Success criteria
The user can load 2 different images, and they would display concurrently one next to the other. During scrolling the same area of the body should be displayed (for well-registered sample images) based on the supplied metadata. While moving the mouse cursor on one image the position of the cursor in the same physical spot on the other image should be displayed (physical location calculated from spatial metadata).
