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.

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.
