CADDLAB Medical Imaging on Remote Compute Servers

Introduction to the Project The Department of Radiology has servers that store 3D medical images (124,000!) Web-based system known as PACS Project designed to view images over web, point and click processing, command line programs Authorization and security already handled eXtreme Programming!

Domain Problems In past, clinicians had to download whole 3D image before being able to process Excessive download times and wasted resources Because of the large file sizes, clinicians need an efficient way to view and process the images online

Key Use Cases After logging in, the user will see the main page. After logging in, the user will see the main page. Here he/she will choose an image and select one of two commands The View Command will allow the user to view and/or select points on the image for processing. The View Command will allow the user to view and/or select points on the image for processing. The other command is the Blur Command that allows the user to run a process on their selected image. This processing is done on the server. Future commands will be added, such as registering and segmentation

Interfaces A Web site to choose images and the command to run A viewer (that we will demo) A Blur command page A Login Page (for now)

Architecture Repository architecture built around a database of 3D medical images Allows for the addition of future commands through the main page

Key Technical Problems Slow connections for downloading 40+ MB files Figuring out the technology to use We searched on google.com, found an applet called JIV We searched on google.com, found an applet called JIV We are not allowed access to their servers because they were just hacked Clinicians’ older computers Team’s slow laptops

Technologies The viewer is a Java applet based on a program we found called JIV The website will use html and php (tentative) Image converting, connecting with the database Client will take care of security
