Constructor & Destructor Documentation
◆ SeqGradSpiral() [1/3]
| SeqGradSpiral::SeqGradSpiral | ( | const STD_string & | object_label, |
| LDRtrajectory & | traj, | ||
| double | dt, | ||
| float | resolution, | ||
| unsigned int | sizeRadial, | ||
| unsigned int | numofSegments, | ||
| bool | inwards = false, |
||
| bool | optimize = false, |
||
| const STD_string & | nucleus = "" |
||
| ) |
Constructs a spiral gradient labeled 'object_label' and the following properties:
- traj: The spiral trajectory (will be modified, if neccessary)
- dt: The dwell time
- resolution: Spatial resolution
- sizeRadial: The number of image points in radial direction
- numofSegments : The number of spiral interleaves
- inwards: Reverse trajectory so that the spiral ends in the center of k-space, in addition, rotates trajectory by 180 deg
- optimize: Optimize trajectory for minimum readout length if trajectory has a free tunable parameter
- nucleus: The imaging nucleus
◆ SeqGradSpiral() [2/3]
| SeqGradSpiral::SeqGradSpiral | ( | const STD_string & | object_label = "unnamedSeqGradSpiral" | ) |
Constructs an empty spiral gradient with the given label.
◆ SeqGradSpiral() [3/3]
| SeqGradSpiral::SeqGradSpiral | ( | const SeqGradSpiral & | sgs | ) |
Constructs a spiral gradient which is a copy of 'sgs'
Member Function Documentation
◆ get_denscomp()
|
inline |
Returns the Jacobian determinante, i.e. the correction function for non-uniform weighting of k-space
Definition at line 91 of file seqgradspiral.h.
◆ get_ktraj()
Returns the k-space trajectory for the interleave 'iseg' and the given channel
◆ get_ramp_duration()
|
inline |
Returns the duration of the ramp that switches the gradients off
Definition at line 79 of file seqgradspiral.h.
◆ operator=()
| SeqGradSpiral& SeqGradSpiral::operator= | ( | const SeqGradSpiral & | sgs | ) |
This assignment operator will make this object become an exact copy of 'sgs'.
◆ set_predelay_duration()
| SeqGradSpiral& SeqGradSpiral::set_predelay_duration | ( | double | dur | ) |
Sets the delay of the gradient delays preceding the spiral gradients
◆ spiral_size()
|
inline |
Returns the size of the spiral without ramps
