Member Function Documentation

◆ get_related_bins()

void stir::TrivialDataSymmetriesForBins::get_related_bins	(	std::vector< Bin > &	rel_b,
		const Bin &	b,
		const int	min_axial_pos_num,
		const int	max_axial_pos_num,
		const int	min_tangential_pos_num,
		const int	max_tangential_pos_num,
		const int	min_timing_pos_num,
		const int	max_timing_pos_num
	)		const

overridevirtual

fills in a vector with all the bins (within the range) that are related to 'b'

Warning: b has to be a 'basic' bin

default implementation in terms of get_related_bins_factorised

Reimplemented from stir::DataSymmetriesForBins.

References stir::Bin::axial_pos_num(), stir::Bin::tangential_pos_num(), and stir::SegmentIndices::timing_pos_num().

◆ get_related_bins_factorised()

void stir::TrivialDataSymmetriesForBins::get_related_bins_factorised	(	std::vector< AxTangPosNumbers > &	,
		const Bin &	b,
		const int	min_axial_pos_num,
		const int	max_axial_pos_num,
		const int	min_tangential_pos_num,
		const int	max_tangential_pos_num
	)		const

overridevirtual

fills in a vector with the axial and tangential position numbers related to this bin

It is guaranteed (or at least, it should be by the implementation of the derived class) that these AxTangPosNumbers are related for all related ViewSegmentNumbers for this bin.

So, you can find all related bins by calling get_related_ViewSegmentNumbers() and get_related_bins_factorised(), which is what the default implementation does. (A derived class might do this in a more optimal way.)

Warning: b has to be a 'basic' bin

Implements stir::DataSymmetriesForBins.

References stir::Bin::axial_pos_num(), and stir::Bin::tangential_pos_num().

◆ num_related_bins()

int stir::TrivialDataSymmetriesForBins::num_related_bins ( const Bin & b ) const

overridevirtual

returns the number of bins related to 'b'

default implementation in terms of get_related_bins, will be slow of course

Reimplemented from stir::DataSymmetriesForBins.

◆ find_symmetry_operation_from_basic_bin()

unique_ptr< SymmetryOperation > stir::TrivialDataSymmetriesForBins::find_symmetry_operation_from_basic_bin ( Bin & ) const

overridevirtual

given an arbitrary bin 'b', find the basic bin and the corresponding symmetry operation

sets 'b' to the corresponding 'basic' bin and returns the symmetry transformation from 'basic' to 'b'.

Implements stir::DataSymmetriesForBins.

◆ find_basic_bin()

bool stir::TrivialDataSymmetriesForBins::find_basic_bin ( Bin & b ) const

overridevirtual

given an arbitrary bin 'b', find the basic bin

sets 'b' to the corresponding 'basic' bin and returns true if 'b' is changed (i.e. it was NOT a basic bin).

default implementation in terms of find_symmetry_operation_from_basic_bin

Reimplemented from stir::DataSymmetriesForBins.

◆ is_basic()

bool stir::TrivialDataSymmetriesForBins::is_basic ( const Bin & v_s ) const

overridevirtual

test if a bin is 'basic'

The default implementation uses find_basic_bin

Reimplemented from stir::DataSymmetriesForBins.

◆ num_related_view_segment_numbers()

int stir::TrivialDataSymmetriesForBins::num_related_view_segment_numbers ( const ViewSegmentNumbers & v_s ) const

overridevirtual

returns the number of view_segment_numbers related to 'v_s'

The default implementation is in terms of get_related_view_segment_numbers, which will be slow of course

Reimplemented from stir::DataSymmetriesForViewSegmentNumbers.

◆ find_basic_view_segment_numbers()

bool stir::TrivialDataSymmetriesForBins::find_basic_view_segment_numbers ( ViewSegmentNumbers & v_s ) const

overridevirtual

given an arbitrary view/segment, find the basic view/segment

sets 'v_s' to the corresponding 'basic' view/segment and returns true if 'v_s' is changed (i.e. it was NOT a basic view/segment).

Implements stir::DataSymmetriesForViewSegmentNumbers.
