Which characteristic must NOT be included in a quality radiograph?

A quality radiograph is determined by several key characteristics that contribute to its diagnostic value. Among these, properly positioned anatomy and physiology, which is the characteristic mentioned in the response provided, is indeed crucial for obtaining high-quality images. Accurate positioning ensures that the anatomical structures of interest are clearly represented without distortion or overlap, allowing for precise analysis and diagnosis.

The characteristic of adequate exposure factors is essential, as it ensures that the radiograph has the right level of penetration, providing the necessary detail without excessive darkness or brightness. Sufficient radiographic density and contrast allow for clear differentiation between various tissues and anatomical structures, which is vital for effective diagnosis. Appropriate sizes of the field are also important, as they help to limit unnecessary exposure to surrounding tissues while including the area of interest.

Proper positioning plays a significant role alongside these other factors in the overall quality of a radiograph. Therefore, while all characteristics are important in their own right, proper positioning is indeed one that must not be overlooked in producing a high-quality radiograph.
