I have tested the reconstruction speed with both head coils. Our protocol is similar to "LSCMRR_3T_printout_2014.08.15", similar matrix, voxel size, slice, and TR, etc. The reconstruction speed is 1.1s per volume for 64CH and 0.9s for 32CH, which are slower than TR(0.73s). We just have a chance to upgrade our SIEMENS Prisma from VD13D to VE11C which was recommended by SIEMENS, and we will upgrade the reconstruction computer at the same time. SIEMENS provide us two kinds of MR workplace as follows (image reconstruction computer), standard and high-end, respectively. I would like to know which kind of recontruction workplace as follows are you using? If neither, did you modify the reconstruction computer yourselves? I would be very grateful if I can have more detail information about your prisma reconstruction specifications, so that we can compare and decide what kind of MR workplace is suitable for us to run HCP style protocol. A. The standard Computer HW upgrade kit for the syngo MR Workplace includes: 1. a syngo MR Workplace with 1 x Intel Xeon Quad Core CPU / 3.6 GHz, 8 GB RAM, 2. one 300 GB system hard disk, 3. one 300 GB hard disk for image data and 4. one CD-R/DVD-R drive for image storage. B. The high-end image reconstruction computer has the following specifications: ≥ 2x Intel W5690 (hexacore) processors 3.46 GHz ≥ 128 GB Main Memory (RAM) ≥ 750 GB Hard disk for raw data ≥ 100 GB Hard disk for system software Tesla GPGPU By the way, the following is the acquisition workplace offered by SIEMENS. I would like to know if it is OK for HCP style acquisition? Thanks a looooot! The Computer HW upgrade kit for the syngo Acquisition Workplace includes: 1. a syngo Acquisition Workplace with 1 x Intel Xeon Quad Core CPU / 3.6 GHz, 32 GB RAM, 2. one 300 GB system hard disk, 3. one 300 GB hard disk for database, 4. one 300 GB hard disk for image data and 5. one CD-R/DVD-R drive for image storage, Any relevant information and idea would help a lot. Thank you very much! Looking forward to your reply. -- Meizhen Han PhD Candidate Center for MRI Research Peking University Beijing, China At 2017-07-01 00:03:22, "Harms, Michael" <mha...@wustl.edu<mailto:mha...@wustl.edu>> wrote: We have a more recent (and importable) protocol available here that I would suggest you use as a starting point: http://protocols.humanconnectome.org/CCF/ Your Prisma should already come with GPUs. Are you using the 64 channel coil? That will be a slower recon than the 32 ch coil, but I believe the recon still shouldn’t get too far behind even with the 64 ch coil. Try importing the VD13D version of the protocol available above, and compare the recon times for both the 32 and 64 ch coils, if you have both available. cheers, -MH -- Michael Harms, Ph.D. ----------------------------------------------------------- Conte Center for the Neuroscience of Mental Disorders Washington University School of Medicine Department of Psychiatry, Box 8134 660 South Euclid Ave. Tel: 314-747-6173 St. Louis, MO 63110 Email: mha...@wustl.edu<mailto:mha...@wustl.edu> From: <hcp-users-boun...@humanconnectome.org<mailto:hcp-users-boun...@humanconnectome.org>> on behalf of "Glasser, Matthew" <glass...@wustl.edu<mailto:glass...@wustl.edu>> Date: Friday, June 30, 2017 at 5:52 AM To: HMZ <hmz...@163.com<mailto:hmz...@163.com>>, "hcp-users@humanconnectome.org<mailto:hcp-users@humanconnectome.org>" <hcp-users@humanconnectome.org<mailto:hcp-users@humanconnectome.org>> Cc: 葛鉴桥 <g...@pku.edu.cn<mailto:g...@pku.edu.cn>>, 周思中 <zhou.sizh...@163.com<mailto:zhou.sizh...@163.com>> Subject: Re: [HCP-Users] Questions about reconstruction speed of Multi-band EPI sequence in LSCMRR I believe we use GPUs to speed this up.

I'm writing for seeking a solution for the problem we encountered during the application of HCP MRI sequence on our recent research. We tried a similar protocol as "LSCMRR_3T_printout_2014.08.15" on our prisma (software format is VD13D), while the reconstruction is quite slow. When several continuous Multi-band EPI are used, if the former Multi-band EPI hasn't started to reconstruct and the latter sequence is ready to go, the reconstruction of the former sequence will be skipped with an error message (Something like “Image reconstruction is failed.” ) I noticed the software format of prisma in CMRR is also VD13D, so I'm wondering whether you have encountered this kind of reconstruction problem. If yes, how did you deal with it? If no, what is the speed of your reconstruction computer andcan we have the model type of it, so that we can compare and improve ours. Any relevant information and idea would help a lot. Thank you very much!
