Abstract
Computed tomographic (CT) image resolution and quality were evaluated utilizing varying
scan protocols with accelerated image acquisition.
A resolution phantom with hole diameters from 0.2 to 1.0 mm was scanned in axial,
coronal, and sagittal plane using a 64-slice multidetector CT with varying scan parameters.
No relevant differences in image resolution and quality were detected between the
fastest scan protocol, with the shortest rotation time and highest pitch, and the
slowest protocol.
Accelerated CT protocols resulted in diagnostic images with adequate resolution and
quality.
