Many patients have long descriptions of disease conditions or examination reports during consultations, but often the descriptions cannot be understood or even misunderstood by doctors because they are not medical people, instead a clear imaging photograph is often half the battle. Here is how to take CT films or MRI (magnetic resonance imaging) and other medical examination films at home. The key is 1, hand stability, 2, bright background 1, stability: ask young people at home to help, they generally hold the camera more stable; or you can place the camera on a table (equivalent to a tripod), use the camera self-timer function to shoot (shutter shooting moment, the camera is absolutely stable); then professional, you can match a tripod, use the shutter line or self-timer function is better. 2, the background is bright: in the hospital can be used with the doctor’s office reading lights, the best effect; no reading lights at home, you can put the film against the fluorescent light, but often the film will shake and uneven background light, the effect is not good; the best way is a sunny day, the film is fixed in the window glass (do not have direct sunlight, to ensure uniform light transmission can be), the film is fixed with transparent tape, and then shoot, the effect No less than reading the film light. 3, other skills (can not read, do not learn): the camera should focus on the film right in the middle, an image will be completely framed in the lens; sensitivity (ISO) selected at 100, so that the image is more delicate; can use automatic gear shooting; but can not use the flash; in the case of ensuring successful focus, the camera and film distance as close as possible; can use close mode or macro mode (generally Digital cameras are available). For vascular surgery, uploading “reconstruction films” (those “stereoscopic” images where the patient can more or less see the vascular structure) is preferred. For most of the other cross-sections, the patient can choose the ones that have “arrows, distance measurements, and indication text” somewhere on the image (these are often the typical images selected by the imaging physician). If you zoom in and look at the image after taking it, and see that the text around the image is clear and free of ghosting, then you have met the standard, and at the very least, such films are sufficient for online consultation. The following are some of the films I took, you can refer to this degree of shooting can be. I was shot with a cell phone, so you use a digital camera, definitely should not be worse than these shots!
