Phantom CT
A thorax CT was segmented into bone and soft
tissue, and converted to STL geometry files
suitable for the 3D printer.
Soft tissue was printed in Tango Plus (83 HU)
and bone in Vero White (136 HU). Lung cavities
were filled with sawdust (-795 HU).
A plastic model of a spherical tumour with a film
insert was mounted on a moving platform.
