[Rtk-users] 答复: About CR(Computed Radiography)

[商 宏杰]

Thanks Simon and Cyril,

I apoIogize for my confused question. I want to get a Radiofluoroscopic image rather than a Tomographic one from a phatom under certain angle. Is it possible to achieve this aim using RTK?

Hi,
If you mean Digitally Reconstructed Radiograph (DRR), this is what is called forward projection in RTK. See e.g.
http://wiki.openrtk.org/index.php/RTK/Scripts/ForwardProjection
RTK/Scripts/ForwardProjection - Openrtk<http://wiki.openrtk.org/index.php/RTK/Scripts/ForwardProjection>
wiki.openrtk.org
Note that the original file is in Hounsfield units which explains the negative values in the projection images since, e.g., the attenuation of air is -1000 HU.

Hi Sam,


I think you need to ask a more precise question. RTK is primarily a tomography toolkit, but contains some pre-processing methods that might suit your needs.

Can you describe what you are trying to do ?

Hi,

   Are there any classes of Computed Radiography in RTK? I do preciate if someone can give me some hints!
