is.axial: Orthogonal Planes

In oro.dicom: Rigorous - DICOM Input / Output

Description

Functions to test the orientation for a single slice.

Usage

is.axial(imageOrientationPatient, axial = c("L", "R", "A", "P"))

is.coronal(imageOrientationPatient, coronal = c("L", "R", "H", "F"))

is.sagittal(imageOrientationPatient, sagittal = c("A", "P", "H", "F"))

Arguments

imageOrientationPatient	A vector of length six taken from the DICOM header field “ImageOrientationPatient”.
axial	Characters that are valid in defining an ‘axial’ slice.
coronal	Characters that are valid in defining a ‘coronal’ slice.
sagittal	Characters that are valid in defining a ‘sagittal’ slice.

Value
