Question

Suppose you want to take a chest x-ray with an x-ray source that has a divergence of 1 degrees. If the film is 1 meters from the (point) source, how big is the film in centimeter s?

Step 1

The description is as shown in the diagram.

Step 2

Here, *d* is the source-screen distance, *ϴ *is the divergence angle and *D* is...
