Detailed Description

Projection data info for data for a scanner with discrete detectors.

This class also contains some functions specific for (static) full-ring PET scanners. In this case, it is assumed that for 'raw' data (i.e. no mashing) sinogram space is 'interleaved': 2 adjacent LOR_angles are merged to 1 'view', while the corresponding bins are interleaved:

   before interleaving               after interleaving
   a00     a01     a02 ...      view 0: a00 a10 a01 a11  ...
       a10     a11     ...
   a20     a21     a22 ...      view 1: a20 a30 a21 a31 ...
       a30     a31     ...

This (standard) interleaving is done because for 'odd' LOR_angles there is no LOR which goes through the origin.

Interchanging the 2 detectors

When the ring difference = 0 (i.e. a 2D - or direct - sinogram), interchanging the 2 detectors does not change the LOR. This is why (in 2D) one gets away with a full sinogram size of num_views * 2 * num_views, where the size of 'detector-space' is twice as large. However, in 3D, interchanging the detectors, also interchanges the rings. One has 2 options:

have 1 sinogram with twice as many views, together with the rings as 'unordered pair' (i.e. ring_difference is always >0)
have 2 sinograms of the same size as in 2D, together with the rings as 'ordered pair' (i.e. ring_difference can be positive and negative). In STIR, we use the second convention.

Member Function Documentation

◆ get_s()

float stir::ProjDataInfoGenericNoArcCorr::get_s ( const Bin & bin ) const

inlineoverridevirtual

Gets s coordinate in mm.

Warning: This does not take the 'interleaving' into account which is customarily applied to raw PET data.

warning In cylindrical s is found from bin: sin(beta) = sin(tang_pos*angular_increment) In block it is calculated directly from corresponding lor

Implements stir::ProjDataInfo.

◆ get_view_tangential_pos_num_for_det_num_pair()

bool stir::ProjDataInfoGenericNoArcCorr::get_view_tangential_pos_num_for_det_num_pair	(	int &	view_num,
		int &	tang_pos_num,
		const int	det1_num,
		const int	det2_num
	)		const

inline

This gets view_num and tang_pos_num for a particular detector pair.

This function makes only sense if the scanner is a full-ring scanner with discrete detectors and there is no rotation or wobble.

view runs currently from 0 to num_views-1

tang_pos_num is centred around 0, where 0 corresponds to opposing detectors. The maximum range of tangential positions for any scanner is -(num_detectors)/2<tang_pos_num<=-(num_detectors)/2+num_detectors, but this range is never used (as the 'last' tang_pos_num would be a LOR between two adjacent detectors).

det_num1, det_num2 run from 0 to num_detectors-1

Returns: true if the detector pair is stored in a positive segment, false otherwise.

Warning: Current implementation only checked for Siemens/CTI scanners. It assumes interleaved data.; Will call error() if certain conditions are not met.

		int &	det2_num,
		const int	view_num,
		const int	tang_pos_num
	)		const

inline

This routine gets det_num1 and det_num2.

It sets the detectors in a particular order (i.e. it fixes the orientation of the LOR) corresponding to the detector pair belonging to a positive segment.

Warning: This currently only works when no mashing of views is used, as otherwise there would be multiple detector pairs corresponding to a single bin.

See also: get_view_tangential_pos_num_for_det_num_pair() for info and restrictions.

Warning: Will call error() if certain conditions are not met.

Succeeded stir::ProjDataInfoGenericNoArcCorr::get_bin_for_det_pos_pair	(	Bin &	bin,
		const DetectionPositionPair<> &	dp
	)		const

inline

This gets Bin coordinates for a particular detector pair.

Note that when axial compression and/or mashing is applied, this is a many-to-one relation, i.e. multiple detector pairs contribute to one bin.

Returns: Succeeded::yes when a corresponding bin is found in the range of projection data. Currently, the Bin value is always set to 1.

This routine gets the detector pair corresponding to a bin.

See also: get_det_pair_for_view_tangential_pos_num() for restrictions. In addition, this routine only works for span=1 data, i.e. no axial compression.

Todo:: use member template for the coordT type to support continuous detectors.

void stir::ProjDataInfoGenericNoArcCorr::get_all_det_pos_pairs_for_bin	(	std::vector< DetectionPositionPair<>> &	dps,
		const Bin &	bin
	)		const

This routine fills a vector with all the detector pairs that correspond to a bin.

See also: ProjDataInfoCylindrical::get_all_ring_pairs_for_segment_axial_pos_num for restrictions.

Todo:: It might be possible to return some weight factors in case there is no many-to-one correspondence between detection positions and bins (for instance for continuous detectors, or rotating scanners, or arc-corrected data).

◆ get_bin()

Bin stir::ProjDataInfoGenericNoArcCorr::get_bin	(	const LOR< float > &	,

overridevirtual

Find the bin in the projection data that 'contains' an LOR.

Projection data corresponds to lines, so most Lines Of Response (LORs) there is a bin in the projection data. Usually this will be the bin which has a central LOR that is 'closest' to the LOR that is passed as an argument.

If there is no such bin (e.g. the LOR does not intersect the detectors, Bin::get_bin_value() will be less than 0, otherwise it will be 1.

Warning: This function might get a different type of arguments in the next release.
