CSIP Level 1 Troubleshooting: All Troubleshooting Starts Here
- When does it happen: Time of day, during boot-up, during scan, image review, sending to
a network, during a calculation, during a measurement, playing/recording VCR, printing,
acquiring an image, annotating, other?
- How often does it happen: Intermittently, predictably, all of the time?
• Categorize/localize the problem:
- Is it a printing problem, an image quality or viewing problem, a data export or import
problem, or other?
- Consider if the symptom indicates an operating procedural error or a system failure. If it
is a system failure, determine whether it seems to be a hardware or software problem. If
it is a software problem, determine if it is an operating system or ultrasound problem.
• If possible, make hardcopy prints of the system displays that shows the first and subsequent
indications of the failure. Do this as soon as possible to ensure this type of data is not lost.
(Relevant data is often lost when the system is rebooted.)
• What, if anything, does the user do to recover from the problem?
Re-creating a
Problem
Successfully re-creating a problem that doesn’t damage the system can produce information that
is useful to troubleshooting and solution verification. But, before you try, be sure that you have
noted all the useful information you can. Before changing anything, consider if the attempt will
cause the loss of information or will change a circumstance that is better than re-creating the
problem. If you decide to attempt to re-create the problem, try to do so several times.
Isolating Causes
Remember that, sometimes, more than one cause can produce similar symptoms. Try to identify
as many causes for the given symptom as your experience and research allows and then priori-
tize them in order of most likely root cause of the problem. Attempt to eliminate them
one-by-one, staring with the most likely cause.
