Hello I am newbie at RTK and tried to reconstruct 3D cbct dataset of a walnut( https://zenodo.org/record/6986012) using rtkfdk.exe but result was not good.
The script I used is: rtksimulatedgeometry --output="geometry.xml" --nproj=721 --arc=360.0 --sdd=553.74 --sid=230.66 rtkprojections --path "D:\CT projection\walnut" --output "projections.mha" --regexp .tif --newspacing 0.5 rtkfdk -p . -r projections.mha -o fdk.mha -g geometry.xml --spacing 0.05,0.05,0.05 --dimension=128,128,128 --neworigin -64.5,-64.5,0 Metadata describing the measurement geometry and settings for walnut projection dataset: [GENERAL] ProjectName=20201111_walnut_ Scanner=University of Helsinki Industrial Mathematics Computed Tomography Laboratory Measurers=Alexander Meaney Date=20201111 DateFormat=YYYYMMDD [GEOMETRY] GeometryType=Cone DistanceSourceDetector=553.74 DistanceSourceOrigin=210.66 DistanceUnit=mm [ACQUISITION] NumberImages=721 AngleFirst=0 AngleInterval=0.5 AngleLast=360 [DETECTOR] Detector=Hamamatsu Photonics C7942CA-22 DetectorType=EID Binning=1x1 PixelSize=0.050 PixelSizeUnit=mm ExposureTime=1000 ExposureTimeUnit=ms [XRAY] Tube=Oxford Instruments XTF5011 Target=Mo Voltage=40 VoltageUnit=kV Current=1.0 CurrentUnit=mA XRayFilter=None XRayFilterThickness=N/A XRayFilterThicknessUnit=mm The output data (fdk.mha) doesn't look very walnut when I open it in volview (https://volview.kitware.app/). Some of the parameters seem to be wrong, but I'm not sure where exactly the problem is. I would appreciate it if you could tell me how to solve the problem. Thank you in advance. Ansalsax
