    Abstract: An optical system (3) illuminates a sample (4) with X-rays emitted from a radiation source (1). An oblique incident mirror allows the X-rays passed through the sample to be magnified and imaged at specified position. A detector (6) detects the X-ray image. A regulation unit moves detector, sample and optical system along the optical axis to regulate X-ray imaging magnification.

    Abstract: A radiographic magnifying device (4) suitable for use in radiation diagnostic apparatus comprises a cylindrical vacuum envelope (21), having at one end a photoelectric layer (7) and at the other a phosphor layer (8). A scintillator (5) is optically coupled by an optical device (6) such as a fiber plate, to photoelectric layer (7) and first and second focussing coils (11, 12) are arranged around the envelope (21) and means (9, 10) for generating an electric field to accelerate electrons emitted from the photoelectric layer (7) towards phosphor layer (8) are provided. A deflection device (14), preferably comprising two pairs of magnetic deflection coils, capable of deflecting electrons passing through the envelope is disposed about the envelope. The radiographic magnifying device produces a visible image as a result of the radiation impinging on scintillator (5) causing a light image to impinge on photoelectric layer (7) which emits electrons which impinging on phosphor layer (8) produce a visible image the magnification of which is determined by the currents in focussing coils (11, 12). A diagnostic apparatus can be formed using a combination of the radiographic magnifying device, a radiation source, a television camera and a display means, such as a picture monitor.

    Abstract: The radiation diagnosis device is used to obtain enlarged penetration images of organisms, and has a radiation source (1, 2), a radiogram enlarger (4), a television camera (17) and an image monitor (19). The radiogram enlarger consists of a cylindrical vacuum tube, a photoelectric layer, a phosphor layer (8), a scintillator (5), an optical coupling device, focusing coils, an electrical field generator, a deflecting device and a focusing current generator. A distinctive feature of the radiation diagnosis device is that it permits the observation of enlarged X-ray penetration images of organisms on the image monitor without destroying or damaging the organisms.

    Abstract: An X-ray image magnifying device characterized by comprising an illuminating optical system (3) for illuminating a sample (4) with an X-ray emitted from a radiation source (1), an object lens (5) composed of an oblique incident mirror consisting of a paraboloid of revolution and an ellipsoid of revolution to allow an X-ray passed through the sample (4) to be magnified and imaged at a specified position, an X-ray image detecting means (6) for detecting a formed X-ray image, and an imaging magnification regulating means for moving at least one of the detecting means (6), the sample (4) and the optical system (3) along an optical-axis direction to regulate the imaging magnification of an X-ray image. Consequently, an X-ray image magnifying device that uses an oblique incident mirror as an object lens enables changing of imaging magnification without interchanging an oblique incident mirror.

    Abstract: PROBLEM TO BE SOLVED: To provide a gas visible image pickup device for picking up a visible image of gas. SOLUTION: In this device, an X-ray outputted from a high output X-ray generator 10 is made incident on a reduced pressure vessel 20c via a connecting passage 30 to be irradiated to detecting object gas 20g in the reduced pressure vessel 20. When irradiating the X-ray to the gas 20g of a reduced pressure state, this gas visibly emits the light. An image pickup device 40 picks up a visible image of the gas.
