pydicom.pixel_data_handlers.gdcm_handler

Use the GDCM Python package to decode pixel transfer syntaxes.

Functions

create_data_element(dicom_dataset)	Return a gdcm.DataElement for the Pixel Data.
create_image(dicom_dataset, data_element)	Return a gdcm.Image.
create_image_reader(filename)	Return a gdcm.ImageReader.
get_pixeldata(dicom_dataset)	Use the GDCM package to decode Pixel Data.
is_available()	Return True if the handler has its dependencies met.
needs_to_convert_to_RGB(dicom_dataset)	Return True if the Pixel Data should to be converted from YCbCr to RGB.
should_change_PhotometricInterpretation_to_RGB(…)	Return True if the Photometric Interpretation should be changed to RGB.
supports_transfer_syntax(transfer_syntax)	Return True if the handler supports the transfer_syntax.

pydicom.pixel_data_handlers.gdcm_handler.create_data_element(dicom_dataset)

Return a gdcm.DataElement for the Pixel Data.

Parameters

dicom_dataset (dataset.Dataset) – The Dataset containing the Pixel Data.

Returns

The converted Pixel Data element.

Return type

gdcm.DataElement

pydicom.pixel_data_handlers.gdcm_handler.create_image(dicom_dataset, data_element)

Return a gdcm.Image.

Parameters

• dicom_dataset (dataset.Dataset) – The Dataset containing the Image Pixel module.

• data_element (gdcm.DataElement) – The gdcm.DataElement Pixel Data element.

Returns

Return type

gdcm.Image

pydicom.pixel_data_handlers.gdcm_handler.create_image_reader(filename)

Return a gdcm.ImageReader.

Parameters

filename (str or unicode) – The path to the DICOM dataset.

Returns

Return type

gdcm.ImageReader

pydicom.pixel_data_handlers.gdcm_handler.get_pixeldata(dicom_dataset)

Use the GDCM package to decode Pixel Data.

Returns

A correctly sized (but not shaped) array of the entire data volume

Return type

numpy.ndarray

Raises

• ImportError – If the required packages are not available.

• TypeError – If the image could not be read by GDCM or if the Pixel Data type is unsupported.

• AttributeError – If the decoded amount of data does not match the expected amount.

pydicom.pixel_data_handlers.gdcm_handler.is_available()

Return True if the handler has its dependencies met.

pydicom.pixel_data_handlers.gdcm_handler.needs_to_convert_to_RGB(dicom_dataset)

Return True if the Pixel Data should to be converted from YCbCr to RGB.

This affects JPEG transfer syntaxes.

pydicom.pixel_data_handlers.gdcm_handler.should_change_PhotometricInterpretation_to_RGB(dicom_dataset)

Return True if the Photometric Interpretation should be changed to RGB.

This affects JPEG transfer syntaxes.

pydicom.pixel_data_handlers.gdcm_handler.supports_transfer_syntax(transfer_syntax)

Return True if the handler supports the transfer_syntax.

Parameters

transfer_syntax (uid.UID) – The Transfer Syntax UID of the Pixel Data that is to be used with the handler.
