摘要： A magnetic resonance (MR) imaging system includes a magnet for producing a magnetic field to which a patient is subjected, a radio frequency (RF) transmitter coupled to a body coil within the magnet, an RF receiver coupled to a surface coil within the magnet and placed as close as possible to tissue being analyzed by the MR imaging system, and a computer controlled system for generating RF signals sent from the transmitter and detected by the receiver for use in producing nuclear excitation and corresponding detected induced currents in the surface coil sent to an analog-to-digital converter and then to the computer for processing into an image display of the tissue under analysis. A preferred embodiment of the invention comprises surface coil apparatus for use in analyzing tissue within a body cavity of the patient, and a preferred system for use in analyzing the tissue of the prostate gland includes an elongated hollow tube for transrectal insertion, and expandable balloon sealed to the exterior of the tube, and a loop antenna surface coil wire secured to the exterior wall of the balloon. Fluid pressure applied to the inside of the tube and then to the interior of the balloon expands the balloon and thereby expands opposite sides of the surface coil wire and holds the surface coil antenna in a spaced apart expanded position useful in serving as a means for obtaining high resolution imaging of prostatic tissue.

摘要： In one of many possible embodiments, a system includes a first reference node and a second reference node communicatively coupled to the first reference node by at least one network path, the reference nodes being configured to support transmission of a packet flow between one another over the network path. Each of the reference nodes is configured to count data packets received, the data packets being associated with the packet flow, and to latch a count of a number of the data packets received. The system includes a monitoring protocol configured to request the reference nodes to latch the respective counts. The monitoring protocol is further configured to retrieve the respective counts from the reference nodes and use the counts to determine a packet delivery measurement associated with the transmission of the packet flow between the reference nodes.

摘要： A device receives a list of uniform resource locators (URLs), selects a web page URL from the list of URLs, and requests, via a browser application, content corresponding to the selected web page URL. The device also receives, via a packet capture, a web page associated with the selected web page URL, derives performance information associated with the packet capture, parses the packet capture to extract page level statistics, connection level statistics, and inline object level statistics, and stores the page level statistics, the connection level statistics, and the inline object level statistics to output files.
