Electron beam CT

Electron beam CT (ultra-fast CT) uses electron beams to penetrate the human body and rapid bed movement to complete the scan. Its fastest scanning speed is 50ms/layer. Overall, it is superior to spiral CT scans. The main scanning range is larger than spiral CT in unit time. The artifacts generated by movement are less than that of spiral scan. The imaging of cardiovascular contrast is better than that of spiral scan, but this expensive equipment is still rare in China.
