Energetic heavy particles from an accelerator mnay be used to produce radiographs with high contrast and high depth resolution. Small differences in the stopping power of objects can be detected and permnanently recorded by using stacks of plastic track detectors. This method should aid in the diagnosis of soft-tissue abnormalities, including some tumnors, and make possible quantitative reconstruction of the internal density structure of objects.
