西门子双元ct（SIEMENS dual CT） By the end of 2005, SIEMENS had released the industrys first dual source CT, and became one of the most watched CT products at the recently concluded RSNA2005. What is the significance of this new CT? What impact will it have on clinical medicine? Will its emergence establish a new direction for the development of CT? With doubt began a dual CT adventure, and act as a guide to me more about related knowledge: the Radiological Society chairman Professor Qi Ji, vice president of SIEMENS medical CT global BerndOhnesorge, SIEMENS China Co. Ltd. Mr. medical system group vice president Mr Zhong Hanming, SIEMENS medical systems group CT products business the development of the general manager, Mr. Wei full CT sales manager Mr. Zhang Dahai. In recent years, with the development of multi-slice spiral CT, cardiovascular imaging has become one of the most potential fields of CT. Cardiovascular performance has also become a topic in the evaluation of the progress of multislice spiral CT technology. The experts began the introduction of dual source CT from cardiovascular images. CT and cardiovascular imaging Life throbbing heart is a problem of Radiology, in a very long period of time, radiologists with high heart rate, cardiac arrhythmia, heart can not grasp the relatively quiescent short cycle, had to rely on cardiovascular angiography and other traumatic examination method for cardiac imaging needs. In 1970s, when CT was first invented, it took 7 minutes for each scan of 360 minutes, mainly for the non motor organs of the head, lungs, and body. No one would have thought of using it for heart imaging, except for the shaggy haired scientific lunatic. 30 years CT has been moved from a passing of night, axial tomography developed into helical scanning, from single detector to detector, scanning speed, scanning range of each coverage expansion, cardiovascular CT (CardiacCT) never may develop into possible; development of ECG gated technology, multi sector
