X-ray is a type of electromagnetic radiation that has high-energy particles that can penetrate matter and is widely used in medicine, industry, and scientific research. A portable X-ray machine is a device used to check for abnormalities inside an object. This article will explain how a portable X-ray machine works.
1. The basic principle of X-ray.
X-rays are accelerated by a beam of high-energy electrons through a specific magnetic field, bombarding the cathode target and producing a stream of high-energy particles that penetrate the irradiated object and produce an X-ray image. The main reason for its occurrence is Compton scattering, that is, high-energy photons collide with the nucleus of matter, and part of the energy is absorbed, and the remaining part of the energy changes direction and propagates forward. This process is widely used in many scientific research and industrial applications.
Second, the structure and working principle of portable X-ray machine.
Portable X-ray machines mainly consist of a power supply, a main unit, and a monitor. Its working principle is to use X-rays to have different degrees of penetration ability to different substances, by irradiating the object and receiving its reflected or transmitted X-rays, and then through image processing to generate images. Specifically, when X-rays hit an object, the substance absorbs a portion of the energy, and the remaining energy is at different angles**, forming a scattering field. The detector measures the change in the scattering field, converts it into an electrical signal, and then undergoes signal processing and image reconstruction algorithms to form a visible image.
3. Application of portable X-ray machine.
Portable X-ray machines are widely used in industrial production, safety inspection, medical diagnosis and other fields. In industrial production, it can be used to check whether there are defects inside the product, such as cracks, bubbles, foreign bodies, etc.; In the security check, it can be used to check the passenger's luggage for prohibited items; In medical diagnosis, it can be used to examine the condition inside the patient's body. In addition, with the continuous development of science and technology, the volume and performance of portable X-ray machines are also constantly optimized, and may be applied to more fields in the future.
4. Safety precautions.
When using a portable X-ray machine, it is necessary to comply with the relevant safety regulations and operating specifications. Due to the penetrating ability of X-rays, prolonged exposure to X-rays can cause radiation damage to the human body, so necessary precautions need to be taken. In addition, for some special substances (such as items containing metals), special attention needs to be paid to the irradiation angle and time so as not to distort the image or interfere with the detection results.
In conclusion, portable X-ray machine is an important detection equipment that is widely used in various fields. Understanding how it works and its characteristics will help you better play its role. In the process of use, it is necessary to pay attention to safety issues and take necessary protective measures to ensure the safety of equipment and personnel.
