摘要
双源CT机是有2套数据采集系统的64层CT,具有图像信噪比更高、时间分辨率更高、射线吸收剂量更低、扫描视野大、覆盖范围广及双能量减影等优点,能否充分发挥这些优点与该设备装机前的准备工作密切相关。因此,从机房建筑、设备环境、设备供电、火情防护、射线防护及设备外围等方面,对如何做好双源CT机装机前的准备工作做了相应的探讨。
Dual source CT is a kind of 64 slices CT including two acquisition systems. It possesses such advantages as higher SNR of images, higher resolution of time, lower dose of radiation, bigger FOV of scanning, wider coverage of scanning and dual enrage subtraction imaging, etc. Weather these advantages could be brought into full play has great relationship with the preparations of dual source CT before its installation. The corresponding discussion is made in this text to see how to make preparations for dual source CT in different aspects such as room building, surrounding background, power supply, fire protection, radiation protection and periphery, etc.
