Once you have successfully registered to use Trial Wire, log in and click on the start button to access the configuration page. Prior to using Trial Wire you need to take a moment to ensure Trial Wire is configured to your needs. There are a number of settings that need to be entered depending on what function you wish to perform on the data.

The configuration file can be saved so you do not need to re-enter this information prior to each use. You can, of course, change the configuration options if you want.

Configuring Trial Wire

1.    Select Transfer Type

FTPS Server Configuration: Files are transferred to the specified FTP server

Enter the host and port details and the destination directory on the server side. Note that the Username and Password information required to connect to the FTP site is not stored centrally and needs to be entered prior to the actual transfer taking place. It will need to be re-entered prior to each transfer. Please contact your IT administrator to obtain FTP host and port details.

Local Configuration: Files can be moved to another directory on the same computer

You can use Trial Wire for organizing or de-identifying files that you want to keep on the same computer, write onto your file server or send to a removable device like a USB stick.  If you select the local transfer option, a local destination directory can be selected, e.g. c:\data for Windows users.  The specified directory will be created if it does not exist (but the drive letter must be valid on that machine).

 2.    DICOM Header De-identification

Select the options you want to be reflected in the transferred DICOM data. The following fields in the DICOM header can be automatically set to “de-identified” or manually edited to take any value:

• Patient’s Name
• Patient ID

The Patient’s Date of Birth can be set to:

• Remove all day/month/year information by changing to a fixed value 01011901
• Remove day/month information but retain year, e.g. 0101YYYY

As an option you can also choose to bulk de-identify a number of other fields that may contain identifying information.

A list of modified fields will be displayed prior to transfer.

 3.    Select File Structure in Destination Directory

There are three file structure options

Option One - Impose structure Subject/Study/Series:
The directory structure is derived from DICOM headers such that the directory structure below the target location is -/-/-.

The Subject directory name is generated from the combination of the Patient ID and Patient Name DICOM tags. The values used are those after de-identification. For example, if the Patient ID is 1234 and the Patient Name is John Smith, and if Trial Wire is configured to set Patient Name to "De-identified" and to leave Patient ID the same, then the Subject directory name will be 1234-DE-IDENTIFIED. 

Option Two - Flat directory with DICOMDIR:
All files are written to the target location, without any directory structure being created; the files are renamed such that they have unique 8-character filenames (A-Z, a-z, 0-9 and _ are acceptable characters) and a DICOMDIR file is created to describe them.

Option Three- Mirror the original structure:
The directory structure below the target location will be the same as the directory structure below the source location (directory trees that do not contain any DICOM files will not be replicated). Before using this option you should check that the original structure doesn't contain any patient identifiable information in the directory names, as, this option does not perform any de-identification on the directory names.
