Localisation is assumed to be perfect in the z direction and determined by
the ker input in the x-y direction.
get_mrsi2d_seg(mrs_data, mri_seg, ker)
Arguments
- mrs_data
2D MRSI data with multiple voxels in the x-y dimension.
- mri_seg
MRI data with values corresponding to the segmentation class.
Must be 1mm isotropic resolution.
- ker
MRSI PSF kernel in the x-y direction compatible with the mmand
package, eg: mmand::shapeKernel(c(10, 10), type = "box").
Value
a data frame of partial volume estimates and individual segmentation
maps.
