7TQA

7T QA procedure

The QA procedure contains several steps. Make sure there is no patch activated while doing them.

1) MR signal stability and RF transmit test

2) EPI stability

3) SPT batches

MR signal stability and RF transmit test

The goal of the test is to show stable performance using the Dual 1H TR interface box with the Nova volume TR coil and the receive interface boxes with the Nova 32 channel array insert. Or in case of MTX8 the Nova TX8 Rx32 coil. If the results are stable the system can be used for sensitive scanning like fMRI.

Duration:

Classic: 12 minutes including 1-time repositioning (excluding building setup)

MTX8: 25 minutes including 1-time repositioning (excluding building setup)

How to run:

Before starting make sure that:

• The system is fully calibrated
• No patch is loaded
• Application software isn't running

Classic setup: Build the setup using the next coils and interface boxes. Use the wooden phantom holder with the blue 10cm sphere to position the phantom. Move the setup to iso center.

MTX8 setup: Build the setup using the Nova TX8RX32 coil. Use the wooden phantom holder with the blue 10 cm sphere to position the phantom. Move the setup to iso center.
