ABSTRACT:
The invention provides a photothermographic material having, on both sides of a support, an image forming layer including at least a photosensitive silver halide, a non-photosensitive organic silver salt, a reducing agent, and a binder, which is to be exposed with X-rays using a fluorescent intensifying screen, wherein (1) a coating amount of the photosensitive silver halide per one side is from 0.01 g/m2to 0.45 g/m2in terms of silver amount; and (2) a crossover (%) is 30% or more, or when parallel light having the same wavelength as a main emission peak wavelength of the fluorescent intensifying screen is incident perpendicular to the surface of the photothermographic material, the parallel light component of transmitted light comprises 5% or more of the incident light. A photothermographic material for medical use having high sensitivity and high image quality is provided.
