用dicompyler软件打开dicom图像,头文件如图所示:
当然也可以直接读取:

发现一套图的第一张和最后一张的slice thickness往往和中间层的值是不同的。

path = 'h:\data\data\\21662\\2.16.840.1.113662.2.0.105002416.1489146183.701\ct\\a.dcm' slices = dicom.read_file(path) spacing = slices.pixelspacing |
读取头文件信息方法:
slices.上图头文件中的name列。
这时要注意的是,name大小写不变,去掉空格,去掉符号,比如括号。
举例:

origin = slices.softwareversions print origin >>corvus 6.4 |

spacing = slices[ 1 ].pixelspacing print spacing >>[ '0.734375' , '0.734375' ] |
以上这篇python 读取dicom头文件的实例就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持服务器之家。
