All information, both header and image, is read into a list structure from a DICOM file.

Usage

dicomInfo(fname, endian = "little", flipud = TRUE, skip128 = TRUE,
          DICM = TRUE, skipSequence = TRUE, pixelData = TRUE,
          warn = -1, debug = FALSE)

Arguments

fname

is the file name of the DICOM image (with suffix).

endian

is the endian-ness of the file (default is "little").

flipud

is a logical variable for vertical flipping of the image (default is TRUE).

skip128

is a logical variable to skip the first 128 bytes in the file (default = TRUE).

DICM

is a logical variable to read in the four bytes "DICM" (default = TRUE).

skipSequence

is a logical variable to skip all content contained in SequenceItem tags (default = TRUE).

pixelData

is a logical variable (default = TRUE) on whether or not the PixelData should be read from the DICOM files.

warn

is a number to regulate the display of warnings (default = -1). See options for more details.
