Volume Extractor Version 3.0 Operation ManualiForewords
In recent years, with rapid improvement in high speed computer performance, 3D image
that once could only be processed at work station has become accessible now. 3D image has
greatly extended its use from industry field to entertainment domain. Its application insimulation games and CAD is also being developed. In addition, 3D image reconstruction
with CT has been applied to mummy ruins of archeological discoveries and simulation ofgenerated cross-section for non-destructive inner examination. It can be said that 3D image
has been very active in every aspect of our daily life.
In medical field, 3D image in CT/MRI has been widely acknowledged and used. Image
diagnosis has been used for operation plan and informed consent. Even intermediate
hospitals have been equipped with CT/MRI and small dental departments have started using
CT. In addition, OCT has also been introduced into medical field. All of the above
mentioned needs to output a large amount of tomographic image data. In order to make fulluse of tomographic image data and make them much more visual, it is necessary to transfer
2D image group set into 3D image, so high-end workstation and professional software areindispensable.
Volume Extractor is designed for processing medical images. As long as Windows systems
are available, 3D reconstruction can be simply performed by inputting DICOM image.
Besides this, any specified part or crossed section can be viewed from a variety of angles
and used to generate real model with the help of PR apparatus for data output. The beginninguser of Volume Extractor is able to skillfully process 3D images and perform various
functions at simple operation guide.
Feel free to use simple and handy 3D image tool of Volume Extractor.

Both gradient and standard deviation are effective for edge detection.
The gradient extracts only pixels with large variation from the difference between the
pixel of interest and the adjacent pixel. The calculation formula of the threshold when
the number of pixels n and the difference in each axis direction is fx, fy, fz is shown.

For standard deviation, we extract only pixels with large standard deviation fromneighboring pixels of the target pixel. The calculation formula of the threshold when
the number of pixels n and arithmetic mean μ is shown.

In concept, point-based volume rendering is the same as [Volume Rendering] in 4.10.
However, displaying approaches are different. In point-based volume rendering, each Voxelis illustrated by cube points. But according to the date pitch, points toward Z position can be
automatically adjusted.

Specify color and brightness to display rendering results. (As shown in 4.11.1)

Figure 4.11.1 Rendering Result*4.11.1 Point adjustment towards Z position
In point rendering, voxel is displayed through cube points. Therefore, there is a huge
difference between the pitch towards X and Y position and the pitch towards Z position.
With such a big data difference, the points towards Z position can be possibly far fromeach other.
When inserting new points between other points (As shown in Figure 4.11.2), adjust the
new points so that no crack could appear in volume.

4.13.1.1 Function Outline
It can divide the overall brightness of volume data into several domains and make color
specification for each domain and display them in 3D image. The specified color can bereused again if saved. After inputting volume data, each brightness is seen as a domain
which is set between the minimum and maximum position. As for index image setting, refer
to Index Image in Chapter 6 [Various Setting].
Unlike volume rendering*4.13.1, the color of each slider is constant.
*4.13.1 Difference between volume rendering and index image
Volume rendering uses transparency and color for line insertion within thespecified domain while index image uses a specified color within the domain.
In index image, there is no concept like transparency, but there is only a choice
between Visible and Invisible.

importance means the model feature of polygon shape, and if the value is larger, it
represents the important characteristics of the polygon model. In [Reduction]function, in order to maintain model features, the polygon with lower weight ofimportance will be selected, and deleted firstly. When the polygons have the same
importance, the polygons will be deleted simultaneously. Therefore, it may bedifferent form the number of reduction targets (final target value).
