Hello all.
I will be obtaining on a regular basis ACR/NEMA-formatted MR images,
exported from a Philips Gyroscan MR system, and would like to know if
anyone has a utility to extract the raw images from these files.
I've already grabbed the DICOM 3.0 package, but its focus seems to be
more on client/server architecture and image display. I want to get at
the images themselves, not just display them. I have poked around the
source code a bit and see some places where I might be able to hack,
but if someone has already done this and is willing to share, I would
apprecitate not having to reinvent the wheel here.
Right now, I get GE Signa 5.x MR images, and simply skip the header
information (a constant size for the images I obtain) in each image
file to get to the raw data, convert that data to unsigned bytes
in the range [0-255], and write an MR *volume* file, the number of bytes
equal to the product of the x, y, and z (# of slices) dimensions, and
the size of unsigned bytes on my machine (in this case, 1). It appears
as thought I cannot apply the same strategy to ACR/NEMA formatted
images.
Thanks in advance,
Matthew
