parseData: Parse DICOM Pixel or Spectroscopy Data

Description Usage Arguments Details Value Author(s) Source References See Also

Description

These subroutines process the information contained after the DICOM header and process this information into an image (2D or 3D) or complex-valued vector.

Usage

1
2
parsePixelData(rawString, hdr, endian = "little", flipupdown = TRUE)
parseSpectroscopyData(rawString, hdr, endian = "little")

Arguments

rawString

is a vector of raw values taken directly from the DICOM file.

hdr

is the list object of DICOM header information.

endian

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

flipupdown

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

Details

A while loop is used to traverse the unknown number of DICOM header fields contained in a single file. Information contained in “sequences” may be included/excluded according to the logical variable skipSequence (default = TRUE).

A resursive implementation of the code breaks the DICOM file into segments and calls itself to parse each segment.

Value

A list containing two elements:

hdr

all DICOM header fields (with or without “sequence” information).

img

the ‘image’ information.
