CAMRT Radiography Practice Exam

In an axio-lateral mandible view, which side is best demonstrated?

1. The side closest to the IR

2. The side furthest from the IR

3. The side perpendicular to the IR

4. Both sides equally

The correct answer is: The side closest to the IR

In an axio-lateral mandible view, the side that is closest to the image receptor (IR) is the one that is best demonstrated. This positioning technique is designed to minimize distortion and maximize the clarity of the structures being imaged. When the side of interest is placed closest to the IR, it allows for better detail and sharper images of that specific side of the mandible. The reason why the other options are less favorable relates to how the anatomy is projected onto the detector. The side furthest from the IR would appear more magnified and potentially less defined due to increased distance from the receptor. The side perpendicular to the IR does not provide optimal visualization since it does not take advantage of the specific angling and positioning necessary for an axio-lateral view. Finally, both sides being equally demonstrated would not be effective in this instance as the intent is to provide a clear view of the side closer to the IR, not to compare both sides equally.
