python 读取DICOM头文件的实例

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(H:\Data\data\\21662\\2.16.840.1.113662.2.0.105002416.1489146183.701\CT\\CT#0#21662#E7AB693D.dcm) print ds >> (0008, 0008) Image Type CS: [ORIGINAL, SECONDARY, AXIAL] (0008, 0016) SOP Class UID UI: CT Image Storage (0008, 0018) SOP Instance UID UI: 2.16.840.1.113662.2.0.105002416.1489146183.501.0 (0008, 0020) Study Date DA: 20170310 (0008, 0021) Series Date DA: 20170310 (0008, 0023) Content Date DA: 20060505 (0008, 0030) Study Time TM: 1942 (0008, 0031) Series Time TM: 1942 (0008, 0033) Content Time TM: (0008, 0050) Accession Number SH: 63071 (0008, 0060) Modality CS: CT (0008, 0070) Manufacturer LO: NOMOS (0008, 0090) Referring Physicians Name PN: (0008, 1010) Station Name SH: (0008, 1090) Manufacturers Model Name LO: CORVUS 6.4 (0010, 0010) Patients Name PN: *M32-2^CHENJUN^^^ (0010, 0020) Patient ID LO: 21662 (0010, 0030) Patients Birth Date DA: (0010, 0040) Patients Sex CS: (0018, 0050) Slice Thickness DS: 4.75 (0018, 0060) KVP DS: 0 (0018, 1020) Software Version(s) LO: CORVUS 6.4 (0018, 5100) Patient Position CS: HFS (0020, 000d) Study Instance UID UI: 2.16.840.1.113662.2.0.105002416.1489146183.701 (0020, 000e) Series Instance UID UI: 2.16.840.1.113662.2.0.105002416.1489146183.501 (0020, 0010) Study ID SH: 63071 (0020, 0011) Series Number IS: 0 (0020, 0012) Acquisition Number IS: 0 (0020, 0013) Instance Number IS: 0 (0020, 0020) Patient Orientation CS: [L, P] (0020, 0032) Image Position (Patient) DS: [0.73437356948853, 0, 3.25] (0020, 0037) Image Orientation (Patient) DS: [1, 0, 0, 0, 1, 0] (0020, 0052) Frame of Reference UID UI: 2.16.840.1.113662.2.0.105002416.1489146183.601 (0020, 0060) Laterality CS: (0020, 1040) Position Reference Indicator LO: (0020, 1041) Slice Location DS: 3.25 (0028, 0002) Samples per Pixel US: 1 (0028, 0004) Photometric Interpretation CS: MONOCHROME2 (0028, 0010) Rows US: 330 (0028, 0011) Columns US: 339 (0028, 0030) Pixel Spacing DS: [0.734375, 0.734375] (0028, 0100) Bits Allocated US: 16 (0028, 0101) Bits Stored US: 12 (0028, 0102) High Bit US: 11 (0028, 0103) Pixel Representation US: 0 (0028, 1052) Rescale Intercept DS: -1024 (0028, 1053) Rescale Slope DS: 1 (7fe0, 0010) Pixel Data

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]
