Which statement correctly describes the typical shape of anatomical structures in radiography?

Explanation:
In radiography, a 2D image is a shadow of a 3D object, so the outline you see is the projection of the structure’s actual cross-section onto the detector. Many anatomical structures have smooth, convex surfaces, and when they are projected, their silhouettes commonly appear rounded. That makes round or oval outlines the typical appearance in radiographs. Shapes like square or triangular aren’t characteristic of normal anatomy, and while outlines can be irregular or overlapped in some cases, the common, expected appearance is a round or oval shape.
