    Streszczenie angielskie: The aim of the study were the measurements and calculations of the phantom image quality, the average glandular dose and the overal number of examinations as a measure of evaluation of a mammography facility. The image quality estimation was based on the evaluation of the images of a phantom designed for accreditation purposes by the American College of Radiology (ACR). The following parameters were assessed: the number of visible phantom structures, the contrast between the acrylic ring in the phantom and its surrounding, the phantom background level and the number of visible artefacts. The mean phantom doses were measured with a Diados dosimeter (PTW). The measurements of individual patients doses were made using the same methods and definitions as those used for mean phantom dose determinations, but related to parameters of the examination of an individual patient. The overall number of examinations performed on a mammography unit was used for the evaluation of a mammography facility in Poland. The data induced the number of examinations in Poland in 1997, and those in Warsaw in 1997-1999. This study is based on protocols of the quality control (published in the Mammography Quality Manual (ACR) for 37 mammography units. The image quality in a large majority of cases exceeded the tolerance limit (only 4 of 37 met the necessary requirements). In all mammographs tested, the values of the mean phantom doses (3 mGy) were lower than this value. Individual dose distributions can be a measure of controlling the conditions under which mammography examinations are performed, pointing...

    Tytuł oryginału: Evaluation of physical parameters of a CT unit in radiotherapy treatment planning.

    Streszczenie angielskie: The aim of this study was to evaluate physical parametes of a Siemens Somaton DRH computed tomography unit used for radiotherapy treatment planing. Three groups of measurements were performed: control of the image geometry, dose absorbed by the patients, and estimation of the function relating CT numbers to tissue electron density. It was found that for properly performed examination, doses absorbed by patients do not exceed reference dose values published in the European Commision guideliness. Additional reference levels could be established for non-diagnostic examinations performed only before radiotherapy treatment planing (breast tomography). Function relating CT numbers to issue electron density determined for the Siemens Somatom DRH does not differ significantly from that used in the Cadplan treatment planing system in the soft tissue range. Beam hardening artefacts and changes in image slice width are the main causes of variations in CT numbers. Inaccuracies of dose distribution calculations due to the observed inaccuuracies were also estimated.
