Abstract: Provided is a method for manufacturing a housing of a radiation detection cassette that can appropriately form a recess without a housing material depositing on an end mill or the like, in a case where a recess is formed by working the housing material formed of an alloy containing Mg and Li. A method for manufacturing a housing of a radiation detection cassette that houses a radiation detector in the housing includes preparing a housing material that is formed of an alloy containing Mg and Li and contains 0.1 mass % or more of Li, forming a recess using a working method other than cutting work on a surface of the housing material, and performing cutting work on the formed recess to shape the recess.

Abstract: 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.

Abstract: An X-ray film development device performs development, fixing, rinsing, and drying processes while transporting an exposed X-ray film. A rinsing unit is provided with a light source, which illuminates the X-ray film during transportation, and a reading unit, which receives the passing light and reads an image recorded on the X-ray film. The image signal from the reading unit is processed by a display device (CRT, LCD, etc.), and the film image can be provided to the doctor or patient without waiting until the film dries.

Abstract: This invention pertains to novel methods of radiography and novel screen-film cassettes with wide exposure latitude and/or high film contrast for use in radiography. The materials and methods of the subject invention can be used in mammography. In a specific example, this invention concerns the design of novel screen-film cassettes which can use at least one phosphor screen and multiple x-ray films in a single cassette. When used in mammography, this novel design enables additional breast images to be obtained on the faster, or slower, speed film from the same x-ray exposure used to produce a normal breast image on the normal speed film. These additional breast images provide high contrast information on the dense regions of the breast and in the edge areas of the compressed breast. These dense regions currently cause many missed diagnoses in breast cancer screening.

Abstract: An instant photo film pack contains has a light-tight bag, which contains a stack of ten photo film units of a self-processing type in a light-tight manner. The light-tight bag has a bag component constituted by one belt-shaped sheet, and a tab projecting from the bag component. The bag component is formed by attaching one portion to another in a peelable manner. When the tab is pulled in one direction, attachment of the bag component is peeled, to strip the bag from the photo film units in a form of the belt-shaped sheet.

Abstract: An image media assembly comprising: a donor element, a receptor element, and means for maintaining at least the elements in a predetermined position wherein one element overlies the element, said means including a vacuum present between the elements.

Abstract: A device for developing and fixing a dental radiography plate includes a casing of flexible, impermeable material which is sealed around its entire perimeter and has first and second compartments interconnected by a flat duct. The first compartment contains a radiographic plate and the second compartment contains a sachet of a liquid for processing the plate. The sachet is adapted to release the liquid when its pressure exceeds a predetermined value as a result of the compression of the sachet.

Abstract: A film cassette designed to receive photosensitive film in a light protective envelope and maintain lighttight integrity while removing the protective envelope includes means for bringing a light emitting enhancer screen into intimate contact with the photosensitive film during exposure to x-ray photography. The back of the photosensitive film may be brought into intimate contact with a film or sheet of specimen-containing radioactive or radiation generating material.

Abstract: The invention relates to an X-ray apparatus with a motor-driven movable part. The drive takes place via a shaft, which is mounted in a bearing, the bearing forces of which are measured by a measuring device.

Abstract: A film carrier light-proof case, whose envelope comprises a first portion enclosing a radiographic film, a second portion enclosing at least one small bag which contains chemical products in a liquid state for the development and fixing treatments of the film and means for intentionally tearing the bag, and a connection portion between these two portions of the envelope, and in which each bag comprises a first extension which starts laterally from an end of the bag, is bent along the bag and projects through the end of the second portion of the bag, and also comprises a second extension which starts centrally from the same end of the bag and extends along a part of the length of the second portion of the envelope in a direction parallel to the first extension, and the tearing means consists of an elongate member made of a stiff material, bent on itself to enclose between its own two branches the second extensions of the bags, and projecting beyond the length of the second portion of the envelope to form two t

Abstract: A radiographic apparatus for facilitating insertion of a radiographic element on a carrier into the retractable opaque envelope of a film unit for exposure purposes, and for facilitating its later removal, includes a housing having a light tight chamber for receiving the carrier and film unit arranged in superposed relation therein. When the housing is in an upright loading position and the envelope is retracted, gravitational force urges the carrier into contact with the negative sheet so that both are enclosed when the envelope is moved back to its closed position. During removal operations, the housing is inverted, allowing gravitational force to urge the carrier away from the negative sheet so that the envelope passes therebetween when returned to its closed position, leaving the carrier outside of the envelope.
