I have a directory that is filled with DICOM files that I obtained by using the
Offis DICOM tool kit.
The dictionary file I have is not included in the DICOM file. I have a flat
file that has all of the DICOM fields defined as a python dictionary. In my
initial post I
included only the first section.
dicomdict = {
# meta tags

Correct I have no idea how to use the dictionaries to help me complete my task.
Currently I have the following
#!/usr/bin/python
##
import os,linecache # import the os and linecache module
import string
# First thing is to look at a directory and list
# out its contents.
# open a config file to determine the directory, only use a
# specific line in this case line #7.
dir = linecache.getline('./config',7)
# os.listdir(pathname) will list the pathname.
files = os.listdir(dir[:-1]) # remove the \n from the end of dir.
for file in files:
dfile = dir[:-1]+file
print dfile
dicom_file = open(dfile, "rb")
elem = dicom_file.readlines()
print elem
dicom_file.close() # close DICOM Files
I can open each DICOM file but it reads everything from beginning to end which
is not very efficient. I only want to pop out the elements that I am
interested in.
Hope this makes a little more sense.
