摘要： Die Erfindung betrifft ein Röntgengerät mit einer Drehanodenröntgenröhre, mit einer Einrichtung zur Überwachung der Drehzahl eines Drehan-odenantriebsmotors der Röntgenröhre, mit einer Sensorschaltung zur Ermittlung eines vom Phasenwinkel zwischen einer Bezugsspannung und einem dem Motor zugeordneten Strom abhängigen Winkelsignals, mit einer Vergleichsschaltung zum Detektieren der Änderung des Winkelsignals, welches als Kriterium für die Motordrehzahl dient, sowie mit einem Frequenzumrichter. Dadurch, daß eine Einrichtung zur Bildung eines kurzzeitigen Tastsignals für die Veranlassung einer Erniedrigung der Frequenz des Drehanodenantriebsmotors vorgesehen ist, ist die Einrichtung auch für solche Induktionsmotoren geeignet, bei welchen zwischen Stillstand und Betriebsdrehzahl nur eine geringe Phasenwinkeländerung gemessen wird.

摘要： A toroidal x-ray tube (I) is supported (II) for rotation about a horizontal axis (170) , translation along a vertical axis (172) , and translation along a horizontal axis (174) . The x-ray tube includes a toroidal housing (A) , an annular anode (B) , and a cathode (C) which rotates a beam of electrons around the annular anode. A plurality of parallel connected voltage sources (90₁, 90₂, ..., 90 n ) provide a sufficiently high bias voltage between the electron source and the anode that x-rays are generated. The x-ray beam passes through a compensator crystal (62) , an annular window (20) , a collimator (132) , through a subject received in a central bore (26) of the x-ray tube, and impacts an arc segment of radiation detectors (130) . The x-ray detectors are stationarily mounted outside of the plane of the annular window (FIGURES 2 and 7), nutate into the plane of the windows opposite of the origin of the x-ray beam (FIGURE 6), rotate in part (FIGURE 9) or rotate in full (FIGURE 8). Angular position monitors (58, 154) determine the angular position of the cathode assembly, hence the x-ray beam, and the angular position of the detectors in the rotating detector embodiment.

摘要： X-ray images are produced on a monitor display screen (32) by situating the subject between a detector (13) having a minute x-ray sensitive area and an x-ray source (12) having an extensive anode plate (18) on which an x-ray origin point is swept in a raster pattern similar to the raster of the display monitor. Operating parameters of the x-ray source are controlled by digital data processing circuits (43) which enable magnification of operator selected areas of the image by reducing the size of x-ray source raster pattern and repositioning of the raster pattern on the anode plate in response to operator actuation of one or more computer input devices.
In the preferred form, the system also enables image enhancements and control of image characteristics such as contrast and brightness in response to actuations of the input devices or in response to programming. X-ray exposure and image acquisition time may be reduced by operator selection of only specific areas of particular interest for high resolution scanning. In the preferred form, the apparatus can detect a particular gray level in the image data and relocate the scan to image the region where the gray level is found. This enables fixed imaging of a moving object.

摘要： The rotary cathode X-ray tube equipment of the present invention is constructed so as to permit radiation of X-ray from all directions with respect to the whole circumference of a subject, and is used for x-ray CT. The equipment of the invention is constructed to prevent an X-ray radiation window 40 of a low strength from being influenced by atmospheric deformations of a vacuum vessel 1 or by machining and assembling errors, for example by using a joint portion disposed between the X-ray radiation window and an inner ring and having both a surface perpendicular to a rotational axis of a rotary member and a cylindrical surface parallel to the rotational axis, a face seal formed on the surface of the joint portion perpendicular to the rotational axis, and an axial seal formed on the cylindrical surface of the joint portion parallel to the rotational axis.

摘要： An anode (A) closes one end of an evacuated envelope (C) and a cathode end plate (22) closes the other. A cathode assembly (B) is mounted on a bearing (40) in the evacuated envelope such that the envelope and cathode can undergo relative rotation. A motor (38) rotates the anode and envelope while a pair of magnets (44, 46) hold the cathode assembly stationary. Bearing (40) functions as a current path from a current source (72) to the primary windings of a transformer (58) . Another bearing (94) provides a return current path from the transformer to the current source. The secondary windings of the transformer are connected with a cathode filament (52) . The transformer enables a relatively low ampere current to pass through the bearings to limit cathodic damage to the bearings, yet provides sufficient amperage to the filament to cause thermionic emission. The bearings provide a direct transfer of current which does not degrade the vacuum in the envelope in such a manner that the current through the cathode filament can be measured directly from outside the envelope.
