Physio and IdeaCmdTool #327

Closed mharms closed 1 year ago

mharms commented 1 year ago

Given the ongoing issues with the Physio = DICOM option on XA30, a question has arisen about this bit of text in Multi-Band_C2P_Instructions.pdf:

Physio. recording: Control recording of physiological signals (cardiac, respiration, ECG, external) to text or encoded DICOM files. Text files will be stored in C:\MedCom\Log\Physio\ on the host computer (MRC). Legacy uses the classic CPmuSequence/IdeaCmdTool logging facility (this is the only option available on VAxx/VBxx systems and VD11x; it is known to be unreliable on VD11x/VD13x/VE11x). DICOM and File use the new online/ICE logging available since VD13A, which is recommended for use when available.

In particular, what was "unreliable" about the use of IdeaCmdTool on VD/VE, and do you know if that issue is still applicable to XA30? And was it the direct invocation of physio recording via IdeaCmdTool what was unreliable, or just its invocation within the sequence?

Speaking from personal experience using the IdeaCmdTool on a VE-11 system recordings would sometimes appear to start and we would get a flatline for the respiration or peripheral pulse channels. Other times the recording would be fine and then just stop half way through a scanning session/recording. Plus the default method records to the same named file, so if you do not copy out the file after a participant has been scanned the data will be overwritten.

Thanks.

Was that experience with using the Physio = Legacy option, or were you experiencing that behavior when invoking physio recording via IdeaCmdTool directly yourself?

BPaton commented 1 year ago

Via the cmdtool directly myself. Never used the legacy I I option. I would assume the issues were the same though given it is the tool/method that is the issue. Happy to be wrong of course.

IIRC since VD/VE the legacy option stops after 5 minutes or so. In detail I think it had to do with the way the legacy option tries to log all of the signals, but the system would timeout if some of the signals were missing (e.g. if you were not using the ECG at all it did not like attempting to log it). I did not have an option in the UI to just enable the relevant signals. The manual start/stop with ideacmdtool would work because you could manually turn on only the logs you needed. Or I could be remembering this wrong.

Anyway, I never bothered to dig into it further since the DICOM export was so much better. Of course that is currently not true in XA. But I will work on it, there will be an update in pre7. Follow up with #306
