Abstract:
1. An image-forming combined system for medical diagnosis application comprising a combination of a photothermographic material and an X-ray intensifying screen, wherein the photothermographic material comprises: a support and, disposed on both sides of the support, image-forming layers, each of which comprises a non-photosensitive organic silver salt comprising silver behenate, a photosensitive silver halide comprising tabular grains, a binder, a bisphenol reduction agent, a color toning agent, an organic polyhalogen compound, and a silver iodide complex forming agent that, after thermal development, substantially reduces visible light absorption caused by the photosensitive silver halide; the photosensitive silver halide tabular grains have an average sphere-equivalent diameter in a range from 0.3 μm to 5.0 μm and have a silver iodide content of 90 mol % to 100 mol %; the silver iodide complex forming agent is contained in a range from 50 to 300 mol % relative to an amount of the photosensitive silver halide; the silver iodide complex forming agent reduces a transition absorption of silver iodide of the photothermographic material after thermal development, which resides in the vicinity of 423 nm, to ½ or less than that before the thermal development; and the photothermographic material is capable of being recorded imagewise by using the X-ray intensifying screen.
