Abstract (en)

A method of reproducing an electronically stored medical image on a hardcopy material is disclosed, said material comprising a support and on only one side thereof a silver halide emulsion layer and a hydrophilic colloid layer, wherein said emulsion layer comprises red sensitised homogeneous cubic silver chloride, silver chloroiodide, silver chlorobromide or silver chlorobromoiodide crystals having not less than 70 mole % of chloride ions and preferably not less than 90 mole %; not more than 1 mole % of iodide ions and an average crystal size of from 0.12 to 0.30 mu m and more preferred from 0.15 to 0.25 mu m; wherein said crystals are coated in an amount, expressed as an equivalent amount of silver nitrate of from 2 to 6 g per sq.m., and wherein said material has a hardening degree corresponding with a water absorption of up to 3 g per gram of gelatin at an emulsion side, the said water absorption being measured as defined herein; said method being characterised by the steps of image-wise exposure of said material with an electronically adressed red or infrared laser followed by development processing in a developer free from hardening agents in less than 20 seconds in a total processing time from 30 to 50 seconds from dry to dry, wherein said developer contains a compound corresponding to formula (I) given herein, a precursor thereof, a derivative thereof and/or a metal salt thereof, being more preferably (iso)ascorbic acid; replenishing said developer in an amount of not more than 100 ml per square meter of developed material; fixing said developer in a time from 2 to 10 seconds; rinsing and drying.
