A Comparison of Patients Absorption Doses with Bone Deformity Due to the EOS Imaging and Digital Radiology
Background: This study has aimed to measure the patient dose in entire spine radiography by EOS system in comparison with the digital radiography. Methods: EOS stereo-radiography was used for frontal and lateral view spine imaging in 41 patients in a prospective analytical study. A calibrated dose area product (DAP) meter was used for calibration of the DAP in EOS system. The accuracy and pr...
متن کاملThe Practice of Chest Radiography Using Different Digital Imaging Systems: Dose and Image Quality
Introduction: The study was undertaken to evaluate the practice of chest radiography using different digital imaging systems and its influence on dose and image quality. Materials and Methods: The study was carried out in two hospitals from March 2016 to June 2016. Sixty ambulatory patients aged 21 to 60 years who were able to cooperate without difficulty and weighed between 60 to 80 kg were ...
متن کاملComputational Photography: Coded Exposure and Coded Aperture Imaging
The emerging field of computational photography is exploring the possibilities of digital photography beyond the imitation of film cameras. Novel illumination, optics, sensors, and processing methods are employed to expand the set of images that cameras can create. This thesis introduces the field of computational photography and presents two exemplary techniques that address the problem of blu...
متن کاملRock mass structural characterization via short-range digital photogrammetry
Because of the important role of rock mass structural properties on its mechanical behavior, determining the qualitative and quantitative properties of has been a subject of intense research. In this regard, numerous techniques such as scanline surveying, cell mapping, and geologic structure mapping have been proposed. However, applying such field surveying techniques for rock mass properties i...
متن کاملAn Evaluation of Digital Imaging Studies in an Outpatient Orthopedic Setting
Background: Distribution of radiographic images in the outpatient setting on compact discs-recordable (CD-R) iscommonplace. Opening, manipulating and interpreting these can be challenging. This study evaluated the availabilityand ease of use of CD-R to evaluate digital images in an outpatient orthopedic setting.Methods: 118 CD-R containing diagnostic studies were evaluated by ...
متن کاملAgreement of Bitewing and Digital Panoramic Radiographies in the Detection of Proximal Caries
Background & Aims: Conventional radiography is used for the diagnosis of problems such as dental caries and failure in root canal therapy. The diagnosis accuracy of conventional radiography is acceptable in the evaluation of anatomical and pathological structures. However, it seems that by using digital radiography we can obtain more information in this field. The aim of this study is to compar...
