The images were taken (a while ago) using a borrowed Nikon XT H 225 device and Perkin Elmer 0820 panel. I have received the images for research purposes from the image owner who stated, “images could be reconstructed with VGStudioMAX’s CT Reconstruction Add-on Module.” (I don’t own VGStudio) Also, the instructions stated “it is important to choose the correct Centre of Rotation (CoR), so that an accurate alignment of the axis of rotation of the turntable with the centre of the flat panel detector is achieved.” So I am looking for an ImageJ plugin that accepts axis of rotation data as part of the input.
I have tried polar-transformer (as Herbie suggested), but it does not allow the CoR to be specified, at least not as offsets. I have the following reconstruction info:
— start of info —
At z=0, CoR offset = -14
At z=+30, CoR=-12.75
Use these as regsitered offsets.
Top offset = -10.76
Bottom offset = -17.24
900x900x375 @ 0.175mm
Z-range of reconstruction from -5.81 to +59.81mm rel. to images.
— end of info —
Any ideas or direction would be most helpful. Obviously, I am attempting something I have little experience with, but I’m very willing to experiment.
