Parse DICOM Data: Parse DICOM Pixel or Spectroscopy Data
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
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).
Value
- A list containing two elements:
[object Object],[object Object]
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.
