InterMedia Dicom Support

Question

Hi!
I'm new in using Oracle and Oracle intermedia.
I' working on a project in which I have to read the metadata from a DICOM file and display the embedded images in a web browser.
I read the information from the user guide and try to implement, but I'm getting only errors and no results. Can anybody post some sample code for creating a table, importing Dicom files, extracting metadata and images?
Thank you,
Maria

Hi,
I used the presentation that you recommended and here is the code:
CREATE TABLE MEDICALIMAGES
(     ID NUMBER NOT NULL PRIMARY KEY,
     DESCRIPTION VARCHAR2(40 BYTE),
     METADATA XMLTYPE ,
     IMAGE ORDSYS.ORDIMAGE ,
     THUMB ORDSYS.ORDIMAGE ,
     IMAGE_J ORDSYS.ORDIMAGE
create or replace
procedure image_import_dicom
(dest_id number, filename varchar2, description varchar2) as
img ordsys.ordimage;
img1 ordsys.ordimage;
img2 ordsys.ordimage;
dicom_meta sys.xmltype;
ctx raw(64) := null;
begin
insert into medicalimages
values (dest_id, description,null,ordsys.ORDIMAGE.init(),ordsys.ordimage.init(),ordsys.ordimage.init());
select image into img from medicalImages where id=dest_id for update;
img.importFrom(ctx, 'file', 'IMAGEDIR', filename);
update medicalImages set image=img where id=dest_id;
dicom_meta :=img.getDicomMetadata('imageGeneral');
if (dicom_meta is not null) then
update medicalImages set metadata=dicom_meta where id =dest_id;
select image_j, thumb into img1, img2 from medicalImages where id=dest_id for update;
img.processcopy('fileformat=jfif', img1);
img1.processcopy('maxScale=80, 80', img2);
update medicalImages set image_j = img1, thumb=img2 where id=dest_id;
end if;
end;
I called the procedure with 2 files: “dummy.dcm” found in "Oracle interMedia Image Quick Start" and “brain.dcm” a dicom file found on the web, which is a valid Dicom file (I opened it with a viewer).
call image_import_dicom(2, 'brain.dcm', 'brain.dcm');
call image_import_dicom(3, 'dummy.dcm', 'dummy.dcm');
Every time I get the error:
Error report:
