Abstract

The present invention concerns a method and system for recording a monitoring log for use in a magnetic resonant imaging system, wherein a log document is crated and is shared in an external storage device, timed queries are made to monitoring points on a monitored target by a timer and the data collected are periodically reported to a control module; and wherein the control module formats the reported data into a record format and writes the record formed into the shared log document. When the log document is not accessible, a buffer queue is opened automatically in an internal storage device to buffer the reported data, and when the access returns to normal, the records and the recorded data in the buffer queue are written as a supplement into the log document.

Claims

1. A recording system for a monitoring log comprising:

a host computer;

a measurement and control module in data communication with the host computer;

a collecting module in data communication with the measurement and control module;

a channel switching device adapted to obtain data from a monitored target for entry into a monitoring log, said channel switching device being in data communication with said collecting module;

said measurement and control module and said collecting module forming a scanner that scans and collects, via said channel switching device, said data from said monitored target, and said measurement and control module communicating the collected data to said host computer;

said host computer having access to an external storage device, and said measurement and control module comprising an internal storage device, and said collecting module comprising a timer;

a portion of storage space in said external storage device being reserved for a log document, as said monitoring log, and said measurement and control module performing reading and writing operations relative to said log document, as a shared document with said host computer;

said timer of said collecting module making timed inquiries to monitoring points at said monitored target via respective channels of said channel switching device and periodically reporting data collected from said monitoring points to said measurement and control module, as reported data; and

said measurement and control module formatting said reported data into a report format and writing said reported data in said report format into the shared log document through said host computer, and if said measurement and control module temporarily cannot communicate with said host computer, said measurement and control module automatically opening a buffer queue in said internal storage device and buffering said reported data in said report format and, when said measurement and control module thereafter is able to communicate with said host computer, said measurement and control module automatically writing the reported data in said report format, currently in said buffer queue, into said log document, as a supplement, through said host computer.

2. A recording system as claimed in claim 1 when said channel switching device is adapted to interact with a magnetic resonance system, as said monitored target, and wherein said data from said measuring points are selected from the group consisting of system parameters and component statuses of said magnetic resonance imaging system.

3. A recording system as claimed in claim 1 wherein said collecting module, during scanning and collection of said data from said monitored target, operates said timer to automatically pause said timer, with no data being collected and reported from said monitored target while said timer is paused.

4. A recording system as claimed in claim 1 comprising a satellite station in communication with said host computer, said host computer providing access to said log document by said satellite station via said host computer.

5. A method for electronically recording a monitoring log, comprising the steps of:

in an external storage device at a host computer, establishing and sharing a log document;

making a plurality of timed queries to monitoring points of a monitored target through a timer, thereby obtaining collected data, and periodically electronically reporting said collected data to a control module;

in said control module, formatting said collected data into report data in a report format, and writing said report data in said report format from said control module into the shared log document through said host computer; and

if said log document is not accessible through said host computer by said control module, in said control module automatically opening a buffer queue and buffering said reported data in said report format, and when said control module subsequently obtains access to said shared log document through said host computer, said control module automatically writing the reported data in said report format in said buffer queue into said shared log document, as a supplement.

6. A method as claimed in claim 5 wherein the step of making timed queries to said monitoring points of said monitored target comprises monitoring respective points of a magnetic resonance imaging system, as said monitored target, and collecting data from said points selected from the group consisting of system parameters and component statuses.

7. A method as claimed in claim 5 comprising embodying said external storage device in said host computer.

8. A method as claimed in claim 7 comprising providing a communication connection between said host computer and a satellite station, and making said shared log document accessible to said satellite station via said host computer.

9. A method as claimed in claim 5 comprising embodying said timer in a collecting module in communication with said monitored target.

10. A method as claimed in claim 9 comprising, while said collecting module is collecting data from said monitored target, pausing said timer automatically and, while said timer is paused, not collecting data from said monitored target.
