title: [Operation of the optical centering guides of x-ray diagnostic apparatus].
abstract: Because of a long-term operation of roentgenodiagnostic apparatus the light field illumination intensity of optical centering devices falls. An analysis of possible causes accounting for this phenomenon justified recommending to rate the intensity of the centering device field illumination and also to search for new materials for manufacturing a base for the centering devices mirrors.
