What is radiographic parallax?

Radiographic parallax is a phenomenon that occurs in radiography when an object is imaged from different angles, leading to a discrepancy in its apparent position on the radiograph. This effect arises due to the three-dimensional nature of the object and the two-dimensional representation in the image. As a result, overlapping structures may appear to shift relative to one another, which can impact the interpretation of the radiographic image. Understanding radiographic parallax is important for accurate diagnosis and assessment in medical imaging.
