There are already several Qt/ITK-based tools with this functionality. As far as I know, ROI selection in a lot of these is built on the VTK interaction primitives but there is no generic library for this sort of thing.<br>
<br>The ones below come to mind immediately as ITK-based and (various flavors of) open-source licensed so you can see what they do, or extend and contribute:<br><br>3D Slicer (BSD, v4 is Qt rewrite currently in beta)<br>Seg3D (MIT, v2 is very recently released rewrite using Qt and looks really nice in brief use)<br>
ITK-Snap (GPL)<br><br>MevisLab also has interaction primitives and ITK support, but the SDK is closed-source.<br><br>Several more here: <a href="http://en.wikipedia.org/wiki/List_of_open_source_healthcare_software#Imaging.2FVisualization">http://en.wikipedia.org/wiki/List_of_open_source_healthcare_software#Imaging.2FVisualization</a><br>

Dear all,<br>
<br>
I am developing an application for displaying and processing MRI<br>
images reconstructed from GE P-files.<br>
<br>
I would like, if at all possible, to be able to select regions of<br>
interest manually but I am not sure how to do this.<br>
<br>
I am developing the GUI in QT and I am just wondering are there any<br>
libraries I could use which would allow me to manually select ROIs in<br>
my QT based GUI as inputs for my ITK filters.<br>
<br>
Any suggestions would be much appreciated,<br>
<br>
Best Regards,<br>
<br>
Robert<br>
