This article focuses on the types of equipment that are categorized as Class III radiographic devices. These types of devices have important applications in the medical and security screening fields. Firstly, x-ray devices used for human security screening are designed to ensure passenger safety and they are widely used in places like airports and stations. Second, medical x-ray computed tomography (CT) devices, which are used in medical imaging as a highly accurate diagnostic tool, can provide detailed information about internal structures.
Radiation therapy simulation positioning devices, on the other hand, are key devices in cancer treatment that help doctors pinpoint the location of tumors for precise radiation therapy. In the field of dentistry, dental x-ray devices are used to examine teeth and periodontal tissues to ensure oral health. Finally, X-ray baggage inspection devices are an important part of airport security screening, used to detect dangerous items that may be hidden inside packages to ensure public **** safety.
To summarize, the three types of radiographic devices include equipment critical to human safety screening, medical diagnostic tools, and radiation detection equipment to ensure safety and health, and they play an integral role in their respective fields.
