## Introduction

This help file explains how to use the application. This application allows you to view DICOM images. Please make sure you have read the license text in the "About" dialog.

The application automatically starts when you enter a CD-ROM with the software embedded. Please note that your operating system may have disabled this feature. In this case you can run the "<your CD-drive>:\autorun.exe" directly from the CD-ROM.

## Mouse control

You can pan an image by moving the mouse while keeping the left mouse button pressed.
You can window / level an image by moving the mouse while keeping the right mouse button pressed. A vertical movement will change the window center, a horizontal movement will change the window width.
In CT/PET Viewing mode, you can change the fusion mix of the fusion viewport by moving the mouse while keeping the right mouse button pressed. A movement to the left will change the mix towards the CT image, to the right to the PET image.

## Buttons

Browse for new images from CD. When you browse for images you can search for files of types:

- DICOMDIR: This file references multiple DICOM images. If opened it populates the treeview in the left pane with patient and study information
- *.DCM: This extension represents DICOM image files. Each file contains only one image. Thus only one image can be viewed
- *.*: This extension represents all files. Each file contains only one image. Thus only one image can be viewed
