Constructor & Destructor Documentation

◆ SeqAcqSpiral() [1/3]

SeqAcqSpiral::SeqAcqSpiral	(	const STD_string &	object_label,
		double	sweepwidth,
		float	fov,
		unsigned int	sizeRadial,
		unsigned int	numofSegments,
		LDRtrajectory &	traj,
		bool	inout = `false`,
		bool	optimize = `false`,
		const STD_string &	nucleus = `""`,
		const dvector &	phaselist = `0`
	)

Constructs an acquisition window with a simultaneous spiral gradient labeled 'object_label' and the following properties:

sweepwidth: The sampling frequency
fov: The Field of View in radial direction
sizeRadial: The number of image points in radial direction
numofSegments : The number of spiral interleaves
traj: The spiral trajectory (will be modified, if neccessary)
inout: Spiral-in spiral-out trajectory
optimize: Optimize trajectory for minimum readout length if trajectory has a free tunable parameter
nucleus: See class 'SeqAcq' for explanation
phaselist: See class 'SeqAcq' for explanation

◆ SeqAcqSpiral() [2/3]

SeqAcqSpiral::SeqAcqSpiral ( const SeqAcqSpiral & sas )

Constructs an acquisition window with spiral gradient which is a copy of 'sas'

◆ SeqAcqSpiral() [3/3]

SeqAcqSpiral::SeqAcqSpiral ( const STD_string & object_label = "unnamedSeqAcqSpiral" )

Constructs an empty acquisition window with spiral gradient with the given label.

Member Function Documentation

◆ get_acquisition_center()

double SeqAcqSpiral::get_acquisition_center ( ) const

inlinevirtual

Returns the the duration from the the beginnig of the acquisition object to the middle of the acquisition window.

Reimplemented from SeqAcqInterface.

Definition at line 101 of file seqacqspiral.h.

◆ get_acquisition_start()

double SeqAcqSpiral::get_acquisition_start ( ) const

inlinevirtual

Returns the the duration from the the beginnig of the acquisition object to the beginnig of the acquisition window (the point of time where data starts to be acquired).

Reimplemented from SeqAcqInterface.

Definition at line 102 of file seqacqspiral.h.

◆ get_denscomp()

fvector SeqAcqSpiral::get_denscomp ( ) const

Returns the Jacobian determinante, i.e. the correction function for non-uniform weighting of k-space

◆ get_ktraj()

fvector SeqAcqSpiral::get_ktraj	(	unsigned int	iseg,
		direction	channel
	)		const

Returns the k-space trajectory for the interleave 'iseg'

◆ get_segment_vector()

const SeqVector& SeqAcqSpiral::get_segment_vector ( ) const

inline

Returns the vector of the spiral interleaves (for loop insertion)

Definition at line 85 of file seqacqspiral.h.

◆ operator=()

SeqAcqSpiral& SeqAcqSpiral::operator= ( const SeqAcqSpiral & sas )

This assignment operator will make this object become an exact copy of 'sar'.

◆ set_sweepwidth()

SeqAcqInterface& SeqAcqSpiral::set_sweepwidth	(	double	sw,
		float	os_factor
	)

virtual

Sets the sweepwidth 'sw' without oversampling and oversampling factor 'os_factor' for this acquisition object, os_factor=1 means no oversampling.

Reimplemented from SeqAcqInterface.
