Page 3: Overview
OVERVIEW The CIRS Dose Verification Head and Shoulder Phantom is designed for end- to-end testing of treatment planning systems from imaging acquisition through dosimetry verification. The high fidelity anthropomorphic design contains complex internal anatomy that provides a realistic clinical simulation to evaluate the chal- lenging effects of intra- and extra-cranial anatomies. -
Page 4: Description Of The Phantom
DESCRIPTION OF THE PHANTOM The phantom is based on the standard CIRS Model 038 Stereotactic End-to-End Verification phantom (STEEV) and consists of two major components: head and shoulders that are permanently attached. Head is cut axially at the vertex parallel to the Frankfort horizontal plane. - Page 5 POSITIONING AND FILM REGISTRATION The phantom contains unique features for proper and repeatable orientation, posi- tioning and film-to-treatment plan registration. Laser alignment marks (crosshairs) are aligned with an anterior hole and positioned on the vertex, front and sides of the head and shoulders.
- Page 6 The posterior portion of the phantom contains five (5) CT fiducial pins for film-to- treatment plan registration. Four fiducials are located in an orthogonal configuration and a fifth fiducial is 10 mm offset to avoid mistakes in film registration. They are made of stainless steel and measure Ø...
- Page 7 ION CHAMBER DOSIMETRY The phantom is configured for use with PTW 31010 Semiflex 0.125 cc ion chamber (CIRS cavity code CV511C), but can accommodate different ion chambers, diodes or other detectors upon request. To use an ion chamber through the IS holes in variable positions each...

- Page 9 Electron Density To perform the electron density calibration the shoulders accommodate five (5) permanent locations for electron density plugs: cortical bone, trabecular bone, lung inhale, lung exhale and water. Plugs measure Ø 2.5 cm x 3 cm long. Bone plugs are positioned at the approximately humerus locations.

Page 11: Use Of The Phantom
USE OF THE PHANTOM GENERAL INSTRUCTIONS 1. Carefully remove phantom from carry case. 2. Position the phantom face up on a clean, flat surface. 3. Unbuckle the nylon strap. Using the screw driver provided, un- screw the two nylon screws from the vertex, starting with the lower screw. - Page 12 Screw the temporary black nylon thumbscrews to the anterior portion of the phantom. Lift anterior portion of the phantom from the posterior end using black thumbscrews. Carefully place on a clean, flat surface.
- Page 13 Position film of the desired size on the flat surface of the posterior portion making sure it covers CT fiducials. CT fiducials are sharp so they can secure the film. Use care during assembly, disassembly and film placement to ensure you do not scratch yourself or the film, or bend the fiducials.

Page 14: Care & Handling
Epoxy is quite durable, but can still be damaged if it is dropped on a hard surface; so handle with care! Most phantoms can be easily repaired. If damaged, contact CIRS. It is recommend- ed that the phantom only be cleaned with mild detergent and water. Avoid solvent based or abrasive cleaning agents. - Page 15 APPENDIX (CONT.)
