Non-image DICOM objects
DICOM Image objects have pixel data and are store as NumPy.ndarray. However, non-image objects (e.g. structured reports) has typically no pixel data associated. Such objects can be read using Series(), Study(), etc. The resulting Series object will have an empty pixel array. The DICOM Datasets will be present in the header.datasets list.
Imagedata will not interpret the datasets. They are stored and available for application program to use.
