DETERMINATION OF THE SPATIAL-RESOLUTION OF X-RAY-FILMS

A method of spatial resolution determination of X-ray films is describ ed. The technique is based on the use of a mask with a pattern of rand omly distributed transmitting and nontransmitting areas. Images on X-r ay materials were obtained with the use of synchrotron radiation from the S-60 (FIAN) synchrotron. It is suggested that X-ray images can be processed by the linear filter technique, The results of test measurem ents using RAR2490 and Kodak 10106 X-ray films are presented and compa red with data obtained by other methods.
