What is a consequence of a shorter target-to-panel distance?

A shorter target-to-panel distance generally leads to greater distortion of the image. This distortion arises because the geometry of X-ray projection becomes altered, which can result in variations in the size and shape of the structures being imaged. When the target (where the X-rays are generated) is closer to the image receptor (the panel), the angles at which X-rays strike the receptor can diverge more significantly, causing objects to appear differently than they actually are.

This concept is particularly critical in radiography and fluoroscopy, where accurate representation of anatomical structures is essential for diagnosis. The increased distortion can obscure important details and mislead interpretations of the images. Understanding the relationship between target-to-panel distance and image distortion is vital for ensuring accurate imaging outcomes in clinical practice.

The other choices, while addressing different aspects of imaging, do not accurately reflect the consequences of shortening the target-to-panel distance. For instance, reducing skin dose and improving image clarity would generally be related to increasing the distance, while the nature of the tubes (table tubes versus under-the-table tubes) doesn’t inherently alter the implications of image projection geometry.
