Chest film DR (Digital Radiography), or digital X-ray chest film, is a digital imaging technology. While traditional X-ray chest film requires film for imaging, DR converts the signals from the imaged area into digital signals, which are then processed and stored by a computer to finally form a digital image. Compared with the traditional film chest film, DR chest film can be imaged more quickly and accurately, effectively reducing the patient's radiation dose and imaging time.
DR technology has a number of advantages, including: first, shorter imaging time, which means patients need to be exposed to X-rays for a shorter period of time during the examination, and lower radiation dose; and second, better imaging effect, digital technology makes it easier for doctors to more easily and more accurately observe the morphology and structure of the chest tissues and organs, so as to more accurately make a diagnosis; In addition, digital technology makes the storage and management of chest radiographs easier and more convenient, and also facilitates the management of patients' medical records.
DR technology can be applied not only in the field of chest imaging, but also in other medical fields, such as orthopedics and dentistry. For chest DR technology, it is generally used to detect diseases such as inflammation, tumors, infections and injuries in the lungs and chest organs. Specifically, DR chest films are often used to find lesions such as emphysema, pneumonia, and fibrosis in the chest, as well as to assess the size of the heart shadow and changes in the hilar structures.
