Physical measures (Objective)

The term, objective measurements refer to the description of the physical characteristics within the digital radiographic system. They have the ability to describe the performance of the whole imaging system by referring to the image quality. These physical measures include a signal to noise ratio (SNR), contrast to noise ratio …

Image quality evaluation

Both the utility of radiographic images and the precision of image interpretation are highly dependent upon image quality and observer competency. There are several approaches that can be used to measure the quality of an image (Alsleem & Davidson, 2012), and a review of the literature revealed even more methods …
