newMriImageFromDicomDirectory: Functions for reading images from DICOM files

Description

Functions for reading images from a directory of DICOM files.

Usage

readDicomDirectory(dicomDir, readDiffusionParams = FALSE, untileMosaics = TRUE)
newMriImageFromDicomDirectory(dicomDir, readDiffusionParams = FALSE,
    untileMosaics = TRUE)

Arguments

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?

untileMosaics

Logical value: should Siemens mosaic images be converted into 3D volumes? This may occasionally be performed in error, which can be prevented by setting this value to FALSE.

Value

• 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.
