Constructs an acquisition window with a simultaneous spiral gradient labeled 'object_label' and the following properties:
- sweepwidth: The sampling frequency
- fov: The Field of View in radial direction
- sizeRadial: The number of image points in radial direction
- numofSegments : The number of spiral interleaves
- traj: The spiral trajectory (will be modified, if neccessary)
- inout: Spiral-in spiral-out trajectory
- optimize: Optimize trajectory for minimum readout length if trajectory has a free tunable parameter
- nucleus: See class 'SeqAcq' for explanation
- phaselist: See class 'SeqAcq' for explanation
| SeqAcqSpiral::SeqAcqSpiral | ( | const SeqAcqSpiral & | sas | ) |
Constructs an acquisition window with spiral gradient which is a copy of 'sas'
| SeqAcqSpiral::SeqAcqSpiral | ( | const STD_string & | object_label = "unnamedSeqAcqSpiral" |
) |
Constructs an empty acquisition window with spiral gradient with the given label.
Member Function Documentation
| SeqAcqSpiral& SeqAcqSpiral::operator= | ( | const SeqAcqSpiral & | sas | ) |
This assignment operator will make this object become an exact copy of 'sar'.
| const SeqVector& SeqAcqSpiral::get_segment_vector | ( | ) | const [inline] |
Returns the vector of the spiral interleaves (for loop insertion)
Definition at line 84 of file seqacqspiral.h.
Returns the k-space trajectory for the interleave 'iseg'
| fvector SeqAcqSpiral::get_denscomp | ( | ) | const |
Returns the Jacobian determinante, i.e. the correction function for non-uniform weighting of k-space
| double SeqAcqSpiral::get_acquisition_center | ( | ) | const [inline, virtual] |
Returns the the duration from the the beginnig of the acquisition object to the middle of the acquisition window.
Reimplemented from SeqAcqInterface.
Definition at line 100 of file seqacqspiral.h.
| double SeqAcqSpiral::get_acquisition_start | ( | ) | const [inline, 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.
Definition at line 101 of file seqacqspiral.h.
| SeqAcqInterface& SeqAcqSpiral::set_sweepwidth | ( | double | sw, | |
| float | os_factor | |||
| ) | [virtual] |
Sets the sweepwidth 'sw' without oversampling and oversampling factor 'os_factor' for this acquisition object, os_factor=1 means no oversampling.
Reimplemented from SeqAcqInterface.
