PHOTOFLUOROGRAPHIC CHAMBER Russian patent published in 2011 - IPC A61B6/00 G01T1/00 G21K4/00 

FIELD: measurement equipment.

SUBSTANCE: invention refers to medical technology, and namely to x-ray photofluorographic devices. Photofluorographic chamber includes light-tight housing protected with lead, with inlet opening covered with the plate from radiotransparent and light-tight material. Flat-shaped screen adjoins it. Screen consists of substrate, binding layer and luminescent material. High-speed lens and photorecorder is installed inside housing. Base of fibre-optic plane-parallel plate from dense flint glass, which is optically adjacent to the lens, adjoins the luminescent material. Optic fibres of the plate pass at angle α=arctg f/r to plane of luminescent material, where f - distance from axial point in plane of field stop of lens to luminescent material in direction of central ray, and r - distance from intersection point of central ray of lens of plane of luminescent material to optic input of fibre channel.

EFFECT: use of invention will allow decreasing radiation exposure on a patient.
