What can I know by taking an X-ray?

X-ray can evaluate the lung condition, the approximate size and shape of the heart, whether the pulmonary artery is widened, pleural effusion, fractures and so on.

X-ray chest film can be used to examine and diagnose lung diseases, the size of the heart, ribs, pleura, chest wall mediastinum, bronchus and so on.

X-ray can be used to check the perforation of digestive system, such as gastric perforation, intestinal perforation, intestinal obstruction and other acute abdomen, and can also be used for salpingography and pyeloureterography.

The application of X-ray in medical diagnosis is mainly based on its penetrability, differential absorption, photosensitivity and fluorescence.

X-ray diagnosis technology has become the earliest non-invasive visceral examination technology in the world.

Production:

The strong radiation of 1. electrons. The metal is bombarded by high-energy electrons, and the electrons decelerate sharply in the process of hitting the metal. According to electromagnetism, charged particles with acceleration will radiate electromagnetic waves. If the electron energy is large, such as tens of thousands of electron volts, X-rays can be generated. This is the method of generating X-rays used in laboratories, factories, hospitals and other places.

2. Electron transition inside atoms can also produce X-rays. According to the theory of quantum mechanics, electrons will emit photons when they jump from high energy level to low energy level. If the energy difference between energy levels is relatively large, photons in the X-ray band can be emitted.
