[en] Conventional mammographic imaging suffers from a low specificity. The main cause is the small difference in the x-ray attenuation properties of healthy and diseased tissue leading to poor contrast in the image. It has been observed that additional information on breast tissue type can be obtained from x-ray diffraction effects. A study of excised normal and neoplastic breast tissue samples using x-ray diffraction apparatus has been observed that significant differences exist in the measured spectra between carcinoma and healthy tissue adjacent to the carcinoma. Such a difference allows tissue type to be characterised according to is diseased state. Furthermore the information can be applied to improve diagnosis. It is proposed that collection and analysis of the scattered x-rays present during a mammographic procedure can supply the additional information and be used to improve the image contrast. The ultimate aim of the project is to improve the specificity of x-ray mammography. (authors)

[en] Quality Control (QC) performed on 99 intraoral dental X-Ray units, installed in equal in number dental offices, at the Achaia prefecture, a region of south west Greece. The QC procedure includes collection of general information, radiation safety checks, beam qualitative and quantitative characteristic checks, and film processing checks, according to international established protocols. The collected data are characterised by a non-uniformity and in some cases indicate a poor performance level. The results of the study on a representative sample of dental X-Ray units helps to map the existing situation and may be useful in the reviewing and optimisation of the applied process. (authors)
