Abstract: 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.

Abstract: An imaging method uses a plurality of sets of carbon nanotubes. Within a set the carbon nanotubes carry markers for a respective receptor that is specific for the set and the carbon nanotubes have a geometry, characterized for example by a chiral number that gives rise to an electromagnetic absorption peak at a wavelength specific to the set. An image is formed by transmitting electromagnetic radiation to a body, substantially at the wavelengths of the absorption peaks of the sets, e.g. time multiplexed with each other, and detecting for example an ultrasound response to absorption of the transmitted electromagnetic radiation. Different images of the electromagnetic absorption as a function of position in the body are formed for different wavelengths.

Abstract: 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.

Abstract: A device capable of producing a high resolution chemical analysis of a sample, such as fluid, is based upon nuclear magnetic resonance (NMR) spectroscopy. 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 a typical NMR used for magnetic nuclear resonance imaging (MRI) or spectroscopy, the present device does not make use of a strong magnet.
