The GUI
This is the current GUI of the plugin (release 2.1.0).
The left column contains a command panel with some buttons to control the plugin, a text panel
to show some useful info about the ROI and a histogram of the Roi values.

8bit color mode
It's possible to load image using the 8bit color mode.

image sequences
It's possible to load image sequences and work on every single image.

Comparison with other image programs:
Selecting a lymphoma with Photoshop by Adobe
As it can be seen from the screenshot on the right, Photoshop wand can select the region with a certain
degree of approximation but, in the ROI there are also parts that belong to different organs.

|
|
Selecting a lymphoma with Gimp
Gimp provides a better approximation of the region with respect to Photoshop, but parts of ROI are
missing.

Selecting a lymphoma with Yawi 2D for ImageJ The selection isn't just
visually better and easier to obtain that the previous two, it is also more
precise. In fact only in this case we could discriminate the left psoas
muscle from the tumor.
Lymphomas, among tumoral lesions, have the most variable geometry and are
the most difficult to distinguish from the surroanding anatomic structures.
It enables and simplifies the selection of a tumoral region on each slice of
a CT analysis, and computes the volume of the selected region.
Volume measurements can be used to better understand the course of the
illness, providing a forecast on its alterations and permitting quantitative
evaluation of the total mass and of its modification after teraphy, wich is
useful either in clinical and research settings.

Smooth algorithms:
We have implemented two algorithms for smoothing generated ROIs.
In this image you can see how a generate ROI (left image) is smoothed by the first algorithm (center image)
and then by the second one (right image).
