What is the disaster recovery check for?
The imaging principle of DR and CT is the same, both are X-ray imaging, because X-rays have a strong penetrating power to human tissues and structures. However, the density of human tissue structure is different, and the amount absorbed when X-rays penetrate is also different.
Extended data
The main advantages are:
1, the image is clear and the digital image resolution is high. By adjusting the window width and window position, the lung tumor lesions behind the mediastinum can be clearly seen in DR photos, and the ribs overlapping with the diaphragm can also be clearly displayed, thus reducing missed diagnosis and misdiagnosis, and at the same time helping to find smaller lesions early and providing opportunities for early diagnosis and treatment of lesions.
2. The radiation dose received by the examinee is obviously reduced, thus reducing the adverse effects of X-rays on human body, especially for children and adults of childbearing age who are sensitive to X-rays. DR radiography is a good choice when X-rays are needed.
3, rapid imaging, exposure for a few seconds to get a digital image. First, the image can be immediately observed on the fluorescent screen. After the image quality is qualified, the image can be uploaded to the post-processing workstation for reading and sending the diagnosis report. If the image quality is not good, you can take photos again, which greatly improves the work efficiency and reduces the waiting time of patients.
