Abstract

A method and computer system are provided for determining the performance of a computer system by determining at least one current performance value of the computer system in a current configuration. Processes being executed on the computer system during measurement of the performance value are determined. A comparison is made between the at least one current performance value and at least one reference value. In one example, the computer system includes a control computer and a medical assessment computer that are associated with at least one medical imaging system. The reference value may either be determined previously or it is determined in a method step by determining the performance value of the computer system in an original configuration.

Claims

1. A method for determining performance of a computer system, comprising the steps of:

determining at least one current performance value of the computer system in a current configuration to determine a current performance; and

comparing the at least one current performance value with a respective reference value.

2. A method as claimed in claim 1, wherein the computer system includes at least one of a control computer and a medical assessment computer respectively associated with a medical imaging system.

3. A method as claimed in claim 2, wherein said at least one of said control computer and said medical assessment computer includes both a control computer and a medical assessment computer, and wherein said current performance value is determined by measuring a data transfer rate between said control computer and said medical assessment computer.

4. A method as claimed in claim 1, wherein said computer system includes a data bank and wherein said current performance value is determined by measuring a data transfer rate between the computer system and the data bank.

5. A method as claimed in claim 1, further comprising the step of:

remotely controlling said method for determining performance remotely via an external network access to the computer system.

6. A method as claimed in claim 1, further comprising the step of:

defining a reference value prior to said step of determining the at least one current performance value.

7. A method as claimed in claim 6, wherein said reference value is an original performance value of the computer system in an original configuration.

8. A method as claimed in claim 1, further comprising the step of:

displaying an indication that a deviation between the current performance value and the reference value exceeds the predetermined threshold.

9. A method as claimed in claim 1, further comprising the step of:

deriving an overall performance value from a plurality of current performance values.

10. A method as claimed in claim 9, wherein said overall performance value is derived from a plurality of current performance values by averaging.

11. A method as claimed claim 10, wherein said averaging is a weighted average.

12. A method as claimed in claim 9, further comprising the step of comparing a current overall performance value with an overall reference value.

13. A method as claimed in claim 12, wherein said overall reference value is defined from a plurality of original performance values.

14. A method as claimed in claim 12, wherein an indication is displayed if a deviation between the overall performance value from the overall reference value exceeds a predetermined threshold.

15. A method as claimed in claim 1, further comprising the step of:

storing at least one current performance value.

16. A method as claimed in claim 15, further comprising the step of:

providing a performance value table for a plurality of current performance values.

17. A method as claimed in claim 16, further comprising the step of:

displaying graphically a temporal development of said at least one performance value by reference to the performance value table.

18. A method as claimed in claim 1, further comprising the step of:

determining at least one original performance value for respective processes executed on the computer system, and

storing said at least one original performance value.

19. A method as claimed in claim 1, wherein said comparing step takes into account processes being executed at a time of determination of the at least one current performance value relative to processes being executed upon measurement of said at least one respective reference value.

20. A computer program stored on a computer readable medium and executable on a computer, said computer program when executed performing the steps of:

determining a performance of a computer system using at least one current performance value of the computer system in a current configuration, and

comparing the at least one current performance value with at least one corresponding reference value.
