The cardiac modeling tool is tailored to assess function in cardiac segments by full kinetic modeling, and to compare the outcome against normal databases. The image fusion tool not only allows to register images, but also enables the user to explore the calculated functional images in detail. Further interactive investigation is facilitated by the versatile 3D rendering tool. A fully automatic analysis of FDG data from patients with suspected Alzheimer's dementia is provided by the Alzheimer's discrimination analysis tool which is based on the outcome of a vast multi-center trial. Based on the normal brain database tool users can implement unique strategies to establish their own brain analysis procedure for new tracers or specific diseases.
