Method
The
Input
sequence defines the data to be reconstructed. If it is a multichannel sequence one or all
channels can be selected for the reconstruction.
Output
sets the name of the result image (sequence). If the sequence exists it is overwritten. Pressing the
button
New
will generate a new name (number). The size of the sequential images in
Output
is
determined by the size of the sequential images in
Input
.
Number of Views
determines the number of reconstructions which should be computed. The radio
buttons
Start
and
End
define which angle settings are currently shown. A definition for the angle
End
is
only necessary if
Number of Views
is higher than 1. If this is true the result sequence will get views from
the
Start
to the
End
angle definition. The other reconstructions are determined through the linearly
interpolated intermediate angles. The direction of view is determined from the angles as follows:
The angle
Angle Z
determines the rotation of the direction of view on the Z-axis. The angle
Angle Y
determines the rotation of the direction of view on the Y-axis that has been rotated by the angle
Angle Z
. The angle
Angle X
determines the rotation of the direction of view on an X-axis that is rotated
by
Angle Z
and
Angle Y
.
Channel
defines if the following parameters are valid for
All
or just for one. Defining the thresholds for
the channels independently is useful if the grey value boundaries of the objects differ too much in the
different channels. The thresholds
Grey Low
and
Grey High
define the grey value range of the objects.
The parameter
Aperture
is a measure of the size of the highlights. Small values generate large
highlights. Large values generate small highlights (similar to a spot).
Use the parameter
Reflection
to control the ratio of diffuse and reflective brightness components, i.e.,
the overall basic brightness compared with the highlights. When the value of
Reflection
is low, the
highlights predominate; when the values are high, the region appears to be uniformly illuminated and
the highlights are not so pronounced. When
Auto Update
is selected, the reconstruction is updated
automatically whenever a parameter is modified (except
Input, Output
, or
Number of Views
).
Show
Cube
defines whether a wire frame cube is shown in the
Display window
or not.
Application
This method can be applied, if the structures in the
Input
sequence can be segmented by grey value
thresholding. Because the gradient is calculated for every pixel, the
Output
appears in very fine detail.
Noisy
Input
sequences must be smoothed (function
Smooth
) before rendering, otherwise the surface
appears rough.
