Abstract

Una struttura radiografica comprendente: un elemento radiografico che comprende un supporto e strati anteriore e posteriore di emulsione agli alogenuri di argento stesi sulle facce opposte del supporto, e una coppia anteriore e posteriore di schermi di rinforzo rispettivamente adiacenti a detti strati anteriore e posteriore di emulsione, in cui almeno uno di detti strati di emulsione agli alogenuri di argento mostra un indice di rigonfiamento inferiore al 140% e un tempo di scioglimento tra 45 e 120 minuti, e la differenza di contrasto tra della coppia di strati di emulsione agli alogenuri di argento è almeno 0,5, in cui la differenza di emissione di luce, stimolata dal raggi X tra detta coppia di schermi di rinforzo è almeno 0,6, e in cui il cross-over medio a guisa di immagine di detto elemento radiografico è inferiore al 5% a densità ottiche tra 0,5 e 1,75 e nell'intervallo tra il 5% e il 15% a densità ottiche tra 1,75 e 3,25, detto cross-over a guisa di immagine essendo misurato secondo la formula descritta nella descrizione.
