Heat accumulation in the tube housing appears to be an important contributory factor in the failure of X-ray tubes in computed tomography scanners. Additional tube cooling provided through air-conditioning of the gantry has resulted in a tube lifetime increase factor of 4.
管套中的热量积聚似乎是计算机断层扫描仪中X射线管故障的一个重要促成因素。通过对机架进行空调制冷来额外冷却X射线管，使X射线管的使用寿命提高了4倍。
