Detailed Description

ODIN sequence modelling framework (odinseq library)

Enumeration Type Documentation

§ dephaseMode

This enum is used to specify the type of the pre-dephasing or post-rephasing gradient:

  • FID: It will have opposite polarity
  • spinEcho: It will have the same polarity
  • rephase: Gradient pulse to rephase acquisition gradients

Definition at line 40 of file seqacqdeph.h.

§ encodingScheme

This enum can be used to determine the encoding scheme of a list of values:

  • linearEncoding : values are played out in the same order as specified
  • reverseEncoding : values are played out in the reverse order as specified
  • centerOutEncoding : encoding start in the center of values and moves outwards alternatingly in positive/negative direction
  • centerInEncoding : encoding starts outwards and moves inwards alternatingly in positive/negative direction
  • maxDistEncoding : Maximum distance between consecutive elements

Definition at line 37 of file seqvec.h.

§ pulseType

enum pulseType

Enum to specify the type of a pulse.It is essential for the calculation of k-space trajectories and other stuff to specify this correctly for each object derived from 'SeqPulsInterface'

  • excitation: An excitation pulse.
  • refocusing: A refocusing pulse.
  • storeMagn: Stores the magnetization in longitudinal direction (stimulated echo)
  • recallMagn: Recalls the magnetization from the longitudinal direction (stimulated echo)
  • inversion: An inversion pulse
  • saturation: A saturation pulse

Definition at line 42 of file seqpuls.h.

§ rampType

enum rampType

This enum is used to specify the shape of gradient ramp:

  • linear: A ramp that linearly increases/decreases the gradient field. The first ramp point has the initial gradient strength, the last point the final gradient strength. With this selection, the integral over the ramp is the same as that over a continuous triangular function, i.e Integral = 1/2 * strength_difference * duration.
  • sinusoidal: The sinus between -pi/2 and pi/2 is used for the gradient shape
  • half_sinusoidal: The sinus between 0 and pi/2 is used for the gradient shape

Definition at line 42 of file seqgradramp.h.

§ reorderScheme

This enum can be used to determine the reordering scheme of a list of values:

  • noReorder : No reordering is performed, the number of reorderings is then equal one
  • rotateReorder : The values will be rotated, the number of reorderings is then the number of values
  • blockedSegmented : The values will be divided into segments, preserving their order
  • interleavedSegmented : The values will be divided into segments like distributing game cards

Definition at line 48 of file seqvec.h.

§ satNucleus

enum satNucleus

Enum to specifiy saturation component:

  • fat: lipid protons will be saturated
  • water: water protons will be saturated

Definition at line 37 of file seqsat.h.
