颅脑CT扫描技术方法的改进

Improvement on the scanning technique of skull computerized tomography

本文阐述了在颅脑计算机断层射线摄影的扫描过程中,改变扫描层平面距离的情况,即把该距离由10mm增加为11mm,从而形成一个宽1mm的未扫描空间。作者认为,由于一般的CT设备空间解像力低,形成的像素尺寸为1.0×1.0mm,因此,这些未扫描区不会影响诊断。

This paper reports a modification of distance between scanned planes of layers with a thickness of 10mm during skull CT radiography, namely an increase of planes distance from 10mm to llmm, thus Leaving a non-scanned space of 1mm width. The authors explained that the low spacial resolving power of typical CT equipment can offer a pixel size of 1. 0×1. 0mm, so these non-scanned spaces may not affect the diagnosis.
