Abstract


The present work synthesizes the experimental results obtained in the
characterization of 64 microstrips crystalline silicon detector designed for
experiments in high energies physics, with the objective of studying its
possible application in advanced medical radiography, specifically in
digital mammography and angiography. The research includes the acquisition
of two-dimensional radiography of a mammography phantom using the scanning
method, and its comparison with similar images simulated mathematically for
different X rays sources. The paper also shows the experimental radiography
of two biological samples taken from biopsies of mammas, where it is
possible to identify the presence of possible pathological lesions. The
results reached in this work point positively toward the effective
possibility of satisfactorily introducing those advanced detectors in
medical digital imaging applications.
