Import of 3D CAD files into CIVA RT/CT: Volume loading order

3D CAD parts can be loaded into CIVA RT/CT. When volumes are nested within each other, care must be taken with the order in which they appear in the CIVA interface.

To ensure that CAD parts are correctly interpreted in CIVA and that the result is realistic, the internal volume must be loaded first.

 

 

 

To ensure that materials are correctly assigned, use the “Material” option available in the toolbox. By tracing a ray between the source and a detector pixel, you’ll be able to visualize the different materials passed through and their thicknesses, and thus ensure that the order of the different CAD files is correctly interpreted by CIVA.
