The measurement of the linear attenuation coefficients of breast tissues is of fundamental
importance in the field of breast x-ray diagnostic imaging. Different groups have evaluated
the linear attenuation coefficients of breast tissues by carrying out direct attenuation
measurements in which the specimens were thin and selected as homogeneous as
possible. Here, we use monochromatic and high-intensity synchrotron radiation computed
tomography (SR CT) to evaluate the linear attenuation coefficients of surgical breast tissues …

Purpose The purpose of this work is the measurement of the linear attenuation coefficients of
surgical breast tissues using monochromatic computed tomography (CT) in the energy
range from 20 to 38 keV. This research is in the framework of the development of a facility of
phase-contrast breast CT with synchrotron radiation (SR). Methods CT images of three
formalin-fixed surgical breast samples, prepared from specimens of mastectomy, are
acquired at a SR facility. In order to measure the value of the linear attenuation coefficients …
