MRIaggr-class: Class "MRIaggr"

In bozenne/MRIaggr: Management, Display, and Processing of Medical Imaging Data

Description

Patient-specific storage of multivariate contrast data and clinical data.

Arguments

identifier	the patient identifier. character.
contrast	the value of the contrast parameters for each observation. data.frame.
clinic	the clinical data of the patient. data.frame.
fieldDim	the dimensions of the spatial field (expressed in number of voxels) containing the voxels. data.frame.
voxelDim	the voxel size dimensions its unit of measure. A four columns data.frame with names "i", "j", "k" and "unit".
default_value	a reference value for each contrast parameter. data.frame.
history	a list of the calc or const methods that have been applied to the MRIaggr object . data.frame.
normalization	the normalization values of each contrast parameter. list.
hemispheres	the presence or absence of lesion(s) in each hemisphere. data.frame.
midplane	the position of the mid-sagittal plane. data.frame.
W	the neighbourhood matrix. list.
table_lesion	the vertical distribution of the lesion volumes. data.frame.
table_reperfusion	the volumic reperfusion data. data.frame.
table_hypoperfusion	the volumic hypoperfusion data. data.frame.
ls_statDesc	a slot to store additional data. list.
