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. 128Slice and higher. These 128-slice or higher CT scanners are the top-of-the-line CT scanners you will find. Up to 320 slices, these machines can provide a full-body scan in mere seconds. Thanks to its incredible speed and accuracy, specialty practices generally invest in these costly machines. 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 CTscanners are often classified in terms of "number of slices", such that a "64-slice scanner" is regarded as superior to a "32-slice scanner". However, it is important to understand the distinction between "number of slices" and "number of detector rows". Philipsbrilliance CT phantom with Philips ingenuity 128-slice low-dose CT scanner was chosen for this study. CT number linearity, CT number accuracy, slice thickness accuracy, high-contrast resolution, and low-contrast resolution were calculated and estimated computed tomography dose index volume (CTDI vol) for all the mAs values were recorded. .
