[Rtk-users] loading projection images for sart

[Robert Calließ]

Hello,

I got compiled the ITK and RTK with help of cmake. I also had a look

at the examples coming with RTK. I want to run a simple SART and 

got projection images in the format PNG and BMP.

 

So I create an instance of the ThreeDcircularProjectionGeometry, SARTConeBeamReconstructionFilter 

and add the geometric projection data.

 

rtk::ThreeDCircularProjectionGeometry::Pointer geometry;

geometry = rtk::ThreeDCircularProjectionGeometry::New();

geometry->AddProjection(……)

 

rtk::SARTConeBeamReconstructionFilter<OutputImageType>::Pointer sart = rtk::SARTConeBeamReconstructionFilter< OutputImageType >::New();

 

How to add a stack of images to the SART reconstruction, i.e. std::vector<itk::Image::Pointer> images ?

I got xray projections in png format.

 

There is a method in the SART class called SetInput. But according tot he examples it is used to set a volume.

 

Does anybody alread wrote a small piece of code that loads some images from the disk and put them into the SART reconstruction ?

 

Regards,

Robert
