“…The addition of shimming coils could help improve field homogeneity in the imaging region. One alternative is an emerging technology called superconducting fibers that can achieve more efficient generation of the magnetic field [25]. These fibers are made with an iron core and fused silica cladding, and are capable of exhibiting superconductivity for an extended period of time after injection with liquid helium [26].…”

Multi-modality imaging is essential for diagnosis and therapy in challenging cases. A Holy Grail of medical imaging is a hybrid imaging system combining computed tomography (CT), nuclear imaging, and magnetic resonance imaging (MRI) to deliver registered morphological, functional, and cellular/molecular information simultaneously and quantitatively for precision medicine. Recently, a unique imaging approach was demonstrated that combines nuclear imaging with polarized radiotracers and MRI-based spatial encoding. The detection scheme exploits the directional preference of γ-rays emitted from the polarized nuclei, and the result is a concentration image with resolution that can outperform standard nuclear imaging at a sensitivity significantly higher than that of MRI. However, the method does not calculate the attenuation image. Here we propose to obtain MRI-modulated γ-ray data for simultaneous image reconstruction of emission and transmission parameters, which could serve as a stepping stone toward simultaneous CT-SPECT-MRI. This method acquires synchronized datasets to provide insight into morphological features and molecular activities with accurate spatiotemporal registration. We present a complete overview of the system design and the formulation for tomographic reconstruction when the distribution of polarized radiotracers is either global or limited to a region of interest (ROI). Numerical results support the feasibility of our approach and suggest further research topics.

“…Other application areas in which in-fi ber electrodes become highly relevant lie within superconductivity or in fast polarization switching or modulation, where particularly the former can open up new fi elds for fi ber optics such as integrated single photon detection. [70][71][72][73][74] It is important to highlight here that electrical conductivity has also been achieved by relying on other materials than crystalline solids. Polymer nanocomposites made out of a thermoplastic matrix loaded with carbon black particles have been shown to be compatible with the thermal drawing process in a variety of confi gurations.…”

The field of hybrid optical fibers is one of the most active research areas in current fiber optics and has the vision of integrating sophisticated materials inside fibers, which are not traditionally used in fiber optics. Novel in‐fiber devices with unique properties have been developed, opening up new directions for fiber optics in fields of critical interest in modern research, such as biophotonics, environmental science, optoelectronics, metamaterials, remote sensing, medicine, or quantum optics. Here the recent progress in the field of hybrid optical fibers is reviewed from an application perspective, focusing on fiber‐integrated devices enabled by including novel materials inside polymer and glass fibers. The topics discussed range from nanowire‐based plasmonics and hyperlenses, to integrated semiconductor devices such as optoelectronic detectors, and intense light generation unlocked by highly nonlinear hybrid waveguides.
