METHOD OF PULSE RADIOGRAPHY Russian patent published in 2002 - IPC

FIELD: pulse X-ray equipment, recording of fast-going processes. SUBSTANCE: method consists in exposure of set of cassettes with X-ray films to sequence of pulses of X-ray radiation., in supply by turns of working pulse of electric voltage to one cassette in step with next pulse of X- ray radiation. Simultaneously with supply of working pulse of electric voltage fed to one cassette additional pulse of electric voltage with amplitude less than amplitude of working pulse is fed to all cassettes not subjected to action of working pulse before. Additional pulse ensures diminished sensitivity for each film in corresponding cassette when compared with its sensitivity without supply of voltage to this cassette. EFFECT: reduced effect of previous X-ray pulses on formation of image by due X-ray pulses. 3 dwg
