Software package for realistic 3D visualization

All SkyScan scanners are equipped with a software package for realistic 3D visualization of scanned objects, the "CTvox" program. Current version supports export to mobile devices. A special software "CTvox for mobiles" allows volume rendering and manipulation on iPad/iPhone/iPodTouch.

Realistic 3D Visualization by Volume Rendering

The volume rendering program “CTvox” displays set of reconstructed slices as a realistic 3D object with intuitive navigation and manipulation of both object and camera, a flexible clipping tool to produce cut-away views, background selection including custom scenery and an interactive transfer function control to adjust colors and transparency. A "flight recorder" function allows fast creation of "fly around" and "fly through" animations based on the selection of several key frames with automatic interpolation in between. Imaging possibilities include lighting, shadows and stereo viewing.

CTvox for Mobile Devices

The CTvox app brings volume renderingto you mobile device. It is available for the iOS (iPad 2, iPhone 4, iPod Touch 4 and later, running iOS 5 and higher) and Android (Android 4.0 [Ice Cream Sandwich] and higher) platforms. The app is available free of charge through Apple’s App Store and the Google Play store.

Features of the app include:

  • Full-fledged transfer function editor
  • Saving & reloading of transfer functions
  • Transfer function files can be exchanged with the desktop version of CTvox
  • Multiple imaging modes (surface, MIP, attenuation)
  • Clipping/cutting box
  • Full in-app help

Volume data for the CTvox app is stored in a VXM file. A VXM file contains both the volume data and an associated transfer function. VXM files are generated using the desktop version of CTvox. After loading a dataset and editing the transfer function, select Export as VXM Data... from the Actions menu to create the VXM file: the volume data will be adequately resized and a snapshot of the transfer function will be included as well.

The easiest way to transfer a VXM file to your mobiles is to download it wirelessly using the device itself. Any method will do: through a web link, as an email attachment, using a cloud storage app such as Dropbox, Google Drive or SkyDrive. Opening the downloaded file will copy it to the CTvox app’s dedicated storage, then launch the app to open the dataset.

Alternatively, VXM files can be transferred over a USB connection (for iOS, iTunes is required.) This approach can prove more effective when multiple VXM files need to be transferred. For more details, please consult the manual or online help.

A set of example datasets is available here (this is a link to a Dropbox shared folder).
