shivaPvsSegmentation: SHIVA PVS/VRS segmentation.

In ANTsX/ANTsRNet: Neural Networks for Medical Image Processing

SHIVA PVS/VRS segmentation.

Description

Perform segmentation of perivascular (PVS) or Vircho-Robin spaces (VRS). https://pubmed.ncbi.nlm.nih.gov/34262443/ with the original implementation available here: https://github.com/pboutinaud/SHIVA_PVS

Usage

shivaPvsSegmentation(
  t1,
  flair = NULL,
  whichModel = "all",
  doPreprocessing = TRUE,
  verbose = FALSE
)

Arguments

t1	input 3-D T1-weighted brain image.
flair	(Optional) input 3-D FLAIR brain image (aligned to T1 image).
whichModel	integer or string. Several models were trained for the case of T1-only or T1/FLAIR image pairs. One can use a specific single trained model or the average of the entire ensemble. I.e., options are: * For T1-only: 0, 1, 2, 3, 4, 5. * For T1/FLAIR: 0, 1, 2, 3, 4. * Or "all" for using the entire ensemble.
doPreprocessing	perform n4 bias correction, intensity truncation, brain extraction.
verbose	print progress.

Value

probabilistic image.
