The group’s activities was focused on the study of the potentiality of imaging sources thomson (TS) conducted in terms of visibility of details in images of Phase Contrast (PC) and of Phase Retrieval (PRI) compared to the detail visibility in absorption images. In fact it has been developed a new method of analytical/numerical, called Combined Mixed Approach (CMA), for the reconstruction of phase maps from X-ray images. The PRI allows a quantitative approach because the map phase is directly proportional to the electron density of the object and can, therefore, access to essential information of the internal structures of objects/tissues. Some preliminary experiments were done at synchrotron sources, with different samples, showing significant increases in image quality compared to X-ray absorption imaging.
