Why is proper tube alignment critical for image quality?

Explanation:
Proper tube alignment ensures the X-ray beam, focal spot, and image receptor line up so the geometry of the image is accurate. When alignment is good, the beam is centered on the receptor and perpendicular to it, keeping magnification uniform across the field and minimizing distortion. If the tube is misaligned, the focal spot projects off-center on the image receptor, and the distances from source to object and object to receptor become uneven. This causes geometric distortion and magnification errors across the image, degrading image quality.
