[Intl_DxMedPhys] Siemens MRI ACR protocol

[Gretchen Raterman Bell]

For what it's worth, I'll summarize some settings I've gotten from both the
DXlist and from Siemens that have helped tremendously.  I work on both
Aeras and Solas.

To improve signal uniformity:
- Use B1 filter
- Use sum of squares (coil combination)

To improve spatial resolution, particularly Solas:

   - Resolution tab à B1 Filter should be ON
   - Elliptical Filter should be OFF
   - Prescan Normalize should be ON
   - Sequence tab à Gradient Mode should be NORMAL or FAST
   - Sequence tab à RF pulse types, try different SAR settings (try this
   very last, he was unsure about this one)
   - If none of this improves the high contrast resolution, he highly
   recommended calling into the  1800 number for remote service:
      - In-Line Image Filter should be turned OFF
      - This is a global setting that only FSE or remote service can
      modify; must be turned back on after acquiring phantom images
      - It tends to be an overall smoothing filter
      - Particularly affects newer software, which is likely why we don’t
      see it on the Aeras


FYI, I haven't had to do that last bullet point yet, but good to know just
in case.
