LEYVA, A. et al. Empleo de detector semiconductor de c-Si del tipo microbandas en la obtención de imágenes radiográficas digitales de maniquíes y muestras biológicas de mamas. Rev. mex. fis. [online]. 2009, vol.55, n.4, pp.327-331. ISSN 0035-001X.

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 médical 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 médical digital imaging applications.
