Construct a ProjDataInfo with span=3 for segment 0, but span=1 for others.

This function implements our old understanding of GE data. An alternative is to use construct_proj_data_info() with span=2.

static

Construct a ProjDataInfo suitable with a given span.

span is used to denote the amount of axial compression (see the STIR glossary). Higher span, more axial compression. Span 1 means no axial compression. Siemens/CTI currently uses odd span. GE scanners use a mixed case where segment 0 has span 3, while other segments have span 2. We call this span 2. As a generalisation, this function supports any even span.

◆ get_bin()

		const double	delta_time = `0.0`
	)		const

pure virtual

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.

Get empty related viewgrams, where the symmetries_ptr specifies the symmetries to use.

make_num_tangential_poss_odd has to be false

◆ set_bed_position_horizontal()

void stir::ProjDataInfo::set_bed_position_horizontal ( const float bed_position_horizontal_arg )

inline

Vector which holds the lower and higher boundary for each TOF position, without the application of TOF mashing, in mm, for faster access.

Set horizontal bed position

Default implementation checks common variables. Needs to be overloaded.

Implemented in stir::ProjDataInfoCylindrical, stir::ProjDataInfoGenericNoArcCorr, and stir::ProjDataInfoSubsetByView.
