Improvement of Image Quality and Radiation Dose Reduction in Digital Radiography Using an Integrated Wavelet- Transform-based Method
This study presents an improved wavelettransform-based method for offering a possibility to reduce the radiation dose while maintaining a clinically acceptable image quality. The proposed method integrates a straightforward extension of our previously proposed wavelet-coefficient weighted method and the existing BayesShrink thresholding method. Experimental results demonstrated that the propose...
متن کاملEffects of Kilovoltage on Image Quality and Entrance Surface Dose in Lumbar Spine Digital Radiography
Introduction: Digital radiography possesses a wide dynamic range and has a major advantage in producing an acceptable image of diagnostic value even though overexposure occurs. Lumbar spine (LS) radiography is the most common examinations that gives high radiation dose to patients and accounts for the highest collective population dose of any conventional radiographic ...
متن کاملA Phantom Study for the Optimization of Image Quality and Radiation Dose for Common Radiographic Examinations in Digital Radiography
Introduction: Phantom studies facilitate the implementation of radiation dose surveillance as a function of radiographic technical parameters for minimizing patient radiation dose. The evidence of such investigations can then be used to evaluate technical parameters used in the radiographic procedures to reduce radiation dose without compromising the image quality. Material and Methods: This ex...
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 کاملRadiation Effects on Digital Radiography
In the moment of any given imaging task and thus over the lifetime of a detector, the deposition of certain amount of radiation dose in an electronic pixel element is inevitable. This radiation effect can give rise to a change of the pixel-element characteristics such as the leakage current of a photodiode and the threshold voltage of thin-film transistors (TFTs) [1], and which may consequently...
