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.

Constructor & Destructor Documentation

§ SeqFieldMap()

SeqFieldMap::SeqFieldMap ( )
inline

Constructs a field-map scan

Member Function Documentation

§ build_seq()

void SeqFieldMap::build_seq ( double  sweepwidth,
float  os_factor = 1.0,
const SeqObjList prep = SeqObjList(),
double  min_relaxdelay = 0.0 
)

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

§ get_parblock()

LDRblock& SeqFieldMap::get_parblock ( )

Returns block of local parameters

§ init()

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.
