摘要： 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.

摘要： An image signal captured by a monitor camera is input to an image processing device, displayed on a multiwindow display, and stored in a main storage device. A sound signal collected by a mike is input to a sound processing device, regenerated through a speaker, and stored in the main storage device. Process data transmitted from a process data controller are displayed on the display and stored in the main storage device. If an abnormal condition is detected in a monitored object, often the data stored in the main storage device before or after the abnormal condition has occurred are saved into a auxiliary storage device. When data are regenerate, the saved data are synchronized with each other while being regenerated on the display and through the speaker.
