I’ve seen so far that I may use the JosephForwardProjectionImageFilter to perform the forward projection. I’ve also seen the test for this class but I don’t get it, where should i put my 2D slice as input to execute the transformation. About the back transformation with the JosephBackProjectionImageFilter I also need more information how I can use it to transform a sinogram back to a ct slice. There is a test at the documentation, but the link is missing there.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>I’ve got another independent question.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>Are some of you familiar with MITK and know how to get the superbuild up and running with RTK? I am writing a MITK-Plugin and want to reduce the metal artifacts before a segmentation. So if some of you have experience with the combination of RTK and MITK it would be nice if you will share it ;)<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>Best regards,<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>Tobias<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
