Theobjective of this study was to evaluate the performance of low-dose 128-slice CT scanner with different mAs values. Materials and methods: Quantitative study was carried out at different values of mAs. Philips brilliance CT phantom with Philips ingenuity 128-slice low-dose CT scanner was chosen for this study. 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. 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. 16 64, 128 and 256 Slice CT Scanners - Assessing the Costs vs. Benefits. Cost and Benefits of Various CT Scanner Slice Options. CT scanners can be of great benefit to most healthcare providers due to their ability to capture high-resolution diagnostic images at a fast rate ( the scanner's speed makes it a especially beneficial in the ER). 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. pyeY.
