In an attempt to gain a foothold in the medical market, Pixar donated ten machines to leading hospitals and sent marketing people to doctors' conventions. However, this had little effect on sales, despite the machine's ability to perform CAT scans and show perfect images of the human body. Pixar did get a contract with the manufacturer of CAT Scanners, which sold 30 machines. The terms were: Buy a million dollar scanner, and get a $30,000 3D visualization system free. However doctors were not trained to look at 3D, and could be sued unless they looked at the individual slices, per their training. By 1988, Pixar had only sold 120 Pixar Image Computers.
