Functions for reading images from DICOM files

Description

Functions for reading images from DICOM files.

Usage

newMriImageFromDicom(fileName)
newMriImageFromDicomDirectory(dicomDir, readDiffusionParams = FALSE)
newMriImageFromDicomMetadata(metadata, flipY = TRUE)
newMriImageMetadataFromDicom(fileName)
newMriImageMetadataFromDicomMetadata(dicom)

Arguments

fileName Character vector of length one giving the name of a DICOM file.
dicomDir Character vector of length one giving the name of a directory containing DICOM files.
readDiffusionParams Logical value: should diffusion MRI parameters (b-values and gradient directions) be retrieved from the files if possible?
metadata, dicom DicomMetadata objects.
flipY Logical value: should the image be flipped in the Y direction? Usually this is appropriate to convert between DICOM's LPS and TractoR's LAS storage conventions.

Value

newMriImageFromDicom and newMriImageFromDicomMetadata return an MriImage object. newMriImageMetadataFromDicom and newMriImageMetadataFromDicomMetadata return an MriImageMetadata object. newMriImageFromDicomDirectory returns a list containing elements

image An MriImage object.
bValues Diffusion b-values, if requested. Will be NA if the information could not be found in the files.
bVectors Diffusion gradient vectors, if requested. Will be NA if the information could not be found in the files.
