Diffraction Enhanced X-ray Imagingcts that are almost completely free of scatter. They show dramatically improved contrast over standard imaging applied to the same phantoms. The contrast is based not only on attenuation but also the refraction and diffraction properties of the sample. The diffraction component and the apparent abso

Phase Contrast Imaging in the Field of Mammography overcomes this limitation. Up to now, however, all the applications of this technique required high radiation doses, raising several questions about its utilisation in medical radiology..The first low dose phase contrast X-ray images were obtained by the SYRMEP Collaboration at ELETTRA, the Trieste

Mammography Imaging Using a Harpicon-Based Image Detectorraphie imaging device. A mammographie image on the fluorescent screen is focused on the photoconductive layer of the high sensitivity HARPICON tube by lenses. The limiting spatial resolution in the 1024 × 980 pixel mode of the camera is about 60 um at an input field of 50 × 50 mm on the screen. Imag

Iodine-Filter Imaging System for Subtraction Angiography and Its Improvement by Fluorescent-Screen H an iodine filter for energy switching combined with an X-ray image intensifier. In vivo subtracted images of coronary arteries in dogs were obtained in the form of motion pictures. However, the image quality was not good for medical examinations because the contrast material was highly diluted. A n

Development of a Monochromatic X-ray Computed Tomography with Synchrotron Radiation for Functional Inal blood flow and metabolism of organs corresponding with their anatomical structures. The theoretical detectability of iodine contrast material is expected to be about 35 . iodine/g with 0.2-mm spatial resolution at a 1-mm slice thickness. However, the minimal detectable iodine concentration of th
