Computed Tomography

7.7K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Purpose of the Study:

  • Introduce TRAKO, a novel data format for tractography datasets.
  • Enable immediate graphical and hardware-accelerated processing of streamline data.
  • Compare TRAKO's efficiency against existing tractography storage methods.

Main Methods:

  • Developed TRAKO based on the Graphics Layer Transmission Format (glTF).
  • Integrated advanced compression techniques for vertices, streamlines, and associated data.
  • Evaluated TRAKO on eight diverse tractography datasets.

Main Results:

  • TRAKO achieves significant data reduction, exceeding 28x.
  • Compression is lossless for statistical significance when replicating analyses.
  • Demonstrates efficient storage, transfer, and visualization capabilities.

Conclusions:

  • TRAKO offers a highly efficient solution for managing large-scale tractography data.
