What is the use of perspective? What diseases can be revealed?

Hello! Chest fluoroscopy is a common X-ray examination method. It uses the characteristics of X-ray's penetrability, fluorescence and photographic effect to make the human body form an image on the screen. Due to the difference in density and thickness of human tissues, when X-rays penetrate different tissues, the absorption degree of X-rays is different, so the amount of X-rays reaching the screen is also different, forming a black-and-white contrast image, which provides a basis for doctors' diagnosis. Now X-ray fluoroscopy, as a routine physical examination, is mainly used to check and diagnose lung diseases (including tuberculosis, lung tumors, etc. ), the size of the heart, ribs, pleura, chest wall mediastinum and bronchus.

I hope my answer is helpful to you!
