摘要: Methods and systems for providing treatment planning information for a neurology procedure, including neurosurgical procedures. A database containing historical data about historical procedures is accessed. Historical data relevant to a neurology procedure is determined, based on a determination of similarity to a set of data characterizing the neurology procedure. Historical instances of procedure parameters relevant to the neurology procedure are determined and displayed.

摘要: Systems and methods for imaging a subject with a magnetic resonance imaging system using magnetic field gradients generated by one or more gradient coils operating with gradient coil settings, such as gradient amplitudes and gradient slew rates, above a threshold at which peripheral nerve stimulation is likely to be induced in the subject. A dielectric assembly is positioned adjacent a skin surface of the subject such that the dielectric assembly attenuates the local electric fields induced by the magnetic field gradients, which would be likely to induce PNS when the dielectric assembly is not arranged adjacent the skin surface of the subject. As a result of the dielectric assembly placed adjacent the skin surface of the subject, the gradient coil settings can be increased above the threshold without inducing PNS in the subject.

摘要: A magnetic resonance imaging (MRI) system includes a set of magnet coils for generating a magnetic field. The set of magnet coils are composed of a superconducting material. The system further includes a mechanical cryocooler in thermal contact with the set of magnet coils and operable to reduce and maintain a temperature of the set of magnet coils below a transition temperature of the superconducting material, and an energy storage device coupled to the set of magnet coils. The energy storage device may be capable of receiving and storing energy dissipated from the set of magnet coils during rapid shutdown of the set of magnet coils. The system may also include a controller coupled to the energy storage device. The controller may be programmed to recharge the set of magnet coils using the energy stored in the energy storage device during the rapid shutdown of the set of magnet coils.

摘要: Some implementations provide a system that includes: a housing having a bore in which a subject to be image is placed; a main magnet configured to generate a volume of magnetic field within the bore, the volume of magnetic field having inhomogeneity below a defined threshold; one or more gradient coils configured to linearly vary the volume of magnetic field as a function of spatial location; one or more pulse generating coils configured to generate and apply radio frequency (RF) pulses to the volume of magnetic field in sequence to scan the portion of the subject; one or more shim gradient coils configured to perturb a spatial distribution of the linearly varying volume of magnetic field; and a control unit configured to operate the gradient coils, pulse generating coils, and shim gradient coils such that only the user-defined region within the volume of magnetic field is imaged.

摘要: The present disclosure provides a system for and a method of obtaining a magnetic resonance image by performing magnetic resonance imaging (MRI) at multiple slices simultaneously. The method comprises generating a multiband pulse sequence for spin-echo imaging, the pulse sequence comprising a multiband excitation pulse and at least one multiband refocusing pulse, wherein the multiband excitation pulse simultaneously excites multiple bands, wherein the at least one multiband refocusing pulse simultaneously refocuses the multiple bands, and wherein the phases of the bands excited by the multiband excitation pulse and the phases of the bands refocused by the at least one multiband refocusing pulse are set according to a single row of an orthogonal encoding matrix. The multiband excitation pulse and the at least one multiband refocusing pulse collectively form a multiband pulse pair.
