A phantom study for optimization of image quality and radiation dose for common radiographic examinations in digital radiography

In minimizing patient radiation dose to a minimum, radiation dose surveillance as a function of radiographic technical parameters can be carried out via phantom studies. The evidences afforded can then be used to evaluate technical parameters used in the radiographic procedures to reduce radiation d...
