    摘要: Client network traffic data and server network traffic data regarding a number of network nodes is collected and then grouped by IP address. The network nodes are divided into logical groupings and the network traffic data is presented in the aggregate for all IP addresses in each logical group. The logical groupings may be further divided by protocol, application, port and/or logical group-to-group. Each logical group can be further generalized as either a set of IP addresses (e.g., a business group) or a specific logical link between one set of IP addresses to another set of IP addresses (e.g., a business group link). Either or both of these “groups” may be divided in further logical sub-groups: for example, by protocol, application, port and in the case of business groups, group-to-group. The logical groups provide facilities for initial problem detection and identification while the logical sub-groups provide facilities for troubleshooting and problem isolation.

    摘要: During monitoring of IP network traffic, network application monitoring metrics are extracted, aggregated into logical group types and subsequently analyzed by identifying group sets of the logical group types, correlating anomalous conditions across the logically grouped and aggregated metrics, and isolating the anomalous conditions to one or more related members of the logical group types. The metrics may include usage metrics, network performance metrics and application performance metrics.

    摘要: An apparatus and method are disclosed for improving imaging based on a time-series of images. In one embodiment, a time-series of images are acquired using a same imaging protocol of the same subject area, but the images are spaced in time by one or more time intervals (e.g, 1, 2, 3 . . . seconds apart). A sub-region is projected across all of the images to perform a localized analysis (corresponding X-Y pixels or X-Y-Z voxels are analyzed across all images) that identifies temporal components within each sub-region. In some of the sub-regions, the temporal components are removed when the amplitude of the component is below a predetermined amplitude threshold. The images are then combined using the sub-regions with reduced components in order to obtain a single image with reduced noise.

    摘要: An MRI probe/transmitter coil has a pair of concentric cylinders with a plurality of inductively coupled freely rotating resonant elements radially mounted between the two cylinders. The coil can be tuned both symmetrically by pivoting all the resonant elements uniformly or asymmetrically by tuning them individually. The coil is driven in quadrature by a quad-hybrid circuit. A substantial part of the electromagnetic energy is stored in the resonant elements outside of the loading region of the coil to reduce perturbation in the coil operation due to the characteristics of the test subject.

    摘要: Magnetic resonance imaging method and apparatus are provided for mapping the internal or bulk motion of an object by labeling the phase of a specimen magnetization with a selected spatial function and measuring changes in the phase of the magnetization. The spatial function is selectable to provide magnetization phase modulation corresponding to displacements in a selected direction, such as a radial or azimuthal direction. Methods and apparatus for producing images based on magnetization phase modulation acquire image data based on stimulated echos and stimulated anti-echos. In an embodiment, a series of 180 degree pulses produces alternating stimulated and stimulated anti-echos that are measured and assigned to respective images.
