Follow the steps below to acquire an image with a bead phantom:
Filename Function
Reconstruction.vxm
Parameter file used when reconstructing
objects
Reconstruction_Bead.vxm
Parameter file used for bead phantom
reconstruction
Reconstruction_GEO.vxm
Parameter file used when generating
geometry cal data
1. Place the bead phantom in a way that the side with longer empty spaces comes to the
buttom. The phantom consists of total 4 rows and 28 columns.
2. Angle.bin, RCP.bin, Uoffset.bin, and Voffset.bin files should always be present when setting
geometry.
3. If the incorrect file was created inside Angle.bin, RCP.bin, Uoffset.bin, and Voffset.bin, delet
all fthe file. If all files are correct, copy the create files from the
base para folder
and paste
them into the para folder .
4. Place the bead phamtom according to the instructions. Go to 2.5.2.1 if you are using a new
