摘要： Fins are arranged on the rotating side of an X-ray computed tomography apparatus. The fins are rotated to generate airflow as the rotating side is rotated. This airflow serves to discharge wear debris to the outside of the X-ray CT apparatus, thereby preventing the wear debris from scattering toward an X-ray tube and support bearing. In consequence, in the X-ray CT apparatus provided with a slip ring, the wear debris produced in a contact space between the slip ring and a brush can be prevented from being scattered in the apparatus.
摘要翻译：翅片布置在X射线计算机断层摄影装置的旋转侧。当旋转侧旋转时，翅片旋转以产生气流。该气流用于将磨损碎片排出到X射线CT装置的外部，从而防止磨损碎片向X射线管和支撑轴承散射。因此，在具有滑环的X射线CT装置中，能够防止在滑环和刷子之间的接触空间中产生的磨损碎屑散布在装置中。

摘要： In a medical X-ray CT apparatus, a rotary portion is rotated, and a wind is produced inside the apparatus by the rotation of the rotary portion. An expanded cover portion is forced to vibrate by the wind, and noise is produced. The expanded cover portion is provided with at least one curved member including both ends. The curved member is arranged to extend along a virtual projection line obtained by geometrically projecting a virtual straight line connecting, to each other, the two ends fixed to an outer peripheral edge of an opening of the expanded cover portion onto a surface of the expanded cover portion, and the vibration of the expanded cover portion is reduced.
