With the advent of high-bandwidth wireless networks and pervasive computing, the space and platform barriers for visualization are being broken. We use the term "pervasive visualization" to refer to visualization using mobile devices in a pervasive computing environment.

In this poster, we investigate how to achieve visualization in a pervasive visualization environment, especially on new platforms such as PDAs, cell phones, and other mobile devices that have very limited resources and usually are not considered appropriate platforms for visualization. We will use a clinic application as an example and our target application. In this system, patient data, such as CT and MRI, are stored in a central server in the hospital and physicians can access these data using a cell phone for a quick preview, a pocket PC or laptop for some initial diagnosis, and a powerful workstation for any further diagnosis
