Low energy X-rays from a Mammography system were used to capture small differences in inherent tissue contrast in two-dimensional images of cut samples of select fruit and vegetable models avoiding excessive volume averaging. High spatial resolution CT images were also acquired of whole fruits to avoid volume averaging to help detect low tissue contrast. A limitation of CT imaging is the high kVp unavoidable in CT that lowers tissue contrast while the advantages are that of non-invasive 3D visualization. Using these two approaches that are very different in physical principles it is not known if either one could display possible displacement of diffusion of endogenous minerals in fresh fruits during thermal stress from the heat shocks and during interaction with exogenous radiological contrast media. This project will compare benefits of high spatial resolution in CT with the high contrast details present in Mammography.
