摘要： An X-ray CT apparatus is provided, having a function for deciding an X-ray imaging condition prior to scanning, the X-ray imaging condition allowing an acquisition of contrast to noise ratio appropriate for identifying a diagnostic object. Prior to the real scan, a three-dimensional model of an object is estimated from scanogram projection data of the object, a contrast to noise ratio enabling identification of the diagnostic object is calculated, based on the diagnostic object size set by an operator via an operating device when planning the scan, the three-dimensional model, and a standard imaging condition that is stored in a storage device. Then, an optimum irradiated X-ray condition (tube current and tube voltage) is calculated for achieving the contrast to noise ratio enabling identification. The X-ray condition being calculated is displayed in the form of information such as image SD value and exposure dose, under the calculated X-ray condition and under other condition.

The inventive X-ray generator with rotating anode comprises: a balancing device which is integrated in the X-ray generator and which includes a control device which is connected to the vacuum tank, and an actuating device which is connected to the rotor and which includes at least two compensation masses capable of being angularly displaced relative to each other, by means of the control device; a vibration sensor for detecting the vibrations of the X-ray generator; a position sensing device for detecting the position of the compensation masses; and a controller which is coupled to the balancing device and controlled by a microprocessor, for controlling the balancing device which is configured to calculate an imbalance, and which can move the compensation rings, via the control device, so as to reduce vibrations induced by the imbalance. The calibration is carried out by generating an imbalance vector, by moving in a specific manner one compensation mass at an angle α or by a specific distance relative to the axis of rotation.

摘要： In an X-ray tube with a hydrodynamic slide bearing, an electron beam is caused to strike the focal point track area F on its rotary anode, which then emits X rays. An X-ray emission control device that sets the conditions for emitting the X rays stores as data the rises and drops in the temperature at the electron beam incident point and the other part on the focal point track surface of the anode. On the basis of the data, the input permission or inhibition conditions for the X-ray tube at every moment are calculated and the resulting conditions are displayed on a display unit. As a result, it is possible to perform a computing process in advance to determine whether or not X rays can be emitted under specific conditions without a permitting the rotary anode in the X-ray tube with a hydrodynamic slide bearing to melt and then display the results, thereby enabling a safe, efficient photographing control.

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 (0) which rotates a beam of electrons around the annular anode. A plurality of parallel connected voltage sources (90.sub.1, 90.sub.2, . . . , 90.sub.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 (FIGS. 2 and 7), nutate into the plane of the windows opposite of the origin of the x-ray beam (FIG. 6 ), rotate in part (FIG. 9 ) or rotate in full (FIG. 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： A toroidal x-ray tube housing (A) has an evacuated interior. An annular anode (B) is connected with the housing closely adjacent the window such that a cooling fluid passage (12) is defined in intimate thermal communication with the anode. A cathode assembly (32) is mounted within the evacuated housing or an annular ring (30) that rotates an electron beam (22) around the large diameter annular anode. In the embodiment of FIGS. 1 and 2, the annular ring is magnetically levitated (40) and rotated by a motor (50). A collimator (62) and filter (64) are rotated with the cathode assembly closely adjacent an electron emitter or cathode cup (32) such that the generated x-rays are collimated and filtered within the x-ray tube. Preferably, a plurality of cathode cups (120) are provided, whose operation is selected by a series of magnetically controlled switches (76). The cathode cup is insulated (106) from the annular ring and isolated by a transformer (104, 112) from the filament current control switches. In the embodiment of FIGS. 4-6, the cathode assembly (C) includes a multiplicity of stationarily mounted electron cups (120) which are selectively actuated to rotate the electrode beam by a switch (130). An electron beam scan control (134) may bias the potential applied to grids (124, 126) to scan the electron beam generated by electron emitter over a commensurate arc length of the anode with the arc length of the emitter. In the embodiment of FIG. 7 , multiple anode surface as well as multiple cathode cups are provided.
