摘要:
A laminate comprises a stimulable phosphor layer, which is capable of storing radiation image information, and which is capable of emitting light of an intensity proportional to the radiation image information when being exposed to secondary stimulating rays, a response speed converting fluorescent substance layer, which is capable of converting the light emitted by the stimulable phosphor layer into light having a life time longer than a light emission life time of the light emitted by the stimulable phosphor layer, and a photo-conductor layer, which is capable of exhibiting electrical conductivity when being exposed to the light obtained from the conversion performed by the response speed converting fluorescent substance layer. The laminate and an electroluminescent layer, which is capable of emitting the secondary stimulating rays with voltage application, are overlaid one upon the other and combined with each other into an integral body.

A neutron conversion foil for being used in a neutron detector includes a substrate having a first and second side. The substrate is covered at least on one of the first and second sides with a neutron conversion layer made of a neutron reactive material and being capable of capturing neutrons to thereafter emit light and/or charged particles. The neutron conversion foil is transparent to light such that light originating from the conversion of neutrons can pass through one or several of the neutron conversion foils and thereafter be collected and detected by a light sensing device.

A screen panel for converting X-rays into light photons includes a rigid foam plate (2), a first layer (1) of composite material located on one face of the rigid foam plate (2) and a second layer (3) of composite material located on the other face of the rigid foam plate, parallel to the first face. The screen panel applies, for example, to medical radiology and to non-destructive testing of nuclear waste storage packages.

In a flat image detector and method for the generation of medical digital images, the flat image detector is in particular suitable for a medical X-ray device and equipped with at least one active matrix (MX, MX2) made up of pixel-readout units, wherein the light generated in the scintillator (SZ) can be read out on both sides in the direction of the incoming X-ray radiation (R) in front of and behind the scintillator, with the aid of such an active matrix in each case arranged on each side of the scintillator.
摘要:
A preparing method of a radiation image conversion panel comprising: forming a stimulable phosphor layer on a support while the stimulable phosphor layer being unformed on a peripheral portion around the stimulable phosphor layer on the support; and sealing the stimulable phosphor layer by superimposing a protective layer on the support formed thereon the stimulable phosphor layer while providing an adhesive agent on the peripheral portion, wherein the sealing step is conducted under a condition controlling humidity so that a moisture content of the stimulable phosphor layer is lower than the moisture content maintaining equilibrium with an atmosphere having a water partial pressure of 2.66null103 Pa.
摘要:
In a radiographic image intensifier having an input window, and a method for its production, an intermediate layer is deposited on a substrate for a luminous layer, thereby smoothing the surface of the substrate. This intermediate layer serves to smooth the surface of the substrate and is thus a good base for a uniform growth of the crystal structure of the luminous layer.
