Rotating-anode X-ray tube assembly and rotating-anode X-ray tube apparatus |
摘要 |
According to one embodiment, a rotating-anode X-ray tube assembly includes an X-ray tube, a stator coil, a housing, an X-ray radiation window, and a coolant. The housing includes a first divisional part which includes an X-ray radiation port and to which the X-ray tube is directly or indirectly fixed, and a second divisional part located on a side opposite to an anode target with respect to an anode target rotating mechanism and coupled to the first divisional part. A coupling surface between the first divisional part and the second divisional part is located on one plane, and is inclined to an axis, with exclusion of a direction perpendicular to the axis. |

1. A rotating-anode X-ray tube assembly comprising:
an X-ray tube comprising an anode target including a target layer which emits X-rays, an anode target rotating mechanism configured to rotatably support the anode target, a cathode disposed opposite to the target layer in a direction along an axis of the anode target and configured to emit electrons, and an envelope accommodating the anode target, the anode target rotating mechanism and the cathode; a stator coil configured to generate a driving force for rotating the anode target rotating mechanism; a housing comprising an X-ray radiation port opening in a direction perpendicular to the axis, and storing and holding the X-ray tube and the stator coil; an X-ray radiation window configured to close the X-ray radiation port and to take out the X-rays to an outside of the housing; and a coolant filled in a space between the X-ray tube and the housing and absorbing at least part of heat produced by the X-ray tube, wherein the housing includes a first divisional part which includes the X-ray radiation port and to which the X-ray tube is directly or indirectly fixed, and a second divisional part located on a side opposite to the anode target with respect to the anode target rotating mechanism and coupled to the first divisional part, and a coupling surface between the first divisional part and the second divisional part is located on one plane, and is inclined to the axis, with exclusion of a direction perpendicular to the axis. |
