摘要： A magnetic resonance imaging (MRI) apparatus suitable for radiotherapy. The apparatus includes two sets of coil pairs, each coil pair forming a Maxwell-like coil. The two sets of coil pairs share a common transverse plane, have opposing polarities, and define a common plane of symmetry and an imaging area. The two sets generate a substantially homogenous electromagnetic field in a first transverse direction in the imaging area and peripheral electromagnetic fields in a direction opposite to the first transverse direction in a peripheral area. The apparatus also includes at least one focusing magnet positioned in the peripheral areas to generate a focusing electromagnetic field in a focusing area, in a direction substantially the same as the first transverse direction. At least a portion of the peripheral electromagnetic fields is maintained in a defocusing area between the focusing area and the imaging area.

摘要： A local coil arrangement for a magnetic resonance apparatus has a support structure with an antenna arrangement and a sensor arrangement embedded in the support structure. The antenna arrangement has a number of magnetic resonance antennas. A magnetic resonance excitation signal can respectively be emitted by means of each magnetic resonance antenna and/or a magnetic resonance signal can respectively be received by means of each magnetic resonance antenna. The sensor arrangement has a number of magnetic field sensors and an evaluation circuit. The magnetic field sensors detect how large a static magnetic field is to which the local coil arrangement is exposed and output a corresponding output signal and supply a corresponding output signal to the evaluation circuit. The evaluation circuit determines a logical presence signal and outputs it. The value of the logical presence signal depends on whether a field strength of the static magnetic field is greater than a minimum field strength.

摘要： System(s) and method(s) for magnetic resonance imaging and spectroscopy, and magnetic resonance spectroscopic imaging (MRSI) are provided. A unified heteronuclear coil system includes a volume coil tuned to detect a first nuclei and a butterfly coil tuned to detect a second nuclei for simultaneous detection of both the first nuclei and the second nuclei signals from human breast tissue and perform MRIS. First nuclei and second nuclei each include 1H, 13C, 31P, 23Na, and 19F. The heteronuclear coil system affords detection of NMR-detectable chemicals specific to cancerous breast tissue to improve breast cancer diagnostic specificity. Adjustment of the heteronuclear coil system to detect various nuclei, combined with a specific pulse excitation sequence, facilitates chemical analysis that provides for chemical discrimination and characterization of compounds present in cancerous and other breast tissue as well as healthy breast physiology.
