of the system until it has been thoroughly inspected by authorized INSIGHTEC service
personnel.

3.8. Storage and Maintenance of the DQA Phantom Gel
The DQA phantom gel is a solid water based cross-linked gel, embedded in a rounded plastic container, and
protected by a Mylar membrane.
1. Always check the expiration date on the DQA phantom gel before using it; If it is expired, order a new
phantom gel. Expired phantom gel should not be used.
2. Inspect the phantom for cracks and chips; if any appear, order a new phantom gel.
3. If the surface of the phantom is defective, a replacement phantom must be ordered from INSIGHTEC
immediately. The defect may trap air and cause beam deflection.
4. Verify that the Mylar membrane protecting the phantom gel is intact and tightened. In any case of holes
in the Mylar membrane, bacteria may quickly destroy the phantom.
5. Close the bottom cover of the phantom gel and store it in a cool, dark location.
