这篇文章主要介绍了关于python 读取DICOM头文件的实例，有着一定的参考价值，现在分享给大家，有需要的朋友可以参考一下

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：

ds = dicom.read_file(&#39;H:\Data\data\\21662\\2.16.840.1.113662.2.0.105002416.1489146183.701\CT\\CT#0#21662#E7AB693D.dcm&#39;)
print ds

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 = &#39;H:\Data\data\\21662\\2.16.840.1.113662.2.0.105002416.1489146183.701\CT\\a.dcm&#39;
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
>>[&#39;0.734375&#39;, &#39;0.734375&#39;]
