With this method you can extract specific parts of the image of three-dimensional images. This is accomplished with three alternative projection planes, frontal in the XY direction, sagittal in YZ direction or transverse in XZ direction as seen from the observer of the image. You can choose between different projection methods. All methods have in common is that the pixels are analyzed by the observer along an imaginary projection beam. You can also determine the thickness of the projection planes, and thus the projection depth.

Parameter

Description

Projection Plane

Here you choose the type of the projection plane (Frontal (X/Y), Transverse (X/Z), Sagittal (Y/Z)).

Method

-

Maximum

Uses the brightest pixel along the projection beam.

-

Minimum

Uses the darkest pixel along the projection beam.

-

Average

Calculates the average of all pixels along the projection beam.

-

Weighted Average

This method is related to the calculation of the extended depth of focus. It prefers structures with more lateral sharpness along the projection beam. The output image contains more significant details.

-

Standard Deviation

Calculates the standard deviation of pixel grey values along the projection beam.

Start Position

Here you adjust the starting position of the project plane (in pixel units or z-stack positions depending on the chosen projection plane). The maximum range results automatically of the size of the input image.

Thickness

Here you adjust the thickness of the cutting plane (in pixel or z-stacks depending on the chosen projection plane). The maximum range results automatically of the size of the input image.
