In brain imaging, the adoption of applications that provide novel analysis and image processing techniques is slow. The main reasons for this are: a specialist is required to make these applications function correctly, complex software packages and computer libraries are required by these applications, and large amounts of computational resources are needed to complete the analysis in reasonable time. Web portals are a popular approach to overcome these barriers to adoption. These portals can be accessed via a common web browser and allow users to run applications on remote computers. A major disadvantage of this approach is the effort required to develop and maintain such portal systems.

The UK National e-Science Centre has developed a method for quickly developing portals. This method, called Rapid, generates portals from one description. These descriptions are easy to produce and require no conventional computer programming. Once a description is produced, Rapid converts it into a live web portal. Such a web portal then allows an end-user to configure a task by selecting input data and setting parameters. It then takes care of submitting and monitoring the task to remote computers. Once the task is finished, the results are sent back to the portal and shown in the web browser.

We show a first version of a prototype of a perfusion image analysis portal, which we are developing for the SFC Brain Imaging Research Centre. Input data for the analysis consists of reconstructions of DICOM slices in the Analyze format, as produced by the application FLIRT. A bespoke analysis developed at the SFC Brain Imaging Research Centre is then used to perform perfusion imaging.

We have developed a prototype web portal for perfusion image analysis. The major advantages of this portal are: (1) it was developed quickly, (2) it is easy to maintain, (3) it provides an intuitive interface, and (4) it speeds up the process considerably.
