dicomifier.dicom_to_nifti.stacks#

class dicomifier.dicom_to_nifti.stacks.OrientationGetter#

Return the ideal orientation of a data set, i.e. allow small variations in the actual orientation.

property orientations#
dicomifier.dicom_to_nifti.stacks.frame_group_index_getter(data_set, tag)#

Return bruker_to_dicom-specific frame group information.

dicomifier.dicom_to_nifti.stacks.ge_complex_image_component_getter(data_set, tag)#

Return GE-specific Complex Image Component data.

dicomifier.dicom_to_nifti.stacks.ge_diffusion_getter(data_set, tag)#

Return GE-specific diffusion data.

dicomifier.dicom_to_nifti.stacks.get_diffusion(data_set, tag)#

Get b-value and gradient diffusion from the data_set.

dicomifier.dicom_to_nifti.stacks.get_dimension_index(data_set, tag, in_stack_position_index)#

Return the dimension index pointer without InStackPosition in order to find the different volumes

Parameters:

in_stack_position_index – index of the In Stack Position element within the Dimension Index tuple

dicomifier.dicom_to_nifti.stacks.get_frame_position(data_set, frame_index)#

Get the position of the specified frame.

dicomifier.dicom_to_nifti.stacks.get_in_stack_position_index(data_set)#

Return the position of In Stack Position element inside the Dimension Index.

dicomifier.dicom_to_nifti.stacks.get_stacks(data_sets, extra_splitters=None)#

Return the stacks contained in the data sets. The result is a dictionary in which the values are pairs of (data_set, frame_index) (in the case of single-frame data sets, frame_index is None), and in which the keys are tuples of selectors. In this context, a selector is defined as a pair of (group sequence, group, tag) (group sequence and group being None for single-frame data sets), and a value.

Parameters:

  • data_sets – list of dicom data sets

  • extra_splitters – additional splitters to be used when building stacks

dicomifier.dicom_to_nifti.stacks.siemens_coil_getter(data_set, tag)#

Return Siemens-specific coil identifier.

dicomifier.dicom_to_nifti.stacks.sort(key, frames)#

Sort the frames of a stack according to the items present in the stack key.
