Radia Automated QC Phantom Analysis » Radia FAQ

General

  • What is Radia?

    Radia is RIT's new diagnostic software for automated scoring and trending of image quality.

    Current modules support:

    • ACR CT and MR images from ACR Phantom
    • Catphan Phantom
    • Siemens Image Quality Phantom (used in radiation therapy)
    • EPID QC Phantom from PTW

    Radia allows the user to meet TG142 and insurance requirements and provides objective results for trending and tracking image quality.

  • What are the Radia Modules?

    Radia is built around a base module which all users must purchase. The base module includes a dicom viewer, dicom receiver, and an extensive tool box of features to view images and make measurements, as well as directory browsers and filters.

    Additional modules can then be purchased as needed. Currently there are three modules available:

    • The CT/MR ACR module,
    • Catphan/OBI Module,
    • PTW EPID QC Module
  • Can RIT WebEx into my computer for troubleshooting assistance?

    RIT does not have WebEx for troubleshooting however we now have Logmein Rescue. Logmein gives RIT technical support remote access to our customer sites as long as there is unrestricted internet access.

    Most often we can perform technical support over the phone or via email, but Logmein gives us the ability to see customer images, analyses and perform installations or upgrades to our software.

    RIT also uses OnConference as a method for software demos and recordings. Contact RIT Technical Support for more information.

Installation

  • What is Crypkey?

    Crypkey is a process and third party software tool that is used to activate the Radia software license. Site keys are generated using the crypkey license manager. At times, tech support may have to lead you through troubleshooting of your installation if your license file gets corrupted or if the crypkey service stops.

  • I get the message that my screen resolution and memory is not adequate.

    The Radia development team has tested various screen resolutions and we have found that 1280x1024 is the best screen resolution for viewing images in the Radia software. Also, a minimum of 1g ram is necessary to run the Radia software. If you are working with larger images, 1g may not be adequate.

  • I get the message "Program not authorized" when trying to open the Radia software.

    This message requires a site key from technical support to activate the software. If this message occurs, please check the following:

    • If this is a new version of Radia software, please email techsupport@radimage.com with the site code screen.
    • Someone has pressed the enter key after launching the Radia icon.
    • Users do not have read/write/execute privileges to c:\RIT\Radia\ and all folders, subfolders and files. Crypserv.exe and radia.exe should be excluded from virus software and startup checking
    • Reboot the computer prior to contacting technical support to see if the service can be restarted.
    • Site keys can ONLY be entered locally. Keys cannot be entered via remote desktop sessions.

     

  • What is the required computer configuration for Radia?
    • Intel Pentium-based or Centrino Duo computer (desktop or portable)
    • 1 GB Ram Minimum
    • Minimum hard disk space for installation: 1.1GB (After installation is complete, optional files may be removed reducing the required disk space to as little as 500 Mbytes)
    • CD Rom reader
    • Video graphics card and monitor capable of 1280 x 1024 minimum resolution and displaying 256 colors
    • Windows XP Professional 32 bit w/ Service pack 3, and Windows Vista Business Edition 32 bit

Features

  • How can I adjust Radia to reflect what I see visually?

    The parameters in the Radia software were developed by strictly following the ACR and manufacturer's recommendations for image analysis. The software was further adjusted to meet the visual results of an average of the results of individual independent examiners. Radia is designed to provide objective and repetitive results. With this in mind, the Radia developers wanted to account for user preferences. The preferences can be accessed by right clicking in the results area outside of the graph. See the user's manual for specific adjustments on each test. An example showing how to set the Preferences for MR can be seen in this Video: Set Preferences for MR Slices 8-11.

  • How can I use the Radia Dicom file filter?

    The Dicom file filter can be used to filter a Dicom directory by sorting by fields or by an exemplar image. RIT provides exemplar images that are examples of ideal images that can be used to search the directory for images that match this ideal image. The user can also choose to replace the RIT provided exemplar images with one of their own.

  • How do I use the "Write image to Dicom file" feature?

    The "Write image to Dicom file" feature allows the user to export an image and anonymize or remove all patient and facility information. The user can also select to save the current window and level settings or trim the edges of the image.

  • What image tools are available?

    There are tools available in the upper left corner of the image window for zooming, panning, viewing a square and circular ROI, and a measurement tool. Statistics of a measured line or a ROI are displayed. A profile through a line can be created by left clicking on the line. Statistics of this profile can be selected to be displayed. By right clicking in different windows the user can adjust the back ground color, print the panel, save the panel, adjust preferences, etc.

  • How do I add results to a trend analysis data base?

    Any time the user clicks on the "add to the trend analysis" icon the results will be added to the data base. These trended results can be viewed through the "File/Open Trend Analysis Data Base" menu option or through the shortcut key.
