phantomlab SRT (Steriotactic Radiosurgery) End-To-End Phantoms Phantom

LIQUIPHIL™ END-TO-END PHANTOM
The LiquiPhil™ End-to-End Phantoms were developed to provide stereotactic localization and dose verification for radiosurgery machines. The phantoms may be used for a variety of radiation therapy applications including periodic quality assurance evaluations and acceptance testing and end-to-end testing in conformance to AAPM TG-54. The phantoms may also be used to perform re-evaluations after equipment or software upgrades.

Charles W. Coffey, II, Ph.D., established the design criteria that The Phantom Laboratory used in constructing the LiquiPhil™ Head Phantom and LiquiPhil™ Pelvis Phantom. In 2013 The Phantom Laboratory worked with Michael S. Gossman, M.S., DABR, FAAPM, to develop the LiquiPhil™ Head Phantom with Bite Feature, providing for both stereotactic radiosurgery and radiotherapy quality assurance with bite tray systems.

For detailed information please refer to the LiquiPhil™ Head End-to-End Phantom and Data Sheet, the LiquiPhil™ Head Phantom with Bite Feature and Data Sheet (Bite Feature) or the LiquiPhil™ Pelvis Phantom Manual and Data Sheet.

Available END-TO-END Models
LiquiPhil™ Head Phantom: A water filled head with a repositionable tumor vessel that can be adapted to accommodate ionization chambers, TLDs, film or dosimetric gels. Ideal for testing stereotactic treatment using halos, and surface monitoring positioning systems.

LiquiPhil™ Head Phantom with Bite Feature: This model is similar to the LiquiPhil™ Head Phantom with the addition of a bite feature for use with immobilization bite tray systems.

LiquiPhil™ Pelvis Phantom: A life size pelvic form with with a repositionable tumor vessel that can be adapted to accommodate ionization chambers, TLDs, film or dosimetric gels. Ideal for pre-treatment verification for both conventional and IMRT plans. 

Design
The phantoms’ design provides full simulation of the localization and irradiation sequences. The anatomically accurate forms are filled with water to simulate the radiation absorption and scatter of human soft tissue. The heavy-duty outer shell of the LiquiPhil™ Phantom is designed to accommodate the anchoring screws needed for proper positioning head frames. An internal container called a tumor vessel can be positioned anywhere within the head form by manipulating an external position rod. This vessel may be filled with either a radiation-sensitive gel for alignment evaluations or with radiation dosimeters for quantitative dose measurements. The LiquiPhil™ Head Phantom with Bite Feature features a movable lower jaw and upper teeth provide for the use of bite tray systems. 

For conventional and IMRT dose distribution and verification the LiquiPhil™ Pelvis Phantom is an excellent tool for final quality verification of therapy dose delivery and for comparing the delivered dose profiles for different treatment plans.
