The invention relates to a system having a scanner and a memory layer. The memory layer comprises particles for storing X-ray information items, that can be excited by a stimulating radiation to emit an emission radiation corresponding to one of the X-ray information items and that are embedded in a medium and are distributed over the entire thickness of the memory layer. The scanner comprises an irradiating device for irradiating a linear region on the memory layer and a detector for the positionally resolved detection of emission radiation emitted by the memory layer along the linear region. To increase the sharpness of the X-ray information items to be detected with low losses in the intensity of the emission radiation, the medium can at least partially absorb components, directed both perpendicularly and parallel to the plane of the memory layer, of the emission radiation emitted by the individual particles.

System comprising a scanner and a memory layer, and a memory layer for storing X-ray information items

A sheet or foil comprises a layer unit, divided into at least two layers: a layer A, being a layer of parylene and a layer B, wherein layer B, optionally present at both sides of layer A, is characterized in that it comprises an organic coating having at least one phosphoric acid ester compound.

Scratch resistant moisture-protecting parylene layers

A packed phosphor screen or panel consisting of at least one flat square or rectangular screen or panel, optionally packed apart in a wrapper foil, and a sealed package, wherein said package is layered in form of an asymmetrical barrier layer foil, said foil comprising an inner flexible thermoplastic polymer layer and an outer polymer layer in adhesive contact with an aluminum layer situated inbetween said inner flexible thermoplastic polymer layer and said outer polymer layer, wherein said foil is characterized by adhesive forces, between said outer polymer layer and said aluminum layer, of more than 2.5 N/mmfollowing DIN 53 357, by a permeation to water vapor of less than 0.01 g per sq.m. in an environment having a temperature of 23&#xb0; C. and a relative humidity of 75% RV for 24 hours following DIN 53 122, and by a permeation of less than 0.01 cmper sq.m. per 24 hours and per bar for each of oxygen, carbon dioxide and nitrogen following DIN 53 380 (ISO 2556, ASTM D 1434).

Packed storage phosphor screens or panels

A cassette assembly comprising an X-ray cassette, with a tube side and a cover, and an intensifying screen wherein the cassette assembly further comprises a compensation element adapted to the intensifying screen so as to have a cassette assembly with predetermined X-ray absorption.

Cassette assembly for use with roentgen apparatus with automatic exposure control

A binderless stimulable phosphor screen comprises a vapour deposited storage phosphor layer on a support and a protective layer, preferably radiation cured, wherein the vapour deposited phosphor is needle shaped and the phosphor needles have a length, L and voids between them and wherein said protective layer fills said voids for at most 0.10 times L.
