    • An arrangement in a magnetic resonance imaging apparatus for producing image data of an object being examined. The object is subjected to magnetic fields and RF pulse signals which produce echo signals. The echo signals which represent views of the object are detected. Data collecting circuitry selectively performs a data collection process on the detected echo signals to produce collected data such that, for those echo signals of a relatively small strength, part of the data collection process is suppressed and, for those echo signals of a relatively great strength, the data collection process is performed a plurality of times under identical operating conditions. A data processor processes the collected data to produce view data such that, for the echo signals for which the data collection process has been suppressed, interpolation data is produced and, for the echo signals for which the data collection process has been performed a plurality of times, a summing and averaging operation is performed on the collected data. The data processor combines the interpolation data with the summed and averaged data thereby producing view data. An image constructor performs a Fourier transform on the view data thereby constructing image data.

    • A path alarm processing method and device perform an alarm mask designation for an ADMIN_STATUS object of a GMPLS path message used upon path setup, and an alarm mask release designation for unused bits of a Sub-TLV object additionally generated. When an alarm generation and its recovery are recognized during alarm monitoring, the alarm mask release designation is confirmed to release an alarm mask. As the above-mentioned alarm mask release designation, at least any one of a lapse of a fixed time by a timer after a path setup, a predetermined message indicating an alarm mask release, and a predetermined number of receptions of the predetermined message can be designated.
    • 路径报警处理方法和设备对路径建立时使用的GMPLS路径消息的ADMIN_STATUS对象执行报警掩码指定,并且还附加生成Sub-TLV对象的未使用位的报警掩码释放指定。 在报警监视期间识别到报警生成及其恢复时,确认报警屏蔽释放指定以释放报警掩码。 作为上述警报掩膜释放指定,路径建立后的定时器经过了固定时间,指示警报掩蔽释放的预定消息和预定消息的预定次数的接收中的至少任一个可以是 指定
