pubmed:abstractText	This paper studies the helical CT low-contrast resolution and its influencing factors by experimental analysis. The CT low-contrast resolution increased with mA, kV, slice thickness, scan time and FOV, and decreased with matrix, pitch and thickness of the scanned objective. The reconstruction algorithm of high resolution results lower low-contrast resolution. Mostly helical image low-contrast resolution is slightly lower than axial image. It's very important for us to understand CT low-contrast resolution and its influencing factors for the correct evaluation of the performance of CT scanner.
