PHOTOSENSITIVE PHOTOGRAPH MATERIAL OF HALOGENATED SILVER HAVING REINFORCED IMAGE QUALITY FOR QUICK PROCESSING IN MAMMOGRAM METHOD

摘要

PURPOSE: To provide a silver halide photographic sensitive material for application in the field of mammography having a diagnostic value improved by intensified sharpness. CONSTITUTION: A silver halide crystal to be used in this material exhibits fogging level, toe contrast and overall contrast which are the image quality not substantially affected by processing conditions. The coating amt. of the silver halide crystal in the emulsion layer can be decreased to the amt. to ensure a preservable property of 10 to 20 years under ordinary storage conditions. The X-ray material is adequate for rapid processing without the loss of its sensitivity within a processing cycle of 45 seconds or 38 seconds and allows the use of a processing soln. not contg. a hardener.
