[Contrast enhancement of x-ray images on layers exposed to a superimposed electric field]. / Uvelichenie kontrastnosti rentgenograficheskikh izobrazhenii na sloiakh, éksponirovannykh s nalozheniem élektricheskogo polia.

A method of raising the sensitivity of x-ray photomaterials using a pulsed electric field is considered. Methods for raising contrast of photo images by changing stages of x-ray film postexposure processing have been proposed. Processing in the proposed enhancing compounds makes it possible not only to raise sensitivity by one order or more but also to preserve a contrast coefficient value. Raising the contrast of photomaterials is important in medical radiography irrespective of electric fields imposing methods, therefore, it can be used in some radiodiagnostic procedures.
