I have a DICOM (CT IMage) and i need to extract the text information (HEADER).

I need to get each specific byte for it to work.

Can you help me, The relevant info is here http://www.psychology.nottingham.ac.uk/staff/cr1/dicom.html this will show you where the bytes are, and i can email you a dicom file if you require, but i believe therre are some downloadable ones there.

Just for sake i want in this demo to extract 0010,0010 (Patient Name)  ONLY, by clicking a button, for it to open the file, and get info.

PLEASE HELP.

Read the whole file

ie

    Dim ff As Integer, Filename As String, s As String
   
    Filename = "Yourfile"
    ff = FreeFile
    Open Filename For Binary Access Read Lock Read Write As #ff
    s = Space$(LOF(ff))
    Get #ff, , s
    Close ff

    dim Arr, I as long
    arr = split(s, vbcrlf)
    for i=0 to ubound(arr)
         if (instr(arr(i), "0010,0010") then
               ' Find the line extra data from here
              exit for
         endif
    next
    erase arr

This does not search through the file? IF i put un unknow file in, it does not give an error,

Could you put the result into a text field so that i can see what is has found?? and maybe put a limiter on it to say....

Display everything between 0010,0010 and 0011,0011 for example.

I WILL offer more pooints, i am waiting for some deleted question points to come my way.

Thanx

Have you investigated the numerous DICOM reader controls and librarys available for DICOM manipulation. I use LeadTools medical imaging suite for our applications....Its costly though $8k for the full suite (2 month free eval though).  Doing this by hand will be difficult unless you are positive regarding the modality of your images (Tomagraph,Intraoral-pano, etc....) otherwise byte position will be extremely variable.

You don't even has 0011,0011  in the file?

It is very difficult to work with DICOM files from scratch. Even if you succeed to extract some information from some specific file, this way may fail on another file.
When you will get some result, try it on variuos files from here:
http://www.barre.nom.fr/medical/samples/

See also list of DICOM programs on this page. Usually they are developed in C or C++ and not VB.
For full solution I suggest you to use some third-party tool, which supports COM interface and available for VB developer. This is one of the best (and costs a lot of money,unfortualtely):
