Abstract

This overview article gives a short introduction into present status and future potential of multislice computed tomography. The main benefits of established 4- to 16-slice CT systems are larger volume coverage, better utilization of the X-ray tube output and above all improved transverse resolution. Spiral examinations with 16 submillimeter slices are a breakthrough on the way towards isotropic scanning for routine applications. ECG-controlled CT-examinations of the heart benefit from both the improved temporal and spatial resolution of the new generation of 16-slice CT systems. Compared to 4-slice scanners, cardiac examinations are clinically more robust. The most important potential for improvement of multislice cardiac CT is a further enhancement of temporal resolution which requires increased gantry rotation speed for robust clinical performance. Combined systems such as CT PET scanners will gain increasing importance in the near future. In general radiology the race for more slices will continue, finally leading to the introduction of CT systems with area-detectors.

摘要

这篇综述文章简要介绍了多层螺旋计算机断层扫描的现状和未来潜力。已成熟的4至16层CT系统的主要优势在于更大的容积覆盖范围、X射线管输出的更好利用,以及最重要的是横向分辨率的提高。采用16层亚毫米层厚的螺旋扫描是朝着常规应用的各向同性扫描迈进的一项突破。新一代16层CT系统改善的时间和空间分辨率使心脏的心电图控制CT检查受益匪浅。与4层扫描仪相比,心脏检查在临床上更稳定。多层心脏CT最重要的改进潜力是进一步提高时间分辨率,这需要提高机架旋转速度以实现稳定的临床性能。诸如CT-PET扫描仪等联合系统在不久的将来将变得越来越重要。在普通放射学领域,增加层数的竞争将继续下去,最终会引入采用面积探测器的CT系统。
