[Insight-users] Problem to create RGB images

[Alfonso Castro Martinez]

We are using ITK 3.0.2 in linux to manipulate CTs in DICOM of lung 
nodules from LIDC. In this database each CT serie has associated a XML 
file with information about the position of the nodules and other 
information about them.

We are developing an application to read each XML file and it shows the 
nodules in each CT in different colours depending about information of 
the nodule. We are trying to create RGB images using the itk::RGBPixel.

The problem is we want to conserve the Hounsfield units in the CT, 
however we can't be able to make it because the values of the pixels 
must be unsigned char or unsigned short int.

Are there some method in ITK to create a RGB image with the Hounsfield 
units?

Thanks.
