Abstract
A stimulable phosphor sheet for radiation image recording and reproducing method is composed of at least two partitioned stimulable phosphor films laminated one or another [the partitioned stimulable phosphor film is composed of plural partitions that divide the stimulable phosphor film on a plane thereof to give plural stripe sections, and a stimulable phosphor layer placed in each stripe section] in such manner that the partitions of one stimulable phosphor film are arranged to cross the partitions of another stimulable phosphor film.
Claims13
A stimulable phosphor sheet for radiation image recording and reproducing method comprising the steps of recording a radiation image as a latent image, irradiating the latent image with stimulating rays to release stimulated emission, collecting the stimulated emission, and electrically processing the collected emission to reproduce the radiation image, comprising at least two partitioned stimulable phosphor films laminated one on another, the partitioned stimulable phosphor film comprising plural partitions that divide the stimulable phosphor film on a plane thereof to give plural stripe sections, and a stimulable phosphor layer placed in each stripe section, in such manner that the partitions of one stimulable phosphor film are arranged to cross the partitions of another stimulable phosphor film, wherein the partition of the stimulable phosphor film has a light-scattering length for the stimulating rays which is shorter than that of the stimulable phosphor layer.
A process for producing a stimulable phosphor sheet comprising at least two partitioned stimulable phosphor films laminated one or another, the partitioned stimulable phosphor film comprising plural partitions that divide the stimulable phosphor film on a plane thereof to give plural stripe sections, and a stimulable phosphor layer placed in each stripe section, in such manner that the partitions of one stimulable phosphor film are arranged to cross the partitions of another stimulable phosphor film, which comprises the steps of:
- producing plural stimulable phosphor films and plural partition films;
- laminating the stimulable phosphor films and the partition films alternately, to produce a laminate block;
- slicing the laminate block perpendicularly to the plane of the phosphor film, so as to give plural partitioned stimulable phosphor films;
- laminating the plural partitioned stimulable phosphor films in such manner that the partitions of one stimulable phosphor film are arranged to cross the partitions of another stimulable phosphor film;
- and
- heating the laminate under pressure.
