INTRODUCTION

The DICOM "Basic Worklist Management - Modality Worklist Management SOP Class" allows

modalities to query and retrieve worklist information from hospital information systems offering a

DICOM Modality Worklist SCP interface.

so that vendors participating in the demonstration only require a web browser on their systems.

PREREQUISITES

1. Web Browser

The Web Server component utilizes the HTML3 <TABLE> tags. Therefore, the web browser used

should support either HTML3 or HTML2 with Netscape extensions. We recommend Netscape 2.01

(any platform).

2. Web Server

The CGI scripts have been developed for the NCSA HTTPd 1.5 web server. However, any web

server supporting the same CGI interface should work. NCSA HTTPd 1.5 is available on many ftp

sites, including:

We recommend to install the perl binary as /usr/local/bin/perl.

INSTALLATION

Compilation of the WWW Server component is performed together with the DICOM component - see

installation instructions for the dcmtk source code. However, it is not possible to "automatically" install

the WWW server component with "make install".

1. ACCESS RIGHTS

A WWW server usually runs under a seperate user ID (e.g. user "www"). You must make sure that

both wlmscpfs and the WWW server are able to read and write to files in the worklist storage

areas. We recommend to have both WWW server and wlmscpfs running under the same user ID.

2. CREATE DIRECTORIES

data directory. Refer to the WWW server documentation for details.

c) a directory for the storage areas. This can be an arbitrary directory, e.g. /home/www/wlist.

Please remember that both wlmscpfs and the WWW server need read/write access to this

directory and all files and subdirectories (e.g. if WWW server and wlmscpfs work under

different user IDs, check if the umasks are appropriate to ensure read/write access for newly

created files).

3. INSTALL FILES

a) Copy all files from dcmtk/dcmwlm/perl to the CGI script directory you have created (e.g.

~www/cgi-bin/worklist). All files with file name extension ".pl" must have access right

"755" (executable). If your perl interpreter is not installed as /usr/local/bin/perl, you

4. CONFIGURE PERL SCRIPTS

You have to edit the file "prefs.ph" in the CGI directory (e.g. ~www/cgi-bin/worklist), using a text

editor:

a) Define the relative path to the CGI script directory as it is seen from the WWW server when

resolving URLs (e.g. /cgi-bin/worklist instead of ~www/cgi-bin/worklist). Refer to

your WWW server documentation for details of URL resolution. The configuration line will look

like this:

$prefs{'cgi_path'} = '/cgi-bin/worklist';
