Hello,<br><br>I am blending CT images with SPECT (nuclear medicine) images. I have found and tried some settings of vtkLookupTable (rainbow, hot...) for colormapping those SPECT images, but none of them suits my needs. <br>
<br>I have one example of blending output of GE SPECT/low-dose CT Imaging system and it looks like that - <a href="http://goo.gl/8eDfH">http://goo.gl/8eDfH</a> (third column of images). That is the colormapping I am aiming for.<br>
<br>I tried to find some LUTs and it seems, that the closest is the FireIce (Hot/Cold) LUT, see the example here: <a href="http://goo.gl/KawPo">http://goo.gl/KawPo</a><br><br>I didn't find, how to set vtkLookupTable for creating LUT like that (SetHueRange,...). Could someone please help me, how to create LUT for colormapping like on that example (Hot/Cold)?<br>
<br>My second question comes with transparency - I don't know, if it's possible to colormap just bones (not black parts of image) and black parts make totally transparent, so when blending it would looks like just bones were colormapped?<br>
<br>Thanks for any suggestion!<br><br>Best regards,<br><br>Michal<br clear="all"><br>-- <br>S pozdravem Bc. Michal Srna<br><br>Fotografické portfolio:<br><a href="http://michalsrna.cz">http://michalsrna.cz</a><br>
