摘要： PURPOSE:To use effectively an image integrating processing apparatus, by, in a control system using the image integrating processing system, silencing quantizing noise and improving image clearness. CONSTITUTION:An image control apparatus 13 controls filter adjustor 14, light image intensifier adjustor 15 and X-ray adjustor 16. Further, when an X-ray penetration image of monitor TV 10 is brightened with halation, X-ray control volage and current is dropped by the adjustor 16. By this, X-ray energy to an X-ray penetration camera 3 is limited to a small value for silencing the quantizing noise. Further, by adjusting filter 6 and light image intensifier 8 by adjustors 14, 15, the clearness of image is improved. Thus, as the quantizing noise can further be silenced, effective use of the image integrating processing apparatus 11 can be achieved.

摘要： PURPOSE:To carry out an X-ray dynamic picture diagnosis, by providing a timing control part, controlling a cinecamera equipment and an X-ray television camera equipment synchronized with X-ray exposure, and enabling television- photographing and cine-photographing to be taken simultaneously. CONSTITUTION:Facing an X-ray tube 5 an image intensifier is disposed, whose fluorescent image is fed to the inputs of a cinecamera 11 and an X-ray television camera 6 through a half mirror 12. A control signals S2 is fed to the television camera 6, a control signal S10 is fed to the cinecamera 11, and a signal S8 is fed to a picture input interface 9, and further, a mode selector signal S1 and an X-ray demand signal S3 synchronized with the signal S2 are fed to a selector 2, and the outputs are given to an X-ray controller 3 and a high-voltage generator 4, then X-ray exposure is carried out. Consequently, only by one time exposure of an X-ray pulse, simultaneous photographing by the television camera 6 and the cinecamera 11 is possible and the dynamic analysis can be easily carried out.

摘要： PURPOSE:To compare an actual X-ray stop amount displayed on a monitor with an open amount by providing a display displaying the open amount of the stop detected by a video signal. CONSTITUTION:The image of a piclture picked up by a video camera 8 is converted into a video signal by a video camera controller 15, where the signal is divided into two; one is applied to a monitor 9 and the other is fed to a camera controller 14. Then, the camra controller 14 detects the shadow of the X-ray stop, operates to what degree in size the shadow corresponds on a camera 10 to control the aperture stop of the camera 10. The amount of the shadow or the amount other than the shadow is displayed on a display device 16. The actual X-ray stop amount displayed on the monitor is checked by displaying the stop opening amount on the display device in this way.

CONSTITUTION:X-rays are generated from an X-ray generating device 1, and X- rays which transmit an object to be photographed are detected like a two- dimensional plane by an optical system 4 to form a time series-like electric signal by an image pickup tube 5. Subsequently, correction is executed by a hardware filter 7 which provides an output by processing a one-dimensional filter for executing a correction based on a blur correcting filter function derived from a blur function in a system in advance, it is A/D-converted by an A/D converter 9, and thereafter, blurs in the one-dimensional scanning direction and the right angle direction are corrected by a digital arithmetic device 8, and a picture is outputted to an output device 10.

摘要： PURPOSE:To operate stably a high speed stereo X-ray photographing apparatus with a high speed by closing a high voltage switch mechanism for a shorter period than the time when each cathode is kept to electric potential where each cathode can emit electron currents. CONSTITUTION:When a pulse shaped control signal is applied from a controller 42, to a control grid of an electronic tube 41 in a bias switching switch mechanism 15 in the left side, electron currents are ready to be emitted from a cathode 23 in the left side, and high voltage switches 19, 20 are set, delayed by a prescribed period of time, simultaneously to ON state by means of a signal from its controller 21. Next, a voltage is applied to an X-ray tube 11, and electron currents are emitted only from the cathode 23 along with the emission of X-rays from a left side focal point. And, after said ON state of the high voltage switches 19, 20 is retained only during a prescribed period of time it returns to an OFF state with the completion of an X-ray radiation. And in the same way, a switch mechanism 16 in the right side is actuated, allowing the bias potential to be connected only during a prescribed period of time and to be returned again to the cut-off potential.

摘要： PURPOSE:To introduce an X-ray image on an X-ray TV set and two film cameras respectively, by changing an X-ray perspective image for right image or for left image into an optical image, and distributing and introducing said optical image by means of a half mirror which is rotatably disposed on an optical axis. CONSTITUTION:An X-ray image of a body to be tested is focussed on the input surfaces of image intensifiers I.I.3, and said image is changed into an optical image to be introduced into an optical system unit 4. While, the half mirror rotates synchronously with the shutter of cine-cameras 5 and 6, and stops for a while at a position where the cine-camera with the open shutter reflects the image toward the optical axis direction X-ray is radiated thereafter, and the half mirror rotates up to a position where the next cine-camera can reflect an image toward the optical axis direction. The optical image is distributed to each camera by means of the half mirror 4b, and a residual ray which is transmitted through the half mirror 4b is introduced into the TV camera and photographed.

摘要： PURPOSE:To obtain a stable tube voltage, by heating the filament of an X-ray tube by means of a square wave AC power which is synchronized with an exposure repeating frequency, and by conducting an X-ray exposure in the same phase as a tube current ripple. CONSTITUTION:The number signal of clock pulse of a switching period for a movie camera shutter is input into a down counter 15 from a photographing frame number setter 9 in response to a predetermined frame number. Accordingly, FF16 is reversed by synchronizing the opening and shutting of the movie camera shutter, and thereby transistors 18 and 19 are switched alternatively. While, the output four a single phase AC source 11 is stored in a power supply condenser 21 and a heat level setting signal which is PWA modulated by a pulse-duration modulator 28 from a heat level setter 27 is stored in a condenser 24. A square wave AC source is impressed to the filament of an X-ray tube 5 connected through switching of transistors 18, 19 to the secondary side of an insulating transfomers 12 and the X-ray photographing signal is synchronized with the filament heating wave form, so as to stabilize the tube current wave form during the photographing period.
