Radiographic elements for medical diagnostic imaging exhibiting improved speed-granularity characteristics |
摘要 |
A radiographic element for medical diagnostic imaging is disclosed comprised of a transparent support and first and second silver halide emulsion layer units coated on opposite sides of the film support, each emulsion layer unit being comprised of a silver iodohalide tabular grain emulsion containing less than 5 mole percent iodide, based on silver. An improvement in speed in relation to granularity is obtained by the presence of tabular grains having {111} major faces, containing a maximum surface iodide concentration along their edges, and a lower iodide concentration within their corners than elsewhere along their edges.
