DR equipment, that is, digital X-ray equipment (Digital Radiography), is a medical equipment widely used in modern medical imaging. It can be used to diagnose diseases in different parts and provide clearer and more accurate imaging results. The main structure of the DR device consists of the following parts:
1. X-ray emission device: X-ray emission device is one of the key parts of DR equipment. It is composed of X-ray tube, high voltage generator and filter etc. The X-ray emitting device can generate high-energy X-rays, and can be adjusted and controlled according to needs. The high-voltage generator is responsible for providing the appropriate voltage and current to generate the required X-ray energy.
2. Flat panel detector: Another important part of DR equipment is the detector. A detector is a sensor device that converts X-rays passing through human tissue into electrical signals. A common detector is a Flat Panel Detector (FPD), which consists of an image sensitive element, a transparent conductive electrode and an encapsulation layer. FPD can convert X-ray energy into electrical charge, and transmit it to computer for processing and display through electrical signal.
3. Electronic control system: The electronic control system of DR equipment is responsible for managing and controlling the operation of X-ray emitting devices and detectors. It includes computer, control panel, digital signal processor and image processing software, etc. The computer is the core control center of DR equipment, which can receive, process and store the data transmitted by the detector, and convert it into visualized image results.
4. Display and image storage system: DR equipment presents image results to doctors and patients through high-quality displays. Displays typically use liquid crystal technology (LCD), capable of displaying high-resolution and detailed video images. In addition, image storage systems allow image results to be saved in digital format for subsequent retrieval, sharing and comparative analysis.
To sum up, the main structure of DR equipment includes X-ray emission device, flat panel detector, electronic control system, display and image storage system. These components work together to enable DR devices to produce high-quality and accurate medical images, providing more precise diagnosis and treatment plans. With the continuous development of technology, DR equipment is also continuously improved and optimized to provide more efficient and reliable tools for medical diagnosis.
