Question

Quizplus · Accepted Answer

For an internally rotated AP shoulder projection and a lateral humeral projection, positioning the imaginary line connecting the humeral epicondyles perpendicular to the image receptor (IR) is correct. This ensures proper orientation and visualization of the anatomical structures.
