Phantom Desiccation

Over time, the phantom's water-based gel will slowly lose moisture. This process is ac-

celerated by high temperatures, incorrect storage, and damage to the case or scanning

surface. Consistently storing the phantom in an air-tight container will contribute greatly

to long phantom life. A properly stored phantom will reduce the amount of moisture lost

per year.

For most climate-controlled environments, the phantom weight should be checked

every six months. Phantoms used in high temperature/low humidity environments or in

mobile situations should be tested more frequently. As the phantom desiccates, the

scanning surface may flatten out. It is suggested that the phantom be sent in for rejuve-

nation once it has lost 15 grams of its total weight. When this occurs, contact GAMMEX

(1-800-GAMMEX-1).
