The images of the Siemens DSCT is very good, and I was reading that the radiation is not 2 times of the conventional 64 ct. How come they get this ?

Supposedly radiation dose is not 2X normal dose...but I think this is some sneaky marketing by Siemens. They even try to claim that it's 1/2 the dose...that's bold. But they make the comparison to older systems without ECG-dose modulation and filters -- which nearly every new system has had for the past 2 years. Xrays scattered in the body from one tube onto the other detector would actually necessitate a dose increase if you want to get the same noise level in your images.
