The Given

In order to set up a successful mammography screening program in the Republic of Srpska, a Siemens Mammomat 1000 X-ray machine was selected for analysis as the said mammography system is widely used in clinical practice. The variations in tube parameters (specific air kerma, high-voltage accuracy and reproducibility, linearity between exposure and dose exposure time) were monitored over a five-year period, from 2008 to 2012. In addition, due to observed daily fluctuations for chosen parameters, a series of measurements were performed three times a day within a single-month period (mainly October 2012). The goal of such an experimental set up is to assess short-term and long-term stability of tube parameters in the given mammography unit and to make a comparison between them. The present paper shows how an early detection of significant parameter fluctuations can help eliminate irregularities and optimize the performance of mammography systems.

ABSTRACTThe possibility of creating an 2D X-ray sensor array on the base of a-SiN:H thin films without switching elements and an X-ray conversion layer is presented in this report. The behavior of a-SiN:H Thin-Film Diode under X-ray irradiation, its limitations, and ways of increasing long-term stability and sensitivity of the sensor are discussed.
