Unfortunately, there's a tradeoff: each imaging session exposes the patient to radiation. Too much radiation can be problematic.
The article does mention lower exposure but it's not clear whether it's just shorter in time (and more intense) or is the total level of radiation actually lower.
- wyldfire 12y agoThe dose is primarily a function of the power delivered to the X-Ray source, the size of the beam and the scan's duration. The big features of this device are coverage (160mm) and rotation speed (mostly dose neutral). If you were imaging 160mm before you had to use multiple sequential scans, so the dose is not significantly different from that scenario. Revolution has similar or superior (meaning less) dose than GE's previous high end scanner. GE's high end scanners tend to offer better dose than the competition.
