Settings

Positive Shift X Boolean

Sets the direction of the x-gradient in relation to the image matrix

Positive Shift Y Boolean

Sets the direction of the y-gradient in relation to the image matrix

Positive Shift Z Boolean

Sets the direction of the z-gradient in relation to the image matrix

Bandwidth X (Hz/Voxel) Number

The applied bandwidth (frequency encoding) in the X-direction given in Hz/Voxel

Bandwidth Y (Hz/Voxel) Number

The applied bandwidth (frequency encoding) in the Y-direction given in Hz/Voxel

Bandwidth Z (Hz/Voxel) Number

The applied bandwidth (read out) in the Z-direction given in Hz/Voxel

Gyromagnetic Ratio (Hz/T) Number

The gyromagnetic ratio to use. Typically this is the default value of 42.57e+6 Hz/T
