Segmentation is the division of an object into its component parts to facilitate research and modelling.
The tasks that segmentation solves:
researching separate tissue parts with a certain density range. Usually, such parts have a complicated form and are hidden inside other tissues, hence it is impossible or diﬃcult to highlight them with the cutting tools, e.g.: teeth and thir roots, tumors, bones, vessels;
calculating the volume of tissue, such as tumors;
studing mutual disposition of tissues that can notbe visible simultaneously;
fusing a segment and a whole model to see its location within the tissue;
exporting the structure surface for further use, such as 3D-printing;
importing the objects used in the treatment to simulate their location in the tissues;
dividing tissues into separate fragments for better visualization.
cutting tissue by a mask created from a segmented structure.
To solve these problems, the DICOM Viewer allows you to build segmented structures both automatically and manually.
The segmentation of tissues is possible in the Volume Reconstruction window and the Multiplanar Reconstructions window. In both modes you work with the same segmented structure (structures), thereby for its/their construction you can use the beneﬁts of both modes, switching between them.
Fig. 6.1 illustrates the segmented root of a tooth hightlighted in yellow. Fig. 6.2 illustrates segmented kidneys highlighted in red and blue. The base volume is highlighted with the CLUT so that the bones can be seen best and the other organs are not visible.
