Abstract

L'INVENTION CONCERNE UN PROCEDE ET UN APPAREIL DE RADIOGRAPHIE ELECTROSTATIQUE. ELLE SE RAPPORTE A UN PROCEDE SELON LEQUEL LA SENSIBILITE EFFICACE D'UN PHOTOCONDUCTEUR EST ACCRUE, PAR UTILISATION D'UNE CHARGE D'UN PHOTOCONDUCTEUR, PUIS D'UNE EXPOSITION QUI NE FORME QU'UNE IMAGE ELECTROSTATIQUE LATENTE PEU CONTRASTEE, CETTE IMAGE RECEVANT ALORS UN CACHE D'UN AGENT DE VIRAGE QUI, APRES IRRADIATION DE LA TOTALITE DU PHOTOCONDUCTEUR, PERMET L'ACCENTUATION DU CONTRASTE DE L'IMAGE ELECTROSTATIQUE QUI EST ENSUITE DEVELOPPEE ET EVENTUELLEMENT REPORTEE SUR UNE FEUILLE DE SUPPORT. APPLICATION AUX RADIOGRAPHIES ELECTROSTATIQUES POUR OPERATIONS MEDICALES.
