    • In an X-ray imaging apparatus, unwanted electron charges caused by pulsatory X-ray trailing edges are eliminated from an X-ray image signal of a biological body under medical examination. The X-ray imaging apparatus comprises: an X-ray generator for generating a plurality of pulsatory X-ray beams; an X-ray controlling unit for supplying an X-ray projection controlling signal to the X-ray generator in order to project an X-ray pulse beam having a predetermined pulse width to a biological body under medical examination from the X-ray generator, thereby producing an X-ray image of the biological body under medical examination; an optical converter for converting the X-ray image into a corresponding optical X-ray image signal of the biological body under medical examination; an imaging unit for imaging the optical X-ray image signal derived from the optical converter to store the imaged optical X-ray image signal as electron charges therein; a driving unit for driving the imaging unit in such a manner that only electron charges produced while projecting the X-ray pulse having the predetermined pulse width to the biological body in response to the X-ray projection controlling signal, are read out as an effective X-ray image signal of the biological body under medical examination; and, a display unit for displaying thereon an effective X-ray image of the biological body under medical examination in response to the effective X-ray image signal.

    • A recording member having a predetermined substrate, and a thin film which is formed on the substrate and which is formed with recesses or pits for recording information when irradiated with a working beam, characterized in that said thin film is formed of an inorganic material which contains at least arsenic, selenium and tellurium, and that a distribution of either of said Se and said Te decreases from a part near the surface of said thin film towards a central part thereof, while a distribution of said As increases from a part near the surface towards said central part, is disclosed. This recording member can afford a high signal-to-noise ratio and a long lifetime. It is preferable that the distribution of said Se decreases so as to be at least 50 atomic-% in terms of the content of said Se in a part being the closest to the surface of said thin film and to be at most 40 atomic-% in terms of the average content of said Se over the whole thin film, and that the distribution of said As increases so as to be at most 15 atomic-% in terms of the content of said As in the closest part and to be 5 to 35 atomic-% in terms of the average content of said As in said whole thin film. The Se-Te-As-based material may well be doped with at least one element selected from the group consisting of Ge, S, Tl, Sn, Pb, In and Ta, within a range of 2 to 15 atomic-%.
