Increasedspeed, detector size and sensitivity mean doctors can scan a heart, lung or brain with considerably less radiation than a scan with a 64-slice CT or a nuclear stress test. The 64-slice scanners required four to six heart beats to capture an image of the entire heart. The 256 can cover the distance in two heartbeats.
Whatis the difference between 64-slice and 128 slice CT? To reduce the radiation dose, it is important to use different methods with the scanner provided. Compared with 16-slice and 64-slice CT, 128-slice CT has more detectors, which means larger volume coverage and shorter scan times.
