[Intl_DxMedPhys] OEC Elite field size issue [External_Email]

[Goode, Allen R. *HS]

Rebecca – thanks and yes, 100%. Your experience was exactly the same as ours, verbatim. I’m glad this is finally getting addressed for all of our patients.

Allen,

Thanks for posting this. I complained to OEC a couple of years ago when we got several of these units. They tried to deny there was an issue, saying that if it met the field restriction requirements in the diagonal directions then it was okay. They then questioned my measurement methodology. Finally, they told the hospital that they (OEC) had to send someone out to do extra work to meet the requirements of "their physicist" (i.e., me). I sent an inquiry to the FDA at the time - who verified that my interpretation of the regs was correct. I wouldn't call them out on this if they hadn't been so rude and patronizing about the whole thing.

I am honest enough to admit that I feel somewhat vindicated about the whole thing. The phrase "GE Healthcare has become aware of a non-conformance" also makes me laugh because they knew about this at least 2 years ago, and someone other than me likely pointed it out to them before that. Better late than never, I suppose!

Rebecca.

Listers-
In the past there were discussions on the list about collimation/field size failures for OEC C-arms. Over the past year, our hospital had several collimation failures on new GE/OEC Elite C-arms, during acceptance testing. Yesterday we received the attached product warning from GE/OEC on this very issue. Looks like GE/OEC will be replacing the “squircle” collimator on many units.

If you have OEC Elite C-arms, you may want to check if any are on the very long list to be replaced.
