[Intl_DxMedPhys] Tests post gradient coil replacement for MRI

[Bob Kobistek]

With the Siemens service tool, you can also run an eddy current compensation test.

Subject: [Intl_DxMedPhys] Tests post gradient coil replacement for MRI

Dear all, One of our MR systems is having the gradient coil replaced (thankfully under contract) and I will be conducting physics testing after the install & calibration. I will run the ACR phantom and perform all standard measurements. 
Dear all,

One of our MR systems is having the gradient coil replaced (thankfully under contract) and I will be conducting physics testing after the install & calibration. I will run the ACR phantom and perform all standard measurements. I also plan to look through the service tool (Siemens Magnetom Aera, I have a service key) to examine the different gradient calibrations & tests that should be done post install. I may also re-run the Siemens phantom shim (field map) test to verify field homogeneity since they will have ramped down & then ramped up the system.

For the MR experts out there -- would you run anything else? Any other test result to pay special attention to or focus on?

Thanks, Steve
