OverviewA 128-slice dual source CT scanner (Fig. 1) is equipped with two x-ray tubes and two corresponding detectors, mounted onto the rotating gantry with an angular offset of 94°.
Whatis the difference between 64 slice and 128 slice CT Scanner? The 128-slices CT scanners have more rows of detectors, which means that these systems provide larger volume coverage and shorter examination times. This is very useful in cardiac studies.
Theresults showed that the 256-slice CT generates a smaller dose than the 16-slice CT in all examinations. For volumetric cine imaging, we found an acceptable scan time would be 6 s to 11 s, depending on examinations, if dose must be limited to the same values as routine examinations with a conventional multidetector CT.
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.
Multipleslice CT scanners initially could take four separate images through each rotation, but technology has improved to the level that CT scanners can now take between 6 to 128 separate images in a singular rotation, meaning that it takes significantly less time to complete a CT scan.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.TTqbD.
