Detailed Description

Acquisition + spiral gradient.

This class contains a gradient with a spiral k-space trajectory together with an acquisition window

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.
