A new roentgenological technique of a bronchial tree examination--bronchoholography has been described. To receive holographic image of a contrast bronchial tree the authors introduced changes and additions in usual bronchography technique: a contrast bronchial tree has been recorded on a video tape of a tape recorder at the moment of deep inspiration, the patient was rotating around its vertical axis at that time. Then bronchial tree videogram has been transferred on a cine film. After this 25--40 exposures which represented bronchi images in different foreshortenings--straight, angle and side chest projections have been selected. The selected exposures have been reproduced with the help of a laser light source by a holographic method on a photomaterial and thus a superpositional deep hologram of a bronchial tree has been received.
