Abstract: 回転陽極Ｘ線管が、陽極を有する。 その陽極の焦点トラックは、サドル軌跡の形状を持つ。 高出力ラインフォーカスを可能にする適切な陽極角が、陽極における焦点経路に沿って常に実現される。 Ｘ線管は、ＣＴスキャナ用であり、ガントリ回転の間、患者軸に沿った焦点スポットの移動を可能にする。 こうして、再構成によるコーンビームアーチファクトが回避されることができる。

Abstract: PROBLEM TO BE SOLVED: To provide an X ray generation apparatus whose operation rate is improved and a continuous X ray generation time becomes longer with the advantage of a longer life by vibrating a target in order to enlarge an effective electron colliding area without thickening the target. SOLUTION: A concentrated temperature rise in the target 9 by an electron collision is suppressed because generated heat is dispersed owing to the enlargement of an effective electron colliding area of the target 9 which is obtained as a colliding point of an electron beam B can be moved on the target 9 by vibrating the target 9. As a result, the evaporating of the target 9 can be decreased. Therefore, a life time of the target 9 can be increased without thickening the target 9, the operation rate of the X ray generation apparatus depending on the exchanging and adjusting of the target 9 can be improved, and the continuous X ray generation time becomes longer.

Abstract: PURPOSE:To accomplish an X-ray generating device which is embodied compactly and is unlikely to damage the target even with an X-ray output being increased. CONSTITUTION:A mechanism to reciprocate a counter-cathode (target 10) is furnished to shift the position on it where irradiated is made with electron beam 15. The reciprocating motion is generated by the attracting/repulsing forces acting between permanent magnets 11, 12 on the side ends of the target 10 and electromagnets 13, 14 arranged on both sides of them.

Abstract: A radiation generating apparatus includes a target base 110, a target 120, a holding assembly, an electronic beam generating device 140 and a first driving unit 160. The target is disposed on the target base. The holding assembly holds the target base and has an axial direction and a radial direction. The electronic beam generating device is adapted to generate an electronic beam, where the electronic beam is emitted to the target along the axial direction to generate a radiation. The first driving unit is adapted to drive the target base to move along the radial direction. The device may also have a second driving unit 132 and a rotation member 134, wherein the rotation member is connected between the second driving unit and the target base 110 and is configured to drive the rotation member and the target base to rotate along the axial direction. The driving unit may be adapted to vibrate along the radial direction.

Abstract: In an intermediate space between a rigid anode axle (1) and an anode plate (AP) (5) there is liquid coolant for carrying away heat onto the anode axle (AA), which protrudes into a vacuum-sealed casing (2). Bearings rotate an anode tube (4) on the AA, to which the AP is attached. Fitted radially regarding the AP, a cathode (6) directs an electron beam (8) onto the AP that radiates X-rays.

Abstract: A bearing assembly for a rotating anode x-ray device. The bearing assembly includes a shaft having a flange at one end for attachment of the anode thereto. The shaft defines front and rear inner races and includes a plurality of extended surfaces. Front and rear outer race elements define front and rear outer races, respectively, corresponding to the front and rear inner races, respectively, defined by the shaft. The front and rear outer race elements cooperate with the shaft to confine front and rear ball sets which facilitate rotary motion of the shaft. A spacer including extended surfaces assists in the positioning of the front and rear outer race elements in a bearing housing. The extended surfaces of the shaft and spacer, in conjunction with emissive coatings provided on various portions of selected components of the bearing assembly, facilitate a relative improvement in heat transfer out of the bearing assembly.

Abstract: An X-ray generating tube is disclosed, which tube is especially suitable for use in a computerised tomographic apparatus in which a spread of x-radiation is required to shift rapidly relative to the body of a patient under examination. The tube contains a rotating anode which is either reciprocated to-and-fro along the axis of rotation thereof or contains a shaped profile which scans along said axis.
