Abstract：To find an objective evaluation method of digital radiography (DR) image quality, which is suitable for DR empirical
evaluation and has high feasibility and is convenient for field measurement. By introducing the image quality evaluation methods
of DR, two comprehensive and objective evaluation methods, DQE and IQF, were selected. Then, their basic ideas, principles,
algorithms and implementation methods were sorted out and shadows were discussed. The advantages and disadvantages and
applicability of these two methods were compared. IQF can be used as an objective evaluation method for lateral comparison of DR,
which provides a basis for on-site empirical evaluation of subsequent DR.
