Multi-Band Accelerated EPI Pulse Sequences

You are here

The multi-band accelerated EPI sequences developed at CMRR are now available for use at other institutions on compatible Siemens scanners by C2P agreement with CMRR and Siemens.

These sequences and the accompanying reconstructions are being actively developed as key components of the Human Connectome Project.

The available sequence variants and supported software versions are listed below. If you are interested in obtaining these sequences, the CMRR C2P instructions and agreement can be found on the web page of the University of Minnesota Office for Technology Commercialization. Once you have executed a C2P agreement and have been given an access password, the sequence binaries can be downloaded here by selecting the desired release number.

Note to users: If you have noticed a bug or have a request for a new feature in a future release, please open a new support request. Be sure to include the sequence version number (e.g. VB17A R006a), sequence variant (e.g. BOLD, diffusion), and the model of scanner you are using in the problem description.

Security concerns: The sequences and software are developed in a firewalled environment, the web server is regularly checked for network vulnerabilities, and the downloadable files here are regularly scanned for viruses. To detect unexpected changes, the downloads available here are regularly checked remotely against baseline checksums stored on the remote machine. Also, Siemens provides virus software for their scanners. You can confirm that you have downloaded a valid version correctly by comparing a md5sum of the downloaded file with these checksums.

Download Multi-Band EPI Remote Reconstruction Server:

An optional remote reconstruction server is available which allows for the possibility of dramatically improving the image reconstruction speed for demanding studies.

This is currently only available by special request.

A description of the setup with sample timing results is available.
