Prospectivelygated 64‐slice CT coronary angiography (CTCA) may be contraindicated for heart rates (HRs) over 65 beats per minute (bpm) due to reduced diagnostic sensitivity. Newer CT scanners typically provide 128 or more slices and superior temporal resolution compared with older models; consequently, diagnostic accuracy for current Wepresent an evaluation of a recently introduced 64-slice CT (64SCT) system, which makes use of a periodic motion of the focal spot in the longitudinal direction (z-flying focal spot) to double the number of simultaneously acquired slices. 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).
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.
