[Insight-users] PixelType Doubt

[Daniela Sacchetto]

Hi everyone,

I'm writing because I have a question for you.

Could anyone explain me how can I decide the itk::PixelType? Usually I work with unsigned short pixels, but now I would like to understand better this problem.

 

For ex I know that:

 

PixelType must be "signed" for CT since Hounsfield units can be < 0.

 

Are there any rules for each medical image? (TC,PET,US,RX,...)

And when do you use pixelType = unsigned char?

 

Thanks all for your help,

Regards

Daniela
