    Abstract: A protective sleeve reduces electromagnetic energy propagation from the magnet bore of a magnetic resonance imaging device (MRD) to the surrounding environment and prevents electromagnetic energy in the surrounding environment from contaminating an MRI reading. The protective sleeve comprises a distal portion configured for insertion within the bore and a proximal portion attachable to the MRD aperture. The sleeve is configured for inserting a body part for insertion within the MRD's open magnet, with the imaged portion of the body part protruding from the distal end of sleeve into the MRD's volume of interest. The sleeve comprises, or is connected to, one or more sensors configured to detect movement, acceleration or dislocation of at least one portion or segment of the body part to be scanned.

    Abstract: A combined PET/MR system includes an MR subsystem including a main field magnet (14) which generates a stationary magnetic field through an examination region (16), a gradient magnetic field system (18, 20, 22, 24) which applies magnetic field gradients across the examination region, and an RF system (26, 28, 32, 34, 36, 38) that applies RF excitation pulses to excite resonance in a subject in the examination region and receive magnetic resonance signals from the subject. A PET detector module (70) which is permanently or removably fixed in the examination region (16) to detect radiation from radiopharmaceuticals injected into the subject causes distortions in the magnetic field gradients. A plurality of probes (90) which are mounted in a fixed relationship to the PET detector module (70) measure magnetic field strength. A gradient magnetic field distortion correction system (110) determines distortions caused in the gradient magnetic fields and corrects the magnetic resonance signals accordingly. The PET detector module includes a plurality of RF shielded detector units (132) which are mounted in a circumferentially spaced relationship with a gap (136) therebetween through which RF excitation pulses and magnetic resonance signals pass.

    Abstract: An NMR probe comprising an RF resonator 48 serves in a first mode for conventional sensitivity optimized studies of abundant samples at frequency ω 0 , and in a second mode for independent sensitivity optimized studies of micro sample quantities at frequency ω 0 through use of a removeably insertable self-resonant micro-coil 50 within the RF resonator 48 and closely surrounding a micro sample, that is preferably independently removeably insertable within the micro-coil. The NMR probe exhibits an enhanced tuning range to resonate in its first mode and in the second mode to inductively couple to the self-resonant micro-coil 50 to induce self-resonance of the micro-coil 50 at ω 0 .
