[Rtk-users] Short scan reconstruction problem - real projection images from Elekta XVI

[Yang Kyun Park]

Hi all,

 

I've been using RTK for a year and I appreciate for all the efforts being
made by the developers.

 

Even though I haven't had any problem with full scan images (360 degree
scan), I found that rtkfdk doesn't work well with my short scan images
obtained from our Elekta XVI system.

 

I've used a command line such as:

--geometry ElektaGeometry.xml --path his_file_dir --regexp ".*.his" --output
rtkfdk_short_scan.mha --spacing 0.5,0.5,0.5 --dimension 512,200,512 --origin
-127.9,29.5,-127.9 --hardware cuda

 

The reconstructed image looked very weird, like a distorted 3D volume with
very noisy patterns (as attached).

 

Note that I didn't change anything in the rtkfdk code and I believe that the
software is automatically recognize the short scan when it is loading the
geometry file(xml). (Please correct me if I was wrong.)

 

Thank you for your help in advance.
