newMriImageFromDicom: 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.
