Abstract
The synchrotron radiation (SR) clinical mammography, using as detector a commercial screen-film system, is a further crucial step of the SYRMEP (Synchrotron Radiation for Medical Physics) Project. In March and April of this year, mammographic examinations on nine patients have been carried out with X-rays from ELETTRA, the SR laboratory in Trieste, Italy. The facility for Phase Contrast (PhC) SR mammography is now operative in patient mode and is used for patient examinations, producing breast images in different projections. The entire procedure is automated and is able to achieve the correct exposure on the film taking into consideration the requested limits on the applied dose, as a function of the thickness and glandularity of the breast. The SR mammography shows a higher spatial resolution and contrast detail visibility, in comparison with the conventional analog or digital mammography, with a comparable or lower dose. In some cases of these first nine patients, the radiologists have clarified the ambiguity of the previous examinations. These preliminary results are encouraging and a complete evaluation of the clinical impact of the new method is in progress.
