目前CT、MRI、DSA及ECT机的使用单位很多,发挥这些机器的效益,减少停机使病员得到及时诊断,已经引起有关领导和操作人员的高度重视。由于缺少洁净技术知识,一些单位只考虑温度要求,而忽视了洁净空气是保证上述机器的关键部件——电子计算机正常运转的另一重要条件。 At present, CT, MRI, DSA and ECT machines are used in many units, giving full play to the benefits of these machines and reducing downtime so that patients can be diagnosed promptly. This has drawn great attention from leaders and operators concerned. Due to a lack of clean technical knowledge, some units only consider the temperature requirements and neglect the fact that clean air is a key component of the above machines - another important condition for the proper operation of electronic computers.
