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. <o:p></o:p></span></p>
