Welcome to DiagnosisX 


DiagnosisX is a simulated medical encounter with a virtual patient. It is designed to allow medical students and others the opportunity for unlimited practice at interviewing and examining patients, ordering tests and imaging. It allows them to establish and modify a differential diagnosis as they work through the case. At the end of the case, the student’s management of the encounter is compared to that of an expert and the rationale for each step is provided to the student.

DiagnosisX is also an authoring package that allows medical teachers to create and publish their own multimedia cases to the web. There is no requirement for technical help to complete the process and no waiting for the final product. It can all be done by a faculty member with average computer skills who like to teach by using cases.

The DiagnosisX Philosophy 

DiagnosisX has been designed to promote generous sharing of teaching resources. The DiagnosisX software is provided without charge. In return, authors publish their cases to a central repository of cases. This repository is in turn available to students and other teachers around the world.


It takes a substantial amount of time and effort to create a complete and pedagogically polished case. The idea is: “Let’s work together, create a really useful teaching resource and share in each other’s efforts and domain expertise”.  In this way our individual work as teachers can be disseminated far and wide, students gain access to the best teaching material and ultimately patients gain the benefits. This is what we think it should all be about.



IntroIMG03DiagnosisX is up and running. Nonetheless, the creators consider it to be a work in progress. We plan to add many new features and vigorously encourage new suggestions and constructive criticism. We see DiagnosisX evolving in a manner consistent with the wishes of and incorporating the ideas of the teachers and students. It is meant to be an open collaboration of community scholarship and practical usefulness.

For Authors:

In order to create and publish virtual cases, authors require the following:
1. Internet Explorer 7.0
From the Internet Explorer website:
 “Internet Explorer 7 will run on Windows XP Service Pack 2 (SP2), Windows XP Professional x64 Edition, and Windows Server 2003 Service Pack 1 (SP1). Memory requirements listed below are for Internet Explorer itself. Any machine with the recommended amount of memory for Windows (for example, 128 MB for Windows XP and 256 MB for Windows XP Professional x64) will meet the memory requirements for Internet Explorer 7”.

2. Microsoft’s .net framework 3.5
Microsoft’s .net framework 3.5 is an optional part of their standard operating systems. It can be downloaded from their website free of charge if it is not already installed on your computer.

3. DiagnosisX authoring package
The DiagnosisX authoring package is available from this website – just click on the “download” button at the top of this page. This program is frequently updated. You can check to see if you have the most recent version by clicking on the help button of your current version. The DiagnosisX authoring tool works with Windows XP and Vista. It does not work on Apple.

For Students:

Students require only a standard web browser. It works on Internet Explorer 6.0 and 7.0 and Mozilla Firefox running on PC’s and Apple. Internet explorer 5.0 may be sufficient but we have not tested this extensively
