<p class=MsoNormal>Hello everyone,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am working on developing a simple medical image segmentation
program, which provide interactive selection and automatic saving function of multiple
seed points. That means when left-clicking on one of the CT slices, the 3D position
of that point will be automatically saved to the code. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I applied ImagePlaneWidget to pick the position of certain
clicked point. The position and intensity value can be shown on the screen. But
I have no idea how to program to save the position to the code. Could you give
me a hand about how to solve this problem?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Here is the code of ImagePlaneWidget:<o:p></o:p></p>
