DR detection is a new technology of digital radiography under computer control.DR equipment is a new generation of x-ray detection equipment. During the DR examination, the subject must remove all foreign objects, including clothes, bras, necklaces, etc., i.e., all items that affect the examination are removed before the examination.
DR and CT share the same imaging principle of imaging through x-rays, which are highly penetrating to the body's tissue structure. However, different tissues have different densities and different amounts of absorption when x-rays penetrate.
Expanded Information:
Note:
1. The image is clear and the digital image resolution is high. By adjusting the window width and window position, the DR photo can clearly see the lesions of lung tumors after mediastinal cardiography, and can also clearly show the overlap of ribs and diaphragm. This can reduce the leakage and misdiagnosis, and also can detect the early small lesions, providing the opportunity for early diagnosis and treatment of the lesions.
2. It greatly reduces the radiation dose to the examinee and minimizes the adverse effects of x-rays on the human body, especially children and adults of childbearing age who are sensitive to x-rays. When x-ray examination is needed, DR film is a good choice.
3. Fast imaging, a few seconds after the digital image exposure can be obtained, one can immediately observe the image on the screen, the image quality is qualified can be immediately uploaded to the image post-processing workstations to read send a diagnostic report, if the quality of the image can also be photographed to greatly improve efficiency and reduce the patient's waiting time.
