Image Plot Dialog

Create 2-4 dimensional plots of images, create regions of interest, and
create classified images.
 |
Example Plotting 3 Images,
Creating ROI Image, and Classifying Images.
- Load a set
of eigenimages from the same location.
- Draw a
region of interest that covers the tissues to plot.
- Select Old-Style 3d
- Press Plot.
- Draw
regions of interest around visible clusters in the plot.
- Press
Fili.
- Press Multiple Roi Image.
- Press Classification
Image.

Dialog Items
 |
Plot
Press Plot to plot two or three images (or volumes)
against each other, mapping the result onto a 2-d plane. |
 |
Slice Plot
Press Slice Plot to plot three (or four) images (or
volumes) against each other by adding the x, y, (z) plots over a specified z
(or t) range into single slices. |
 |
3 2d Plots
Press 3-2d Plot to plot three images (or volumes)
against each other by plotting each combination of two against each other.
The three plots will appear in one image. |
 |
Exclude
Select Exclude to exclude the pixels from the X, Y,
and Z images that sum to the range defined by 1 += e.
 |
e
Enter a value, in e, to indicate the width
around 1 to use for determining the range. |
|
 |
Old-Style 3d
Press Old-Style 3d to select the fixed projection
style of plotting for the 3-dimensional plot. For increasing values, the x
axis is left to right, the y axis is bottom to top, and the z axis is
lower-left to upper-right.
Note
The Rotate option is disabled if this is selected. |
 |
Scale
The zoom factor
for enlarging or reducing the plot. By default these is calculated
automatically to fit the entire plot into the plotting region. A value of 1
scales an axis to cover 0 to the absolute extreme for 3-dimensional plots
and over the entire range for 2-dimensional plots.
 | Enter a zoom factor, in Scale X, for the
x-axis. |
 | Enter a zoom factor, in Scale Y, for the
y-axis. |
 | Enter a zoom factor, in Scale Z, for the
z-axis. |
 | Enter a zoom factor, in Scale T, for the
t-axis. |
|
 |
Minimums ad Maximums
 | Enter the minimum value, in Min X, to
plot from the X image. |
 | Enter the maximum value, in Max X, to
plot from the X image. |
 | Enter the minimum value, in Min Y, to
plot from the Y image. |
 | Enter the maximum value, in Max Y, to
plot from the Y image. |
 | Enter the minimum value, in Min Z, to
plot from the Z image. |
 | Enter the maximum value, in Max Z, to
plot from the Z image. |
|
 |
Rotate
Enter the amount
of rotation (angle) for each axis. The plot will be rotated and the 2d
projection will be displayed.
 | Enter the rotation, in Rotate X, for the
x axis. |
 | Enter the rotation, in Rotate Y, for the
y axis. |
 | Enter the rotation, in Rotate Z, for the
z axis. |
|
 |
Show Range on Plot
Press Show Range on Plot to create a rectangle (or
box for 3d) region of interest on the plot image that correspond to the x
pixel values, the y pixel values, (and the z pixel values for 3d) from the
plotted images. |
 |
Roi Image
Press Roi Image to create a binary image from the
original images, used to make the plot image, using the selected region of
interest over the plot image. A pixel in the binary image is assigned to 1
if that pixel contributed to the region of interest over the plot image. If
minimums and maximums are entered, only pixels from those ranges in the
original images will be considered.
Note
For the 3-2d plot, the binary image will contain only points
from the original images that plot to at least two of the three plots under
the selected regions of interest. |
 | Multiple Roi Image
Press Multiple Roi Image to create a multi-valued
image from the original images, used to make the plot image, using the
4-connected clusters from the selected region of interest over the plot
image. A single value is given to each cluster. Each pixel in the
multi-valued image is assigned to a cluster if that pixel contributed to
that cluster over the plot image. A contour map image of the clusters is
created with the corresponding pixel values from the roi image.
 |
Use Rectangles
Select Use Rectangles to take the first and last
point of the region of interest and create rectangles from those points to
cover the whole image. Use these rectangles as the clusters for creating
the multi-valued image. |
|
 |
Classification Image
Press Classification Image to create a classified
image from the multiple roi image, where each pixel is assigned to one of
the clusters by its Euclidean distance from the clusters' signatures over
the original images used to make the plot image. If the image is not a
multiple roi image, the current signatures are used.
