View source for Example sequences @ 7T

__FORCETOC__

(This page is currently under development)

=Setup & hardware=
These example sequences are all readily available on our 7T scanner with the default "MultiX" setup:
* Scanner: Philips Achieva 7.0T
* Coil: Nova Medical 32 channel receive / 8 channel transmit head coil <br> <br>

The sequences can be found on the scanner console in the folder <to be added>.

=Basic parameters of example sequences=
This section lists the (acquired) resolution, echo time, repetition time, and scan time of the example sequences. <br>
==Structural==
* '''T1 MPRAGE:''' 0.8 mm isotropic, TE/TR = 3.3/12 ms, scan time = 5:50 (whole head) <br>
* '''3D FLAIR:''' 1.0×1.2×1.2 mm, TE/TR = 300/8000 ms, scan time = <ca. 5 mins> (whole head) <br>
* '''T2w TSE:''' 0.7 mm isotropic, TE/TR = 297/3200 ms, scan time = 10:24 (whole head, 2 averages) <br><br>

==Quantitative data==
* '''T1 map''' (MP2RAGE): 0.9 mm isotropic, TE/TR = 2.9/6.5 ms, scan time = 10:24 (whole head) <br>
* '''T2* map''' (ME-GRE): 0.8 mm isotropic, TE/TR = 3.0/31 ms, scan time = 4:57 (whole head) <br><br>

* '''TOF-MRA lenticulostriates''' (50 mm): 0.36×0.36×0.6 mm, TE/TR = 3.7/15 ms, scan time = 4:59 <br>
* '''SWI:''' 0.6×0.6×2.0 mm, TE/TR = 7.2/31 ms, scan time = 5:15 (whole brain) <br><br

==fMRI (BOLD)==
* TBA

==Diffusion MRI==
* TBA

=Reconstruction=
Most example sequences are automatically reconstructed on the scanner, and can be exported as DICOM or PAR/REC files (see [[DataExport]] for more information).  <br> <br>

Although the MP2RAGE T1 maps can be automatically reconstructed on the scanner using an MrCodeTools "PRIDE" tool, an offline Matlab reconstruction tool can be used to achieve more flexible reconstructions and signal masking. Likewise, a Matlab script is available for T2* map reconstruction. Please contact Thijs de Buck ([mailto:t.de.buck@spinozacentre.nl t.de.buck@spinozacentre.nl]) if you want to use the Matlab tools.
