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.dcmslices = 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.SoftwareVersionsprint origin>>CORVUS 6.4

spacing = slices[1].PixelSpacingprint spacing>>[.734375, .734375]
