1. Analysis of the reproducibility of the gray values and noise of a direct digital radiography system
The aim of this study was to evaluate the reproducibility of the gray values and noise of a direct digital radiography system (Visualix eHD) for various exposure times and analyzed regions. To obtain radiographic images in a standardized manner, the digital sensor of the system and a stepwedge were positioned in a phantom at a focus-film distance of 30 cm in

3. Avaliação da acurácia dos métodos radiográficos convencional e digital direto na análise da extensão de lesões de cárie oclusais em molares decíduos. estudo in vitro / Accuracy evaluation of conventional and direct digital radiographic methods in the analysis of occlusal carious lesions extension in primary molars. An In Vitro Study
This in vitro research, evaluated the accuracy of the direct digital radiographic method compared to the conventional radiographic method in the analysis of the extension of occlusal carious lesions in primary molars. The material was composed by 55 primary molars presenting pigmentation and, at least, one suspect site of occlusal carious lesion, these teeth

4. Filmes finos de iodeto de chumbo como detector de raios-X para imagens médicas / Lead Iodide Thin Films as X-ray detectors for Medical Imaging
In the last few years, great interest has been focused to high atomic number and wide band gap semiconductor materials for applications in room temperature ionizing radiation detection using the direct detection method. Some materials such as PbI2, HgI2, TlBr, CdTe and CdZnTe are good photoconductors and can be used at room temperature. As a good candidate,

5. Assessment of calibration tools of three digital radiography systems / "Validação das ferramentas de calibragem de medidas em três sistemas de radiografia digital"
Technological development aims at reducing exposure of both the professional and the patient to ionizing radiation, improving patient treatment and aiding final diagnosis. The combination of computer technology and radiology, i.e. digital radiography, has made this possible. One of the tools of digital radiography systems is calibration prior to measurement.

6. Avaliação da imagem digital em radiografias da articulação temporomandibular
The purpose of the present study is to evaluate comparatively the image got by three radiographic methods: conventional transcranial radiography, digitized image of the conventional radiography and direct digital image. For that, 22 hemiheads cadaver were used, fixed in formaldehyde which were radiographed in standard way with the help of specific head holde
