What means "CASIM@GE"?
The word "CASIM@GE" is the fusion of words "Case" and "Images". The "@" letter symbolize internet. Project "CASIM@GE" is an institutional project (No: 97755) of Geneva University Hospital (HUG, http://www.hcuge.ch/). It is developed in the Digital Imaging Unit (UIN, http://www.expasy.ch/UIN/).
The goal of this project is to help the development of digital "teaching files" databases. A database is a collection of imagery cases. Each case contains several images of any modalities and a textual description. This "teaching files" database is an extension of our PACS (Picture Archiving and Communication System). This project provides a digital solution to manage and create these imagery teaching files: image browser, query system, editing software, ... This software is useful to any medical departments that produce images. A digital database offers many advantages over a "classic" teaching files collection: cost, duplication, transport, single-step process, web-access, ...
A lot of users (students, physicians, ...) are using this database. So, it was particularly important that the Graphic User Interface (GUI) is clear and fast. Browsing and searching have to be easy and image transfer from our PACS to the CASIM@GE database need to be a single-step process. This GUI is common to all platforms (MacOS, Windows, Internet/Intranet). Here is a preview of this GUI:
Database structure A general structure has been designed on the following idea: the CASIM@GE database is used by many users. There are many users. Each user is interested to manage one or more collections (personal, official, for teaching, for research, ...). All these collections contain one or more cases with one text description and many images. This database is a relational database. 4 tables are defined: users, collections, cases and images. Each table are linked together with a ONE-TO-MANY relation.
Project Description
Graphic User Interface
Database structure

We have 3 technical goals: - Collections are editable with any computer in our hospital, with MacOS or Windows. The system is based on a client/server network. - All collections can be copied on CD-Rom. These CD-Roms are stand-alone, with complete software to browse and view images, compatible with MacOS and Windows. - All collections can be viewed with any web browser in intranet/internet with all classic browsers (Netscape, Internet Explorer). To be able to meet these goals we selected 4th Dimension database software, by ACI SA (www.4d.com). Images and movies are handled by Quicktime technology, Apple Computer (www.apple.com/quicktime). We developed the database kernel in our Digital Imaging Unit (Unité d'Imagerie Numérique, http://www.expasy.ch/UIN/) with the help of a software company, Idem Informatique (www.ideminfo.ch). The HTTP interface, for web browsers, has been developed by another medical software company, CareOn SA (www.careon.com).
Technical choices

Network architecture
We use this new digital teaching files system since about 10 months. That is our statistic for these 10 months: 5100 Connections :
Our Experience
- 1734 via Client MacOS (34%)
- 1253 via Client Windows (24%)
- 1735 via Web (34%)
Duration:
- 1414 Hours
- 16 min / Connections
- 23 Connections / Days
Number of hours spent by all users per month on the CASIM@GE network

Our database already contains about 20'000 images for about 3500 cases. Many radiologists of our department are daily working with the database to add new cases to our collections. The integration with our PACS is a succes, PACS software and CASIM@GE work on same computer at same time without conflicts. Images are transfered easily wih a single-step process (copy & paste method). Because we use our PACS system to select and manipulate images, a radiologist of our department is able to learn the CASIM@GE network in less than 30 minutes. Many companies are interested to sponsor CD-Roms.
Here are some of our finished collections, that we have published on CD-Roms:
Many more are to come...
