2 Software Installation Procedure
2.1 Installation
The sequence consists of 5 files. The sequence file for the host, the sequence file for
the MPCU and the ICE (EVA) program.
Copy the sequence .dll-file for the host to the customer sequence directory:
copy os_mepi2d_VA21.dll %CustomerSeq% (\n4\x86\prod\bin\)
Copy the sequence file for the MPCU to the corresponding sequence directory:
copy os_mepi2d_VA21.m750 \n4\ppc750\prod\bin
!!Attention!! This is only correct for systems with Reco-PC and m750 MPCU!
Otherwise, copy the relevant MPCU file to the corresponding directory. Software
does not run on Alpha reconstruction machines.
CoilSelectManipulator.h ist ein noch fehlendes File in
C.\idea\n4\comp\Measurement\CCSpuSer\CoilInterface.
Copy the EVA program .dll-files to the customer EVA directory:
copy MotionCorrDecorator.dll q:\bin
copy MosaicDecorator.dll q:\bin
Copy the EVA protocol :
copy t-test_10B10A_moco_mepi.evp
C:\MedCom\MRICustomer\EvaDefProt\Bold
Create a new default protocol:
Open the Exam Explorer, select a Protocol location, select 'Insert ... Sequence',
select 'Folder: USER', select 'os_mepi2d_VA21', click 'Insert'.
Double click the new protocol and adjust the parameters as desired.
The first two and the last steps have to be repeated for the os_mepi2d_pace_VA21
sequence for prospective motion correction.
