-- DICOM Web Viewer (DWV) lua script for integration in a Conquest PACS server.
|
|
--
|
|
-- Usage:
|
|
-- 1. copy this file onto your web server
|
|
-- 2. in the 'dicom.ini' of your web server, create the dwv viewer:
|
|
-- >> [dwv-simple]
|
|
-- >> source = dwv-simple.lua
|
|
-- And set it as the default viewer:
|
|
-- >> [webdefaults]
|
|
-- >> ...
|
|
-- >> viewer = dwv-simple
|
|
-- 3. copy the DWV distribution files in a 'dwv' folder
|
|
-- in the web folder of your web server. It should be accessible
|
|
-- via '[server address]/dwv'.
|
|
--
|
|
-- This script relies on the 'kFactorFile', 'ACRNemaMap' and 'Dictionary'
|
|
-- variables being set correctly.
|
|
|
|
-- Get ids
