Expounding the Pitch,Thickness,Reconstructing Space of Multislice CT and Influencing the Imaging Quality

摘要: 多层螺旋CT间世大大提高了扫描速度,一次扫描能同时获得多个层而的图像,并且有足够的信息量进行图像后处理,但扫描参数的正确选择至关重要。本文就多层螺旋CT的扫描及重建参数螺距、层厚及重建间隔及对图像的质量影响进行阐述。

Abstract: With multislice CT appearing, the scanning speed was improved enormously. The images of multislice can be acquired simultaneously by once-through scanning, and sufficient informations were postprocessed. It was important that the scanning parameters were choosed rightly. The article expounds the pitch, thickness, reconstructing space of multislice CT, which influences the imaging quality.
