对一个医生来说,在涉及辐射技术的高难度手术过程中,最糟糕的情况莫过于突然断电。精密的电子仪器和高分辨率的监视器使医生能够看到患者体内导管的清晰线路。如果突然断电,医生就无法看到患者体内的情况,必须等待电源恢复后,才能安全地取出患者体内的器械。即便是在最好的情况下,医院的发电机也要花费5分钟的时间才能使整个系统恢复运转。在此之前,医生不得不保持“凝固”的状态以避 For a physician, the worst case scenario in a difficult surgical operation involving radiation is a sudden power failure. Sophisticated electronics and high-resolution monitors allow physicians to see the clear lines of the catheter in patients’ bodies. If a sudden power outage, the doctor can not see the situation in the patient’s body, you must wait for the power to recover, in order to safely remove the patient’s apparatus. Even at the best of times, it takes five minutes for the hospital generator to get the entire system back on line. Prior to this, the doctor had to keep “frozen” state to avoid
