Example Datasets (pydicom.examples)

The examples module contains the following DICOM datasets:

Module Attribute	File	SOP Class
ct	CT_small.dcm	CT Image
mr	MR_small.dcm	MR Image
rt_plan	rtplan.dcm	RT Plan
rt_dose	rtdose.dcm	RT Dose
rt_ss	rtstruct.dcm	RT Structure Set
overlay	MR-SIEMENS-DICOM-WithOverlays.dcm	MR Image
waveform	waveform_ecg.dcm	12 Lead ECG
rgb_color	US1_UNCR.dcm	US Image
palette_color	OBXXXX1A.dcm	US Image
jpeg2k	US1_J2KR.dcm	US Image
dicomdir	DICOMDIR	Media Storage

Usage

The module attributes are all normal FileDataset instances:

>>> from pydicom import examples
>>> type(examples.ct)
<class 'pydicom.dataset.FileDataset'>
>>> examples.ct.PatientName
'CompressedSamples^CT1'

Each time the module attribute is accessed a new FileDataset instance of the dataset will be returned:

>>> examples.ct is examples.ct
False
>>> examples.ct == examples.ct
True

Because of this, best practice is to assign the returned dataset to a local variable:

>>> ds = examples.ct
