Title Review of a simple noise simulation technique in digital radiography

چکیده
Reduction of exposure dose and improvement in image quality can be expected to result from advances in the performance of imaging detectors. A number of researchers reported on methods for simulating reduced dose images. The simplest method provides reduced dose images by adding white Gaussian noise with certain standard deviation to the original image. The aim of this paper was to develop and validate a fundamental system with a graphical user interface for simulating reduced-dose images by the simple method. Here, we describe a technical approach in a flat-panel detector (FPD) system and validate the simulation performance objectively and subjectively. Additionally, the technical limitations and possible solutions are suggested based on the
