Constructor & Destructor Documentation

SeqAcqRead::SeqAcqRead	(	const STD_string &	object_label,
		double	acqduration,
		unsigned int	nAcqPoints,
		channelNo	gradchannel,
		float	gradstrength,
		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:

• acqduration: See class 'SeqAcq' for explanation
• nAcqPoints: The number of samples
• gradchannel: The channel where the read gradient will be placed
• gradstrength: The strength of the read gradient during acquisition
• 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::SeqAcqRead	(	const STD_string &	object_label,
		double	sweepwidth,
		unsigned int	nAcqPoints,
		float	fov,
		channelNo	gradchannel,
		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
• nAcqPoints: The number of samples
• fov: The Field of View
• gradchannel: The channel where the read gradient will be placed
• 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::SeqAcqRead

(

const SeqAcqRead &

sar

)

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

SeqAcqRead::SeqAcqRead

(

const STD_string &

object_label = "unnamedSeqAcqRead"

)

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

Member Function Documentation

SeqAcqRead& SeqAcqRead::operator=

(

const SeqAcqRead &

sar

)

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

const SeqGradTrapez& SeqAcqRead::get_readgrad

(

)

const [inline]

Returns reference to read gradient.

Definition at line 100 of file seqacqread.h.

double SeqAcqRead::get_acquisition_center

(

)

const [virtual]

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

Reimplemented from SeqAcqInterface.

double SeqAcqRead::get_acquisition_start

(

)

const [virtual]

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.

const SeqVector* SeqAcqRead::get_dephgrad	(	SeqGradChanParallel &	dephobj,
		bool	rephase
	)			const [virtual]

to be used by SeqAcqDeph to retrieve pre-dephasing gradients from acquisition object. Overload this function if your acq needs pre-dephasers, return them by appending them to 'dephobj'. Returns any possible vector object as the return value.

Reimplemented from SeqAcqInterface.
