Factors affecting image quality

Published

Journal Article

When compared to the radiograph generated by Roentgen in 1895 the brighter side of image quality today is that we have images which give much better contrast between tissues with minor variation of density or other characteristics; better differentiation through a variety of imaging modalities aimed at in vivo histology, in vivo physiology and in vivo biochemistry; better means to study and quantify motion, function and so on. The other side of the coin is that conventional radiography of 1895 is still the main-stay of radiology and the image clarity of direct radiography as practiced a century ago is still a model for screen film radiography of today. However, the capability to achieve a good image with a radiation dose lower than 1/50(th) as compared to direct radiography, is a great achievement. Factors which determine the image clarity and the way the image quality can be improved are presented.
