摘要： A process of preparing a photographic emulsion having radiation-sensitive silver iodohalide grains. Iodide is introduced into the grains by releasing iodide ions from iodate (IO.sub.3.sup.-). Release of iodide ions from the IO.sub.3.sup.- is employed to enhance the uniformity of iodide availability during emulsion preparation, either during grain precipitation or subsequent halide conversion. The process of the invention is in one preferred form directed to the partial halide conversion of tabular grains. A speed-granularity advantage is demonstrated.

摘要： A digital radiographic detector having a radiation sensing element with a particulate material dispersed within a binder composition, wherein the binder composition includes a pressure-sensitive adhesive, wherein the particulate material, upon receiving radiation of a first energy level, is excitable to emit radiation of a second energy level, either spontaneously or in response to a stimulating energy of a third energy level. There is an array of photosensors, each photosensor in the array energizable to provide an output signal indicative of the level of emitted radiation of the second energy level that is received. The radiation sensing element bonds directly to, and in optical contact with, either the array of photosensors or an array of optical fibers that guide light to the array of photosensors.
