orthogonal-planes {oro.dicom}

Orthogonal Planes

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
