Constructor & Destructor Documentation

§ SeqAcqRead() [1/3]

SeqAcqRead::SeqAcqRead ( const STD_string &  object_label,
double  sweepwidth,
unsigned int  read_size,
float  fov,
direction  gradchannel,
float  os_factor = 1.0,
float  partial_fourier = 0.0,
bool  partial_fourier_at_end = false,
const STD_string &  nucleus = "",
const dvector phaselist = 0,
const dvector freqlist = 0,
float  timestep = 0.0,
rampType  rampmode = linear 

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

  • sweepwidth: The sampling frequency
  • read_size: The desired matrix size in read direction
  • fov: The Field of View
  • gradchannel: The channel where the read gradient will be placed
  • os_factor: See class 'SeqAcq' for explanation
  • partial_fourier: The amount of partial Fourier undersampling (0=no undersampling, 1=half fourier)
  • partial_fourier_at_end: If set to 'true', partial Fourier will omit data at the end of the readout
  • nucleus: See class 'SeqAcq' for explanation
  • phaselist: See class 'SeqAcq' for explanation
  • freqlist: See class 'SeqAcq' for explanation
  • timestep: The time resolution for the digitised ramps, the default is to take minimum time step the scanner is capable of.
  • rampmode: This parameter determines the shape of the ramp waveform

§ SeqAcqRead() [2/3]

SeqAcqRead::SeqAcqRead ( const SeqAcqRead sar)

Constructs an acquisition window with read gradient which is a copy of 'sar'

§ SeqAcqRead() [3/3]

SeqAcqRead::SeqAcqRead ( const STD_string &  object_label = "unnamedSeqAcqRead")

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

Member Function Documentation

§ get_acquisition_center()

double SeqAcqRead::get_acquisition_center ( ) const

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

Reimplemented from SeqAcqInterface.

§ get_acquisition_start()

double SeqAcqRead::get_acquisition_start ( ) const

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.

§ get_readgrad()

const SeqGradTrapez& SeqAcqRead::get_readgrad ( ) const

Returns reference to read gradient.

Definition at line 84 of file seqacqread.h.

§ operator=()

SeqAcqRead& SeqAcqRead::operator= ( const SeqAcqRead sar)

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

§ set_sweepwidth()

SeqAcqInterface& SeqAcqRead::set_sweepwidth ( double  sw,
float  os_factor 

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

Reimplemented from SeqAcqInterface.
