Clients

 Client Overview

To perform offline reconstructions with Yarra (or to collect workflow information), it is necessary to install a client software, which transfers the measurement data to the YarraServer. The Yarra client package comes with three different client programs (executables), which each have a different application:

 
Icon Filename Client Name Purpose
ORT.exe Offline Reconstruction Task Submission of acquired scans for offline reconstruction from Siemens MRI systems.
SAC.exe Stand-Alone Client Submission of saved raw-data files (Twix) for retrospective offline reconstruction from stand-alone workstations.
RDS.exe Raw Data Storage Background service for Siemens MRI systems to automatically collect raw-data files (Twix) and store them on a network share or disk drive. In addition, RDS allows collection of workflow information (in combination with Yarra LogServer).
 

The ORT client is the program that should be used if reconstruction tasks need to be submitted directly from the MRI systems (e.g., by the techs after the scan has been completed). This would be the case, for example, if a new reconstruction technique should be evaluated as part of routine scans. If the measurement data (rawdata) of scans should only be collected but not reconstructed automatically, this can be achieved using the RDS client. The RDS client runs invisible in the background on the host computer of the MRI system and will store the requested data on a network drive at night (or at another configurable time). This can be very helpful to collect a collection of measurement data from clinical routine scans. If these saved measurements files should be reconstructed at a later time, this can be done with the SAC client. The SAC client is normally used on external workstation PCs and not on the MRI systems. A typical use-case would be if a researcher wants to reconstruct a single dataset using different reconstruction algorithms or settings.

All three clients are contained in the Yarra client package that can be downloaded here. Installation instructions can be found here.

Currently, the following software versions of Syngo MR are supported:
VB13A VB15A VB17A VB19A VB19B VB18P VB20P VD11A VD11D VD13A VD13B VD13C VD13D VE11A VE11B VE11C VE11D VE11E VE11P VE11S VE11U VE12U XA10A XA11A XA11B XA20A XA20B XA30A XA31A XA40A XA50A

Certificates

To run the Yarra client on scanner versions XA10, XA11A, XA11B (e.g., MAGNETOM Vida or Sola), it is necessary to install software certificates before the client can be launched. Please contact us to obtain these certificates.

Alternatively to installing the ORT client as executable on the MR system, it is also possible to use the YarraLink sequence, which may circumvent regulatory issues related to installing application executables on a Siemens MR system.
