Many patients upload images that are not clear enough. Here are some tips for turning over X-rays, CT and MR films. 1. Find a good background transmission light source The light source should meet the conditions of uniform, bright and white. The most ideal is a fluorescent light box covered with white plastic panels used in hospitals. If you do not have the following two methods: (1) computer screen method: open the program – Microsoft Office – Microsoft Office PowerPoint, do not enter any words without any template, click the lower left corner of the like a screen “start projection button”, the screen will be all white. The brightness to the brightest will become a uniform background light source. (2) clear sky method: clear weather, with a cloudless bright sky as the background. Film is best to have something to rely on for stability. 2, set up a good camera photo style should be set to monochrome, grayscale or black and white mode, photo pixel 1M or so is enough (the current general digital camera or cell phone pixels are more than 5 million, choose a low-range size photos can be). Photos are too large to upload online; unless they are compressed and sent directly to the doctor’s email address in bulk. Camera flash must be forced off, and the photographer should not wear light-colored tops (if worn, black cloth should be used to cover the light), and other indoor light sources should also be turned off to prevent reflections. The camera is best to use a tripod and other things fixed, if handheld to steady, exposure speed should be fast enough (depending on the intensity of light to choose 1/60 seconds or 1/125 seconds). Focal length should be manually right, to see the small letters on the film is appropriate. 3, choose a good range of general X-ray film, CR film, DR film only a single or 2-4 small picture can be shot as a whole. When there are many small pictures in CT, MR, etc., you can take 4 small pictures at a time, or ask the doctor to find the most critical small pictures to shoot.
