徴とするＸ線テレビ透視撮像装置。An X-ray image tube that multiplies the brightness of the X-ray information that has passed through the subject on the tilting fluoroscopy table top and converts it into a visible light image, and a horizontal deflection circuit and a vertical deflection circuit that transmit the converted visible light image. By supplying the necessary sawtooth current to the horizontal and vertical deflection coils, the image pickup tube scans with an electron beam deflected in the horizontal and vertical directions and converts it into a video signal, and the converted video signal is converted into an optical image. In the X-ray television fluoroscopic imaging device equipped with a picture tube for displaying images, a top plate inclination angle detector is provided for detecting the inclination angle of the tilting fluoroscopic table top plate with respect to the gravity direction or the horizontal direction. In addition, a sawtooth wave phase changing circuit is provided which changes the phase of the sawtooth wave current supplied to the horizontal and vertical deflection coils of the image pickup tube based on the detection signal of this detector, and the output of this changing circuit is applied to the image pickup tube. An X-ray television fluoroscopic imaging device characterized in that the input is input to a horizontal deflection circuit and a vertical deflection circuit.
