Understanding and Managing Noise Sources in X-ray …

https://www.carestream.com/blog/2020/04/21/understanding-and-managing-noise-sources-in-x-ray-imaging/

The design of a detector determines how close the final displayed image comes to that fundamental threshold on image quality that I described earlier – and that, once again, is limited by the laws of nature. It is interesting to note that the fundamental theories and understanding of the physical processes involved in … See more

A method for modeling noise in medical images - IEEE Xplore

https://ieeexplore.ieee.org/document/1339429

We have developed a method to study the statistical properties of the noise found in various medical images. The method is specifically designed for types of noise with uncorrelated fluctuations. Such signal fluctuations generally originate in the physical processes of imaging rather than in the tissue textures. Various types of noise (e.g., …
