoles in the region can be aligned. Resultantly, resonance signals emanating from the region are several orders of magnitude stronger than signals emanated using traditional MRI techniques. All electromagnetic radiation, including visible light can be endowed with OAM and used to hyperpolarize a region of interest.
