How to turn video materials into clear photos at home

  When providing consultation, we found a problem that the MRI or CT or DSA results provided by the patient were not clear. The diagnosis of brain surgery is highly dependent on images, and subtle differences in images can lead to completely different results in diagnosis and treatment. Provide a simple and effective way to take clear pictures at home.  1, find a sunny day, glass windows, facing the sun; 2, CT or MRI film to distinguish the upper and lower, left and right (there are letters on the film, see clearly on the good), the film on the glass, the four corners with transparent tape fixed, be sure to lay the film flat, can not shake; 3, the film around the light transmission with newspaper or something else to block a file; pull the curtains, so that the best indoor light can be darker. So that the contrast between indoor and outdoor light is relatively large; so the effect will be much better; 4, the camera (ordinary card machine or cell phone is perfectly fine) is best set to macro mode, be sure to prohibit the flash flash; pixel is not required to be very high, medium on it.  5, CT or MRi a large film is divided into many small images, when taking pictures, must be shot one by one small image. Of course, take more photos, otherwise a large film into a photo of the doctor is unable to see clearly. If you can know those images are lesions, upload the best, not all images are useful.  6, the rest is to take pictures when the hand to stabilize, anti-shaking, which is the basic problem of taking pictures.  The above few do, almost enough.
