Without contrast, objects within the body will not be visible, and differentiation between organs and adjacent tissues would be difficult The key factors that influence the sharpness of an image relate to the size of the source of x-rays (focal spot), the physical characteristics of the x-ray detector system (area and thickness), and the presence of any motion blur because of the finite duration of all radiographic exposures Assessing the quality of diagnostic images is subjective and influenced by factors such education, skills, and experience of the assessor.
