[Intl_DxMedPhys] mA Display Differences in Siemens Cios Alpha

[Wunderle, Kevin]

Hi Khalid,

Can you provide any additional information?

How much of a discrepancy? Is it potentially just a rounding difference or is it substantial?

Does this only happen during fluoroscopy, or do you see it during all modes of imaging? Note that in the acquisition mode some units may display mA during the acquiring of the image, but mAs on the screen afterward.

Kind regards,
Kevin

Dear All,

I hope this message finds you well.

I have noticed a discrepancy between the mA (tube current) values displayed on the Siemens Cios Alpha control panel and those shown on the screen. Since this difference can affect output calculations, I would appreciate any clarification on the reasons behind this variation.

Thank you all for your assistance.

Best regards,
Khalid
