Bases: object

check_definition(definition, values: dict) → bool

Checks whether the specified header information values satisfy the provided definition.

Parameters

• definition (dict or list) – The imaging sequence definition, as a dict or list of dict instances.

• values (dict) – Header information provided for the comparison.

Returns

Whether the given header information fits the definition.

Return type

bool

Raises

TypeError – Encountered a definition of an invalid type.

detect(modality: str, values: dict) → str

Tries to detect the imaging sequence according to the modality and provided header information.

Parameters

• modality (str) – The imaging modality as described in the DICOM header.

• values (dict) – Sequence identifying header elements.

Returns

The detected sequence name or None.

Return type

str

get_known_modality_sequences(modality: str) → dict

Returns a dictionary of imaging sequence definitions.

Parameters

modality (str) – The modality for which to return imaging sequence defitions.

Returns

Imaging sequence definitions.

Return type

dict

Raises

NotImplementedError – The sequences dictionary does not include the provided modality.
