“…[7][8][9][10][11] However, in some cases, not all parameters that characterize the x-ray spectra are available in these models. 4 Indirect methods to obtain a representation of x-ray spectra can also be found in the literature, for example, the reconstruction of measured scattered x-ray spectra 12,13 and nonclinical spectra. 14 However, the measurement of x-ray spectra can provide an accurate representation of a mammography radiation beam, and it is the best procedure to improve image quality and dose optimization in mammography.…”
