Hi, I have 20 projections of a target and I would like to understand what can I do wrong because my result is bad.
So, here are the parameters of the system: - SID: 83.9 cm - SDD: 131.0 cm - SourceOffsetY: 1.42 cm - SourceOffsetX: 1.42 cm - DetectorOffsetY: -1.07 cm - DetectorOffsetX: -1.07 cm - Gantry Angle: depends on the particular projection. The detector is a Mercu1717V. Pixel matrix is 3072x3072, the detector effective area is: 427.008×427.008mm I ran these commands: rtksimulatedgeometry.exe -o geometry.xml -f 0 -n 20 --sdd 1310 --sid=839 --proj_iso_x=0 --proj_iso_y=0 --source_x=0 --source_y=0 rtkfdk -g geometry.xml -p ./dcm -r .*.dcm -o fdk.mha --hann 0.5 --pad 1.0 --verbose and the result is: https://gyazo.com/1aec04c1be241e39c483e208ded2bc86 The proj_iso_* and source_* parameters are 0 because I got an error with the values above. I'm new in the RTK and CBCT world so I have to learn a lot of these things. Thank you for any help! Regards, Attila Nagy Spinotron Magyar Sugársebészeti Innováció Kft. - http://www.spinotron.hu/
