Liquid fillable phantom for IMRT dose distribution measurements
The RSVP Phantom™ was developed to provide localization and dose verification for IMRT machines.
Charles W. Coffey, II, Ph.D. established the design criteria that The Phantom Laboratory used in constructing the RSVP Phantom™ Pelvis. The phantom may be used for a variety of therapy applications, including periodic quality assurance evaluations and acceptance testing. The RSVP Phantom™ may also be used to re-evaluate systems after equipment or software upgrades.
The RSVP Phantom™ Pelvis includes a liquid-fillable lifesize pelvis form. The form is filled with water to simulate the radiation absorption and scatter of human soft tissue. An internal container called a tumor vessel may be positioned anywhere within the form by manipulating an external position rod. This cylinder may be filled with either a radiation sensitive gel for alignment evaluations or with TLD dosimeters for quantitative dose measurements.
The Phantom Laboratory has developed an optional holder that allows positioning of TLD dosimeters in the tumor vessel. To measure dose, a TLD chip or dosimetry gel is placed inside the tumor vessel. As in the localization evaluation, standard protocols are used to locate the tumor and irradiate the target area. The dosimeter is then removed from the phantom and read. The phantom can also accommodate specially designed chambers. (For more information on commercially available detectors, contact The Phantom Laboratory by phone or e-mail sales@phantomlab.com.)
