In a left anterior oblique (LAO) view, where is the spine located relative to the heart?

Explanation:
In oblique views, rotating the patient changes how structures overlap on the film. In a left anterior oblique view, the left side of the chest is closer to the detector, and the heart is angled so that its right side sits more toward the front. The spine lies behind the heart, and because of this rotation, it projects to the right side of the cardiac silhouette on the radiograph. So, the spine appears on the right of the heart in LAO. (In a right anterior oblique view, the spine would appear on the left.)
