ExamCard description

This R3.2 Brain ExampleCard is designed for use with Achieva 3.0T TX with MultiTransmit.
New in R3.2 is MultiTransmit of the Brain. MultiTransmit of the brain can be performed in the 8ch SENSE Head coil, 8 and 16ch SENSE NeuroVascular coil, and the 32ch SENSE Head coil. This ExampleCard highlights the sequences that benefit the most from MultiTransmit technology.

Setting up the exam

When setting up your B1 calibration scan you need to have it at the level of the corpus callosum for whole brain imaging.


*Note: If you wanted to use MultiTransmit in the IAC's or orbits you need to run the B1 calibration in that area of interest.

MultiTransmit was introduced to reduce two shading artifacts seen in the front and back of the brain. Feel free to apply MultiTransmit to all of your brain protocols for ease of use.

Applying Multi Transmit:
If you want to use MultiTransmit with other sequences in the brain, all you have to do is go under the Geometry Tab and set MultiTransmit to "Yes".

RF Shims:
After you have turned on MultiTransmit you need to go under the Contrast tab and change RF Shims to "Adaptive"
