In order to manipulate images, you had to use a mouse and position the cursor on one of the GUI controls. As you get more and more monitors, that becomes more and more cumbersome. ITL took the GUI controls off the monitors used for image viewing and placed them all on a single touch screen that sits as a control panel right in front of the radiologist. That's why they're used in many industries like fast food. You just touch the screen for the next operation you want to go through.
Screen space can be expensive.
Putting all of the GUI controls on a touch screen allows the use of every pixel on the high-priced monitors for image display. If you place a band across the top or down the side of that monitor for GUI controls, you lose a whole row or column of images. Ryon said the company has one beta site in operation and plans to begin marketing the system in the third quarter of this year.
