What is the clinical significance of standing posture, sitting position, lying position and oblique position in X-ray photography?

Standing posture is generally dominated by abdomen, mainly acute abdomen, such as intestinal obstruction and perforation of cavity organs.

Abdominal supine position is commonly seen in patients with urinary calculi and suspected intestinal obstruction.

Sitting position is generally that the patient does not stand and do oblique position. Generally, lumbar vertebrae and chest are more common, mainly looking at fractures.

Others are basically conventional postures, some need to stand and take pictures, and some need to lie down to see the situation.
