“…The PSNR criterion also proposes that the image quality from a mathematical point of view will be better when using a wavelet compression algorithm because it keeps the image distortion low when the compression ratio is increased sharply (19,25). In general, a processed image is acceptable to the human eyes if its PSNR is greater than 30 dB (26).…”

2012) Evaluation of the radiation dose to a phantom for various X-ray exposure factors performed using the dose area product in digital radiography, Radiation Effects and Defects in Solids: Incorporating Plasma Science and Plasma Technology, 167:12, 954-970,The aim of this study is to measure the dose area product (DAP) in digital radiography by using a DAP meter to determine the X-ray exposure. Pediatric X-ray examinations can be obtained for any radiographic examinations using the selected radiographic examination parameters (kVp and mAs), the DAP information recorded. The best peak signal-to-noise ratio (PSNR) at a fixed tube voltage of 70 kVp was obtained at tube currents of 20 and 32 mA, whereas the best PSNR at a fixed tube current of 25 mA was obtained at a tube voltage of 73 kVp. The fixed tube voltage of 70 kVp and the fixed tube current of 25 mA could help to obtain the best image quality and depict the spatial resolution of an anthropomorphic torso phantom radiographic examination. The normalized data over the DAP were provided to determine the patient dose from radiography.
