BH 640 slice CT has the lowest radiation ever in a CT scan. So what?

Radiation is a leading cause of cancer genesis. Frequent scans in low slice CT (3, 32, 64 slice CT) carry a higher risk. Long scan times in a low slice CT—even 5 minutes in a machine—give notable radiation. BH 640 does a full body scan in 9 seconds with as much radiation as an annual mammogram. Technology advances for a reason.
