According to reports, San Francisco, the United States, declared a blockade. In addition to measures such as closing the city, it is also important to seek medical treatment in a timely manner. X-ray machines and bucky stands are effective instruments to assist in the rapid diagnosis of viruses. In addition, our company’s exposure hand switch, photography flat bed, x ray collimator, x ray grid, etc. are also good auxiliary equipment. We hope that the pneumonia virus will pass quickly, and that the people of the world will be healthy.
