CT Working Principle
Image display
X-ray generation
Data acquisition
Reconstruction and post-processing
Conventional Scanning
◎ Scanning speed is restricted because of non-continuous scanning.
Spiral Scanning
Spiral Scanning = Volume Scanning
Working Principle of Spiral CT Scanner
◎ Continuous rotation of X-ray tube and detectors
◎ Continuous emission of X-ray
◎ Continuous couch move-in at an even speed
◎ Continuous data acquisition
Advantage of Spiral Scanning
Scanning speed is
increased greatly

Advantage of CT-C3000
Advantage of Metal Tube
Advantage of CT-C3000
Advantage of metal tube
◎ Large heat storage capacity, high heat dispassion
and strong capability of spiral scanning
◎ Increase images quality and extend service life of
tube with restraining electron radiation.
Advantage of CT-C3000
Advantage of metal tube
Large range continuous scanning can be achieved with
175mA and 80s.
Advantage of CT-C3000
Dual focus technique
Advantage of CT-C3000
Contrast the large focus with the small one
Large focus
Small focus
Advantage of CT-C3000
Heel effect of focus
◎ Focus of electron beam on the
anode target is the same with heel
on the floor.
◎ Sand blast will appear on anode
target because of small focus.
◎ Image quality will be effected.
Advantage of CT-C3000
