The sub-millimeter bone pose tool for joint movements from biplanar videoradiography data.
XManager lets you manage subject information and all of the
system configurations, trials, and data files associated with it.
The most important function of XManager is to create, store, and load the
data associated with a subject.
XManager can then be used to launch any of the DSX applications in the DSX Suite with the subject information pre-loaded.
X4D tracks bones and implants in X-ray trials, using single-frame or 4D optimization.
The DSX algorithm
solves for the 3D pose by registering two non-coplanar X-ray images of a bone to two
digitally reconstructed radiographs (DRRs).
Visual3D was extended to integrate directly with X4D. The surface models and associated reference frames and regions of interest are loaded for additional kinematics processing and reporting.
To match DRR images to X-ray images, both sets of images are processed first. X-ray images are smoothed with a convolution filter, and then an edge detection algorithm is performed on them. The final processed X-ray image that is used for tracking is the edge detection image times a weighting factor, plus the smoothed intensity image. DRR images are not smoothed, but are input to the edge detection algorithm. The final processed DRR image is the edge detection image time a weighting factor, plus the original DRR image.
CalibrateDSX calculates the 3D configuration parameters of the X-ray hardware (the Pose of the X-ray sources and image planes) from images of a calibration object. It also uniformity-corrects, distortion-corrects, and resizes all X-ray image files.
Surface3D allows you to segment individual objects from CT data, create surface models of the objects,
and identify anatomical landmarks (e.g., ligament attachments). It uses 3D image data and creates tracking
objects (as voxel data) and surface models (as polygons) from voxel data. It allows the user to identify
anatomical landmarks that
are easily identifiable in image data and to get everything (CT, surface models,
landmarks, etc.) in the proper reference frames.
- Import DICOM files with CT data
- Use thresholding to label the voxels of the bone of interest
- Mask out the other voxels
- Crop the data
- Create a surface model
Note: For segmentation alone, alternative tools such as Mimics, ScanIP, and 3D-Slicer may also be used.
Orient3D prepares object surface models for tracking in X4D and kinematic analysis in Visual3D. It loads surface models and calculates anatomically meaningful reference frames and allows you to definelandmarks, and regions of interest, which are used to generate joint-distance maps.
Locate3D tracks points of interest (usually radiopaque beads) in X-ray image sequences.
PlanDSX (still in development) is a utility for designing the appropriate 3D configuration of the X-ray hardware for a specific subject and/or task.
DSX Suite costs $15,000 USD for a single license. Additional licenses
are $2,000 USD.
The Introductory offer is $12,500 for the initial suite and $1500 for each additional copy.
Web download only. When purchased, an on-line customer account is created and all software is downloaded over the Internet from c-motion.com. C-Motion accepts purchase orders, credit cards, bitcoin, wire transfers, and checks.
DSX is licensed per computer. Licenses are activated and deactivated locally and apply to the whole suite of applications.
DSX is a Windows application. It will run on a MAC only in a VM, like Parallels or VMWare where Windows has been installed. Be sure to turn off any hardware graphics accelerators in a MAC VM for OpenGL compatibility.
Yes, and it is free the first year. Maintaining support is $1250 USD per year. DSX support keeps the web download access for updates active, and allows access to C-Motion's world-class experts for biomechanics assistance.
No, DSX will continue to run without purchasing support, you just won't be able to get updates or research help.
A statement of C-Motion's support, user, and web access policies is available here.
A single installation file and license key are used by the entire lab. Each installed copy of the DSX Suite will activate its license over the Internet, limited to the number of licenses purchased. Licenses can be deactivated from the Help menu in XManager.
