Inobitec DICOM Viewer

Chapter 6. Segmentation


Functionality is available in the Pro edition

Segmentation is the division of an object into its component parts for ease of research and modeling.

Tasks that segmentation solves:

  • the researching of separate tissues parts with definite density range. Usually such parts have a complicated form and are hidden inside the other tissues, however it is impossible or difficult to highlight it with the cutting tools. E.g.: teeth and them roots, tumors, bones, vessels;
  • the calculation of the volume of tissue, such as tumors;
  • the study of mutual disposition of tissue that can not be visible simultaneously;
  • fusion segment and a full model to see its location within the tissue;
  • export of the structure surface for further use, such as 3D-printing;
  • import of objects that are used in the treatment to simulate their location in the tissues. E.g.: pedicle screws;
  • separation of tissues into separate fragments for convenience of perception.
  • cutting tissue by mask created from a segmented structure.

To solve these problems the Viewer allows you to build segmented structures both automatically and manually.

Segmentation of tissues is possible in the Volume Reconstruction window and Multiplanar Reconstructions window. In both modes you work with the same segmented structure (structures), thereby for its constraction you can use the advantages of both modes, switching between them.
