Detailed Description

Multi-echo module for field-map pre-scan.

In order to acquire a field-map together with the actual scan, this sequence module employs an EPI-like readout where each shot acquires an even number of alternating echoes (each with a different TE) separately for each line in k-space.

Member Function Documentation

void SeqFieldMap::init

(

const STD_string &

objlabel

)

Initialize field-map scan with default values, sequence objects are prefixed by 'objlabel'. This function is usually called in the sequence initialization step.

void SeqFieldMap::build_seq	(	double	sweepwidth,
		const SeqObjList &	prep = SeqObjList(),
		double	min_relaxdelay = 0.0
	)

Builds the field-map scan using bandwidth 'sweepwidth', an extra preparation 'prep' prior to each excitation and minimum relaxation delay 'min_relaxdelay'. This function is usually called in the sequence building step.

JcampDxBlock& SeqFieldMap::get_parblock

(

)

Returns block of local parameters
