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, | |
| 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.
| JcampDxBlock& SeqFieldMap::get_parblock | ( | ) |
Returns block of local parameters
