CT检查床有两种功能，1把病人送进扫描机架孔内，2把被检部位正确地固定在X线束辐射到的位置，在这种功能作用下，才能将兴趣区通过扫描、重建，成为要诊断的图像，根据我院GEPr0SPeedCT机五年多来检查床运行过程中出现的故障现象，进行分析及处理的过程予以报导，供同道参考。 The CT examination bed has two functions. One patient is sent into the scanning rack hole, and two parts to be examined are correctly fixed on the position where the X-ray beam is radiated. Under this function, the area of ​​interest can be scanned and reconstructed. , To become the image to be diagnosed, according to our hospital GE Pr0 SPeed CT machine more than five years to check the phenomenon of failure occurred during the bed operation, the analysis and processing of the process reported, for reference.
