MULTI-PURPOSE BODY PHANTOM
End-to-end Radiotherapy System Testing
The QUASAR™ Multi-Purpose Body Phantom is designed to test the
complete radiotherapy system through a series of nondosimetric and
dosimetric evaluations. True to the original QUASAR™ Body Phantom
developed(1)(2) by Jake Van Dyk at the London Regional Cancer
Program, the Multi-Purpose Body Phantom uses a wide variety of test
objects in a solid acrylic oval to perform many of the no ndosimetric
quality assurance tests recommended by TG 53 and TG 66.
The Multi-Purpose Body Phantom can also be easily converted to
an IGRT gating phantom by adding the QUASAR™ Programmable
Respiratory Motion Assembly, thereby offering a cost-effective way
to increase overall testing capabilities.
Key Features
• Dosimetric and nondosimetric
tests for end-to-end radiotherapy
system testing
• Published pass/fail criteria for a
number of tests in the TG 53 and
TG 66 Reports
• Interchange inserts quickly and
easily
• Used for IMRT, IGRT, VMAT, SRS
and Tomotherapy
• Converts to an IGRT gating phantom with the addition of the
QUASAR™ Respiratory Motion Assembly

Dosimetric Measurement Capabilities
•
•
•
•
Verify dosimetry calculations with ion chamber measurements; compatible with ion chambers from major suppliers
Measure in low or high dose areas with multiple measurement locations throughout the phantom
Perform homogeneous density measurements with blank acrylic rods and inserts
Use inhomogeneous inserts to test density corrections in an idealized near anthropomorphic geometry

The Quality Assurance System for Advanced Radiotherapy (QUASAR™) supports the testing of a wide variety of dosimetric and nondosimetric functions of planning systems, CT
simulators and delivery systems.
QUASAR™ is a valuable part of any quality assurance program. From respiratory motion and MLC beam geometry to daily on-board imaging QA, QUASAR™ phantoms and
software are ready to be incorporated into your QA protocols for regularly scheduled testing. They are also effective for commissioning new systems and upgrades, and testing
repairs.
Designed by and for medical physicists, QUASAR™ quality assurance tools provide you with confidence that every patient is getting the best possible treatment.
