Visualize, explore, and quantify with best in class rendering

Dragonfly Pro from Object Research Systems (ORS) is an advanced analysis software solution for 2D/3D data acquired by a variety of imaging technologies including X-ray microscopy and FIB-SEM. Using state-of-the-art volume rendering and access to advanced visualization techniques, Dragonfly Pro enables high-definition exploration into the details and properties of 3D datasets. Interactive inspection with color and opacity mapping means that in-depth analyses can always be visualized in meaningful ways and findings can be presented with easy-to-produce high-quality animated sequences.​

Multi-scale and multi-modal data visualization​

With Dragonfly Pro, file formats such as .txm and .czi can be read and include system spatial coordinates allowing for accurate dataset registration used in Scout and Scan and correlative workflows. Combined with data handling for time-dependent, 4D data.​

Customize with Python scripting

Dragonfly Pro enables Python scripting - a powerful feature that allows users to customize their data processing and visualization needs. Users now have access to the data channels and properties within the interface creating a limitless and customizable post-processing environment. In addition, Dragonfly Pro uses Python with numpy, scipy and many other libraries standard with Anaconda distribution.​

Easy to use

Dragonfly Pro is easy to use. With minutes of experience, you can explore, navigate, and annotate your dataset. In a few hours, gain control of more advanced tools such as image processing, segmentation, object analysis, and movie making. Use our compact, topic-specific training videos to familiarize yourself with Dragonfly Pro in the shortest amount of time.​ ​

    Deep Learning module

    ​ Harness the power of convolutional neural networks, realized through cutting edge artificial intelligence engines to advance your image processing results to new levels.​

    ​ Powered by Google’s TensorFlow and Keras, Dragonfly Pro gives users the power to develop new neural networks, but also to train, reuse, and repurpose existing models for advanced applications that will revolutionize your workflows.​

    ​ Dragonfly Pro’s trained neural networks behave like image filters, this makes them easy to preview, fast to apply, and simple to share for reuse. Dragonfly Pro’s Deep Learning solution is bundled with pre-built and pre-trained neural networks, implementing such powerful solutions as UNet, DenseNet, FusionNet and many others. ​

    ​ The latest version release features a number of enhancements for Dragonfly Pro's ground-breaking Deep Learning Module, including support for multiple channel inputs, elastic deformation on patches, training data statistics, a model evaluation tool, and much more.​

    License Activation

    How do I activate Dragonfly Pro license?
    After installing Dragonfly Pro, go to Help menu and select Activate Product. Enter your license key in the Activation Key text field. Click Activate.

    How do I activate Dragonfly Pro license if my workstation is not connected to internet?
    You can request an offline (pre-activated) license key by contacting [email protected] . In the request, please provide Dragonfly Pro license key and Computer ID (can be found by running Dragonfly Pro, go to Help > Activate Product).

    Can I use Dragonfly Pro license on two workstations? 
    No, Dragonfly Pro license key is node-locked and can only be used in one workstation.

    ​ Dragonfly Pro Software Update

    ​ Am I entitled to the latest version of Dragonfly Pro version on my workstation?
    All customers are entitled to the latest version of Dragonfly Pro that is released within one year of license activation or six months after purchase date, whichever is earlier. Beyond that, an active Annual Maintenance Contract is required to allow the download of latest version of Dragonfly Pro. To inquire about extending your expired Annual Maintenance Contract, please contact [email protected].

    ​Annual Maintenance Contract ​

    Do you offer Maintenance Contract? 
    Yes. Each Dragonfly Pro license purchase comes with one year of maintenance contract. Owners of a maintenance contract are entitled to free upgrades of minor and major software releases, as well as to priority Technical Support services over a period of 12 months from the date of initial purchase. Additional coverage can be purchased after the first year. ​

    ​Visual SI Advanced existing customers ​ ​

    As an existing Visual SI Advanced customer, do I have access to Dragonfly Pro? 
    Existing Visual SI Advanced Customers have complimentary access to the initial version of Dragonfly Pro. Both software packages will run independently on your Visual SI Advanced workstation as you make your transition to Dragonfly Pro. Keep your Visual SI Advanced software running as long as you like, it is a perpetual license. However, all feature improvements and continued development will be performed on Dragonfly Pro. We encourage you to transition and be part of its Python functionality and growing user community! ​

    ​ As an existing user, getting started is simple: ​

    Download the Dragonfly Pro trial installer from this website onto the workstation that runs your activated version of Visual SI Advanced.​
    Upon installation, the Dragonfly Pro software will activate via your existing license key. ​
    Be sure to view the newly-produced Dragonfly Pro training videos. All topics from Visual SI Advanced have been reworked in the Dragonfly Pro interface. There are additional training videos available that showcase new features that Dragonfly Pro has to offer. Please begin with the  Quick Start Basic Training.​

    I'm an existing VSI Advanced customer without a current annual maintenance contract. Can I still get Dragonfly Pro? ​
    Yes, regardless of where you stand with your annual maintenance contract, you have complimentary access to the initial version of Dragonfly Pro. This does not reactivate or extend the terms of your maintenance contract.

    ​ Do I need to upgrade my workstation to support Dragonfly Pro? ​ ​
    ​ No, Dragonfly Pro will run on your existing Visual SI Advanced workstation with dedicated professional  graphics. Please note that Dragonfly Pro is not supported by integrated laptop graphics. ​

    ​ Do I have to run Dragonfly Pro on the same workstation that runs Visual SI Advanced?  ​
    ​ Yes, Dragonfly Pro must be run on the same workstation as you are currently running Visual SI Advanced. If  you need to transfer to another workstation, transfer both software through the activation/deactivation  process.   ​
