Whilesome experts have argued that a 16-slice system is sufficient from a practical standpoint, a closer examination of 32- and 64-slice systems offers new and superior clinical benefits over and above 16-slice technology, especially in imaging of the coronary arteries and in multiphase and functional studies.
Forthe 4-slice example, this corresponds to a pitch of 3/4 = 0.75; for a 16-slice scanner, the pitch is 15/16 = 0.9375; and for a 64-slice scanner, the pitch is 63/64 = 0.9844. Note that such pitches move closer to 1 (smaller fraction of beam overlap) as the number of simultaneously acquired slices increases (more information regarding this
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.
