Radiographic techniques in screen‐film mammography
The objectives of this study were to document imaging physics parameters associated with mammography physics surveys, and investigate how the choice of tube potential affects average glandular dose (AGD) and x-ray exposure time. Data from 60 mammography units were obtained pertaining to representative values of mAs, exposure time, half value layer, AGD and film density when acquiring phantom im...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

15 صفحه اولClinical evaluation of breast dose and the factors affecting breast dose in screen-film mammography.
PURPOSE To investigate the factors affecting the mammographic breast dose. MATERIALS AND METHODS The assessment was done on 622 qualified mammograms obtained with use of "variable kV" technique, i. e., semiautomatic mode, in screen-film mammography. Actual breast doses were calculated and analyzed to determine the roles of two screens and three films, two anode/filter selections (Mo/Mo and Mo...
متن کاملA Comparison of the effectiveness of Mammographic Film-Screen and Standard Film-Screen in the Detection of Small Bone Fractures
The use of mammography film-screen is limited in general radiography. The purpose of this study was to compare the effectiveness of mammographic film-screen and standard film-screen systems in the detection of small bone fractures. Radiographs were taken from patients' extremities and neck areas using mammography film-screen and standard film-screen (n=57 each). Fourteen other radiographs were ...
