Abstract: Methods, apparatuses and systems facilitating the configuration of parameters controlling utilization of a network resource. In one embodiment, the present invention allows a network administrator to quickly and easily configure effective bandwidth utilization controls and observe the results of applying them. According to one embodiment, a network administrator is presented with an interface displaying the most significant traffic types with respect to a bandwidth utilization or other network statistic and allowing for the association of bandwidth utilization controls to these traffic types.

Abstract: A coil for creating improved homogeneity in magnetic flux density in a radio frequency resonator for magnetic resonance imaging and spectroscopy of the human head. The coil has a plurality of conductive members. Each of the conductive members has a linear portion and a tapered portion. The conductive members are arranged to form a first opening having a first diameter and a second opening having a second diameter, with the second diameter being different from the first diameter. The tapered portions of the conductive members provide the coil with a substantially homogeneous pattern of magnetic flux density in at least one of three orthogonal imaging planes of the coil.

Abstract: A method for creating improved homogeneity in magnetic flux density in a radio frequency resonator for magnetic resonance imaging and spectroscopy of the human head. A tapered birdcage resonator is also provided. The tapered birdcage resonator includes two electrically conductive rings and a plurality of rods or conductor legs. The first electrically conductive ring forms an inferior end of the coil. The plurality of legs extends from the first electrically conductive ring. Each of the plurality of legs has a linear portion and a tapered portion. The second electrically conductive ring forms a superior end of the coil and is connected to the tapered portion of the plurality of legs.

Abstract: A magnetic resonance imaging receiving coil having an improved signal-to-noise ratio comprising two or more separate quadrature volume coils, each intercepting the two quadrature components of the magnetic resonance signal within its own sensitive volume, and the two or more quadrature coils being magnetically isolated from each other by overlap geometry along the axis normal to the plane of the magnetic resonance rotating field. The coils are connected to independent image processing channels of a data acquisition system, the outputs of the processing channels being combined to form an overall image.

Abstract: A quadrature surface probe comprising two individual mirror image coil loops arranged so that the magnetic field vectors of the respective coil loops are substantially perpendicular. An area of overlap between the first and second coil loops is adjusted to minimize the mutual coupling between the individual coils. Also disclosed is the method of manufacturing the quadrature surface probe.
