[Theoretical aspects of the formation of a roentgenokymographic image]. / Teoreticheskie aspekty formirovaniia rentgenokimograficheskogo izobrazheniia.

A procedure for estimating optimal values of parameters for the roentgenokymographic devices, including the basic parameter--the slit width, has been devised. An interrelation between the slit width in ordinary and perspective protective roentenokymographic devices was determined. The optimal slit width in the ordinary roentgenokymographic device was found to equal 0.5+0.03 mm, and in the protected roentgenokymographic device the investigation of adults and children indicated 0.15+0.02 and 0.22+0.02 mm, respectively. The resulting theoretical values are supported by experimental findings.

The consideration of the process attending the formation of a roentgenokymographic image enables one to theoretically substantiate the informative characteristics of the roentgenokymographic apparatus, as well as concrete numerical values of the principal parameter of the kymogrid i.e. the dimensions of the slit. In an ordinary roentgenokymograph the slit should equal 0.5 mm, while in a protected one--0.13 mm (in examination of adults) and 0.24 mm (in examination of children).
