ABSTRACT:
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 sensitized 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 by the method disclosed herein;
said method of image formation being characterized by the steps of
