Systems and methods for simultaneously acquiring three-dimensional data from multiple different frequency bins with a magnetic resonance imaging ('MRI') system, and without frequency-encoding gradients, are provided. A multiband radio frequency ('RF') pulse is used to excite spins associated with multiple different resonance frequency offsets, and a fully phase-encoded acquisition is used to acquire data, which may be spectrally-resolved data, from magnetic resonance signals formed in response to the multiband RF pulse.

A system and method for accelerated magnetic resonance imaging (MRI) using spectral sensitivity information are provided. The MRI system is used to acquire k-space data from a subject that when positioned in the main magnetic field of the MRI system causes inhomogeneities in the main magnetic field. Spectral sensitivity information is derived from the acquired k-space data. In general, the spectral sensitivity information relates specific resonance frequencies to distinct spatial locations in the main magnetic field of the MRI system. One or more images of the subject may be reconstructed from the acquired k-space data using the produced spectral sensitivity information to spatially encode the acquired k-space data. By using the spectral sensitivity information to provide spatial-encoding, the data acquisition can be accelerated, for example, by undersampling k-space. In addition, using the provided system and method, clinically viable images can be obtained in the presence of severe off-resonance.

A device for controlled orientation of a person's cervical spine that is compatible with medical imaging machines. The device is capable of rotation about the axis of a patient's spinal column independent of, or in addition to, flexion/extension of a patient's spinal column. The device may incorporate locking mechanisms to secure rotational orientation and may include quantitative indicators of the degree of rotation.
