If an animal is having a D.V. radiograph taken, the beam will be traveling ____.

Back to front.
Front to back.
Left to right.
Right to left.

The correct answer is: Back to front.

In the context of a Dorsal-Ventral (D.V.) radiograph, the X-ray beam is directed from the front (the ventral side) of the animal to the back (the dorsal side). Therefore, the correct understanding is that the beam travels from front to back. This allows the resulting image to capture a clear view of the anatomy from the ventral aspect, which is essential for accurate diagnosis. Understanding the directional terms is crucial in radiography. "Dorsal" refers to the back or upper part of the animal, while "ventral" refers to the front or lower part. When obtaining a D.V. radiograph, the ventral surface is positioned closest to the imaging plate, and the beam enters through this surface, projecting towards the dorsal side. This directional approach is standard practice in veterinary radiology for assessing various conditions involving the thorax and abdomen.
